Founder’s Guide to Building Decentralized Web Applications (Dapps)

Decentralized Web Applications popularly known as Dapps have been gaining attention lately. In 2019, the Daaps market was valued at only USD 10.52 Billion, however, experts predict that by the year 2027, it’ll exceed USD 368.25 Billion. 

But why is building Dapps a big deal, are they any better than our traditional apps?

While it’s debatable, the short answer is, yes. To help you better understand “why?”, let’s start with the definition of Daaps.

What is Dapp – decentralized application?

Decentralized apps are programs built on blockchain technology or peer-to-peer (P2P) networks. Unlike regular applications controlled from a centralized location by a particular organization or government, Dapps back-end is decentralized and independent from individual control. These applications leverage smart contracts to build avenues where various industries, including the gaming and financial sectors, can perform tasks without centralized authorities.

In simpler terms, Decentralized Applications (Dapps) do not rely on the traditional client-server network model, which requires a central controlling authority to enable changes in the network and its maintenance. Instead, Dapps use a network of computers called nodes to function. These nodes are all equal participants in maintaining the network, and all actions are carried out independently at each node. As a result, all participating nodes have a complete record of the transactions. 

As much as other alternative blockchain networks exist, a more significant percentage of decentralized apps are built on Ethereum. The reason being, Ethereum has an excellent interface where developers can quickly and easily build decentralized apps. Also, the blockchain network allows for the quick launch of these applications.

If you want to tap into this lucrative business and wondering how to create Dapps, you are not alone. While hiring an in-house team of developers to build a decentralized blockchain app from scratch might seem ideal, it can be both a daunting task and expensive. Most companies outsource to reputable software development companies in Eastern Europe. Appvales is one of the leading in the region, and is well known for designing, building, testing, and deploying complex web and mobile applications. 

The company offers two options, you can let them handle the whole end-to-end product development of your Daap or they can serve as an extension to your product team through their dedicated engineers. Over the past few years, Appvales has successfully helped many companies bring their out-of-the-box business dreams to life, don’t hesitate to contact them

Daaps vs. Traditional web apps

The standard web app, for instance, Twitter or Uber functions on a privately owned computer system. That means the organization that owns and operates the computer system’s backend has unlimited authority over the app and its function. And with such great power, app-owning organizations can control how the users operate, for example, what they can post, visibility, etc.

DApps on the other hand operate on a blockchain network or a P2P network. Good examples of applications that run on a P2P network are Tor, Popcorn Time, and BitTorrent. These apps operate on computers that are part of the P2P network, and multiple people can consume, feed, or seed content, among many other functions without limitation.

In the context of blockchain, cryptocurrencies are the perfect example. They run on a blockchain network in a decentralized environment,  public and open-source. That gives them independence from control and interference by any single organization or government. For instance, if there was a Twitter-like dApp on blockchain, it would allow any user to publish messages. However, once posted, no one will be able to delete or alter the message. This includes the app developers and government.

Furthermore, Dapps brought a way to eliminate a single point of failure common with centralized ecosystems, and this is one of the reasons why its use case has exploded.

Key features of Dapps

Ever since the popularity of Dapps shot up and their benefits became well-known, many businesses are taking a keen interest in how to build decentralized applications.

However, before we get into the intricacies of how to create Dapps, understanding their key features is vital. This will give you a clearer understanding of how decentralized applications work, which goes a long way to ensure you make an efficient and functional program.

Most of the features of the decentralized technology will rub off on Dapps. So, without further ado, here are some of the critical elements that make Dapps interesting;

  • Decentralized: One of the most prominent features of Dapps, as their name suggests, is they are decentralized. The applications are built on the blockchain. Hence, the programs are run by network actors, and no single organization can control or shut down its functions.
  • Lack of intermediaries: Unlike centralized applications, Dapps cut out the need for intermediaries. Instead, smart contracts automate and manage the system. As such, it eliminates the need for a central figure to authorize activities on the network. 

If, for example, you were to build an app like Twitter on blockchain technology, app users would be able to post and tweet. However, even you, as the app owner, would not be able to delete the tweets. You do not have the authority to do so.

  • Open-source: Dapps are created using open-source codes which means that the codebase is open to the general public for continuous improvement and review. Thus, Dapps are easily customizable and can integrate with various systems, software, and tools, resulting in efficient use and administration of the application.
  • No downtime: One of the well-known characteristics of Dapps is there is never a central point of failure, as is the case with centralized applications running on a single hosting server. Dapps are connected to several nodes across the globe, which eliminates the risk of the entire network collapsing.  
  • Censorship resistance: Dapps can not be held at ransom by a centralized figure of authority since they are not controlled from one server.

Let’s again use the Twitter example. If, for some reason, Twitter needed to shut down tweets today, all the owners need to do is cut off communication to the central server. However, if the application were built as a Dapp instead, this would not be possible. Since Dapps operates on a peer-to-peer network, one node could be communicating with other nodes in the network, which will keep the tweets flowing. As such, it is tough for one figure to censor the network or gain control of it.  

  • Incentive: Most Dapps employ one of the use cases of blockchain–cryptocurrency in their solution. For instance, a gaming Dapp can have a token attached to it to incentivize its users every time they play a game. The same goes for Betting Dapps, as users may have to place their bets with the token. Also, users and miners on the network can be rewarded with the token. 
  • Protocol / Algorithm: Dapps are built using specific algorithms that can aid in generating tokens that will serve as rewards for network participants
  • Blockchain Data: The blockchain is an essential feature of DApps as they are stored cryptographically on the distributed ledger. 

Dapps Types 

Dapps are classified according to the blockchain model and algorithm it is built on. If you are looking forward to building Dapps, these are the three types of Dapps you need to know. 

  • Type 1 Dapps: These Dapps are built on their blockchains, such as Ethereum and bitcoin. You can also find them on other alternative coins that have their blockchain.
  • Type 2 Dapps: in this category, we find decentralized applications that leverage on the Type 1 blockchain. To function, they have to issue out tokens necessary for their functionality and rewarding participants in the blockchain. Most Ethereum based smart contracts apps are built on the Type 2 Dapp.

One example of this type of decentralized application is the Omni Protocol built on the Bitcoin blockchain. Facilitated by smart contracts, Omni acts as a layer that allows users to trade and bet with tokens while eliminating the need for intermediaries.

  • Type 3 Dapps:  These types of decentralized programs leverage Type 2 Dapp protocol to underwrite any token they issue. A Type 3 Dapp is a great option, especially if you want to build a decentralized website. A good example is the SAFE Network (Secure Access for Everyone) which leverages the Omni protocol to issue Safecoins. The SAFE network is an autonomous decentralized data network that enables the creation of websites and applications that can withstand censorship. 

How Does The Process of Building Decentralized Application (Dapp) Look Like?

Dapps are the new frontier in the programming world and are an excellent way to increase revenue. As expected, many companies are eager to build on this ground-breaking technology.

In this section, we will look at things that should remain top of mind when you build a decentralized blockchain app. 

Let’s dive into details.

UI/UX design: 

The user interface and user experience (UI/UX) are the first things you should consider in your decentralized application design & development.

These two elements usually go together since the UI contains all aesthetic elements that would enable ease of interaction with the Dapp, significantly impacting the user experience. These aesthetic elements include icons, buttons, menu bars, colors, typography, etc. 

The importance of UI cannot be over-emphasized. An excellently designed UI is attractive, which improves user experience. In turn, you will witness increased traffic to your decentralized website or application.

Tech stack selection:

It is essential to ensure that you select the tech stack needed for the Dapp software development.  A technology stack contains the software, tools, frameworks, and programming languages required for the client-side and server-side to create and develop the decentralized site or application.

You may pick a tech stack based on your preferences. However, it would be best if you first considered the scope of the project. Which blockchain protocol, framework, hosting, or API would be your Dapp’s best suit? Which tools will facilitate a more accessible and quicker Dapp development process?

Development stage (backend + frontend): 

The efficiency and functionality of decentralized applications majorly depend on the front-end and back-end development. 

Front-end development involves writing codes that design the app’s visual elements, while back-end development is the programming of all background processes. Just like regular apps, developers write the DApp code in their preferred language. 

The use of smart contracts, for instance, is essential in the development of Dapp on Ethereum, which is something you need to consider. Also, the frontend code can be hosted on decentralized storage such as IPFS or Swarm.

Additionally, If you want to learn how to develop Dapps, you must grasp Solidity, the standard programming language developers use to build Dapps on its most popular platform – Ethereum. Other alternatives to Solidity include Vyper, an experimental language that increases simplicity and security. Vyper is much simpler and makes the code less buggy as it is human-readable. Simplicity is another interesting language that uses static analysis tools to cut down costs. It also uses Coq to avoid hacks and denial of service.  

Deployment and Testing:

After you have coded your Dapp, it’s time for deployment. However, don’t be in a rush.

Decentralized applications are hard to alter. Also, they will be stored in the blockchain for good. As such, you need to be sure that the application functions exactly how you want it.

To confirm that the Dapp is efficient, launch it on a testnet. Ensure the codes are examined, test them for functionality, and fix any bugs before the codes go live. It is only after thoroughly testing the Dapp and affirming its efficiency that you can launch it.

These are the primary development stages you should familiarize yourself with if you want to know how to create a decentralized website or application that is both efficient and functional.

You can also choose to build the Dapp from scratch or on an existing network or protocol. However, there are unique challenges that come with learning how to develop Dapps. For instance, the development process is intensive, one of the key reasons why you may need to outsource. The importance of a development team that has an in-depth understanding of the features required, smart contracts, and the ideal decentralized application platform cannot be over-emphasized.

Minimal Team Roles Needed: 

When it comes to building a decentralized app it takes a team of dedicated and experienced software developers to take your idea from the ideation stage to deployment. 

Here are the team members you should round up to work on the Dapp to ensure its success.

  • Project Manager

The success of your decentralized web application lies in the competence of the project manager. 

The project manager is in charge of planning, budgeting, and ensuring the completion of the project by overseeing the people working on it. 

  • Front-end developer

The design of your Dapp, structure, and functionality lie in your front-end developers’ expertise. The aesthetic and functional design is balanced and optimized to ensure users can access and navigate the application via mobile or desktop fast and with ease.

  • Back-end developer 

The back-end developer builds and maintains the components that make up the application’s background processes. They write codes that execute user commands and actions.

  • Blockchain developer

Since the Dapps is built on blockchain technology, there is a need for blockchain developers. These developers are responsible for deploying smart contracts, data structures, and cryptography.  

  • Business analyst

There is a bridge between your tech idea and its delivery to your target audience, and a business analyst can ensure the application’s success in the market. They will conduct business analysis on the application, your target audience, and its overall profitability.

  • DevOps engineer

A DevOps engineer ensures balance in the Dapp development life cycle, from inception to programming, deployment, and maintenance. 

  • Quality assurance engineer

A quality assurance engineer ensures that every aspect of the decentralized web applications works as it should from the commencement of the project to its launch. They test the application at each stage to ensure it is up to standards and in compliance with the relevant regulations.

How Much Would It Cost to Build a Decentralized Application (Dapp)?

There are multiple factors to consider when building a decentralized app, and one of them is the cost. 

How much will it cost to take the Dapp from the Ideation stage to deployment?

This is a question many entrepreneurs want to be answered.

Dapp development will cost anything from $10,000 to $100,000. 

These figures are far-stretched because the cost of building a Dapp depends on various moving parts. For instance, the project’s complexity- its functionality, mutability, and interconnectivity with other ecosystems – is a major factor determining the amount of money you will invest in a decentralized application.

Also, you have to consider the price of third-party tools that a developer will integrate into the application. An excellent example of these third-party tools includes analytics, bug tracking tools, etc. Besides, continuous integrations and maintenance of your decentralized mobile apps is another expense to expect.

How We Built Yield Farming Pool Web Application Using React.js and Avalanche 

It took eight weeks to build the PenguinFinance Dapp using React.js – a programming language, and Avalanche, one of the fastest smart contracts available. In the end, we birthed Penguinfinance, a decentralized web application and crypto platform that provides yield farming on the Avalanche network. One of the features that make Avalanche ideal to create a decentralized website is that its validators secure its activities on the network using the proof-of-stake protocol. It is also very fast, low cost, and high performing. 

Key features 

Some of the key features of the Penguin Finance Dapp includes

  • Unlock Wallet. Users can compare their achievements actively, creating a competitive environment that makes an entirely transparent market for this cryptocurrency. 
  • Launchpad. This feature gives users of the platform fair access to funding. It is also a convenient way to deposit and withdraw currency, working with crypto exchanges and cold wallets.
  • Events. Users can participate in community events and get incentivized. Community events also include competing for the position of Emperor.
  • Compounder. Users can buy deposits from other users. 

Security and functionality are other factors that a software developer will look out for while creating a Dapp solution. With the PenguinFinance project, we successfully deployed the project with our team of dedicated experts.

How to Make a Live Streaming Platform [Case Study]

Live streaming has been with us for close to three decades. However, it is not until the last couple of years that the sector has seen tremendous growth.

With widespread internet usage and mainly due to the pandemic, millions of brands are leveraging this next-gen technology to promote consumer engagement and boost outreach. As a result, the industry has witnessed widespread popularity growing by 99% between April 2019 and April 2020.

Furthermore, the live streaming industry is expected to reach $70 billion by 2021. As such, it is only natural for brands to want a piece of the lucrative business; and one of the ways to do that is through developing a live-streaming platform

However, building an application that will help you ‘go live,’ as it’s popularly known, isn’t a walk in the park.

Live streaming app development needs rigorous planning. Brands need to make critical decisions that include determining the ideal platform and the best software development company for the task. Appvales is one such software development company with a pool of talented live-streaming app programmers. The company boasts an excellent track record building MVPs for startups as well as enterprise software.

In this article, we will guide you through creating a live streaming web application using as a case study.

How We Built – A Live Streaming Platform for Artists is a popular live streaming platform for unique artists with millions of monthly traffic. The platform was outsourced and developed by Appvales founders.

Core features

Let us look at the core features that will help you better understand how to make a live streaming platform.


Users can find live streams per category for easier search, from creative to fury, drawing, Illustration, Comic, Cartoon, Gaming, and more. They can also sort them as they wish.


Streaming screen

Users get the option to watch streams online while they chat with other players and artists. 


Watch multiple streams

Users can watch multiple (up to 4) streams simultaneously.


Subscribe and follow artists

Users get the option to subscribe and follow their favorite artists and get notifications on their streams and updates first.

Tech stack we used

We considered the platform and compared the third-party integrations to power the streaming app together and used the following technologies:

  • Programming languages: JavaScript, PHP
  • Frameworks: Node.js, React
  • Databases: MySQL
  • Cloud platforms: Amazon EC2, Amazon S3.
  • CDN services: Amazon CloudFront
  • Streaming protocols: RTMP, Adobe HTTP Dynamic Streaming
  • Media formats: MKV, MP4

Twitch Business Model is an online video streaming platform that allows users to watch or broadcast live or pre-recorded content. Twitch began as Justin. tv, a modest site for live video broadcasting, in 2011. Justin Kahn, the platform’s founder, received $8 million in venture capital for platform development that same year. was renamed Twitch Interactive in February 2014, and Amazon purchased the service for $970 million in August of the same year. Twitch now has about 15 million daily active users, over 9.3 billion hours of video watched, and over 27,000 partner channels.

Before you answer the question: “how do I create my own live streaming website?” let us consider Twitch’s business model and how they make money.


Over time, many businesses developed interests in video websites, thus attracting an even bigger gaming audience. Now they use Twitch as a promotional tool for their services and products.

Advertising on Twitch operates similarly to YouTube: first, the video begins with a brief commercial; then, ads show multiple times during the streaming and viewing.

Twitch charges gaming firms, websites, and developers a cost per mile (CPM) fee to run adverts. The CPM costs anywhere from $2 to $10.


Twitch users subscribe to channels at monthly rates of $4.99, $9.99, and $24.99. In addition, they may see videos without advertisements and enjoy premium Twitch features with paid subscriptions. 

Other available Twitch subscription features include Expanded Emoticon Set, Custom Chat Username Colors, Priority Customer Support, and more.

These features are acceptable to users because, by August 2021, the average number of concurrent Twitch streamers was 2.9 million.

Although Twitch Prime goes for $12.99 per month, Twitch’s parent business – Amazon – linked it with their retail website in September 2016, allowing Amazon Prime members to get Twitch Prime free.

Twitch Turbo is the streaming website’s second subscription option. By reducing commercials, boosting video storage, and providing exclusive chat emoticons and colors, the $8.99/month membership improves the game viewing experience.

In-App Purchases, Called “Bits”

Viewers can send live shout-outs to their favorite streamers with an in-app currency called “Bits,” in addition to cheering them on from Twitch Chat. Viewers can purchase Bits for as little as $1.40 for 100, which is equivalent to 1.4 cents per Bit.

These “Cheering Bits” are animated chat emotes, and for 1.4 cents, you can type “Cheer1” into Twitch Chat, giving an animated grey triangle. “Cheer100” makes a $1.40 dancing purple diamond. Users can cheer for any amount up to “Cheer10000” ($140), and emotes that correlate get bigger and more attractive.

Twitch receives around 70% of each Bit, with one cent going to the streamer.


Twitch users often pay for premium memberships to some channels to support their favorite streamers. In this case, Twitch and the channel owner share the membership fee equally.

Sales of clothing

This concept demands a platform to collaborate with cloth manufacturers and sell products to platform users. Twitch, for example, has a T-shirt firm as a partner. As a result, the most popular gamers make their T-shirt designs, promote them during live streams, and get a cut from the money.

MVP Features of Live Streaming Platform

After months of meticulous research, individual peculiarities have been put together to make a live streaming network like Twitch successful. When it comes to the UI/UX component of how to make a live streaming website like Twitch, you’ll need these essential features.

User registration 

This is where potential users register on the platform. When building a live streaming platform like Twitch, you should include other social login options so that visitors may register and log in to your website using their social media profiles, like Facebook. 

In addition, by connecting your streaming website to other social media platforms, you allow users to share live stream links with their contacts on social media, which attracts even more people.

User profile

Here, users can add personal information, preferences, and social media links. It also contains their interests, watching history, subscribed channels, membership details, and more.

Live chat

Live Chat is one of the fascinating features of a live-streaming network like Twitch. When considering how to create a streaming website, you want viewers from all around the world interacting with themselves and the broadcasters. This would give the impression of a real-life experience online.


If you intend to stream mostly paid content live on your live streaming platform, you will need to pay special attention to the platform’s security.

Also, your platform will require a secure payment gateway. IP-based access control, DRM, and AES encryption are the most common security mechanisms that work effectively with live streaming services.

Live video streaming

For 67% of viewers who utilize live video streaming services, the quality of the streaming video is the most crucial element. Therefore, you’ll need to use RTMP (real-time media protocol) for low latency connections to give users high-quality video streaming. To do this, RTMP divides the entire stream into smaller chunks for transmission between the server and the client.

Additional features

Other things to consider during the second development phase of your live streaming app are listed below:

Content that is tailored to the individual

Allow visitors to choose the most relevant content in the Discover section if the streaming website has various video categories. This way, they can watch new videos from their selected categories.


You must track user interaction, peak traffic, and viewership to make your platform effective. It would be a lot better if your analytics could compare traffic for various video events. This will help you know which streaming categories work well so you can provide a better customer experience.

Auto-categorization of videos

It’s nearly impossible to catalog streaming data in real-time manually. Artificial Intelligence (AI) and Machine Learning come in handy in this situation. You can employ AI and Machine Learning to automatically assess video material and prevent copyright infringement on your site.

Live streaming can be scheduled

Since people from various nations and time zones may visit your streaming website, you should include a feature that allows you to plan live streaming. For example, allow streamers to schedule the next session and notify their followers via Push Notifications about the new stream.


You can charge users for subscriptions, premium content access, or donations using a built-in payment mechanism.

Your payment processor should receive Credit and debit cards, PayPal, and other payment methods, such as Apple Pay. Twitch, however, uses the Xsolla payment mechanism.

How to Build Cryptocurrency Exchange Like Binance

Over the past decade, blockchain technology has captured global attention. The disruptive technology allows people to transact millions of dollars worth of cryptocurrencies online within minutes and in a few clicks. Blockchain revolutionized the financial systems — who could imagine that people can borrow US dollars and use cryptocurrency as collateral. 

Now, considering that trading in the crypto market can be volatile and risky, to get a chunk of this lucrative market easily, most companies create a crypto exchange platform instead. The exchange platform allows users to buy, sell, send, receive, or convert tokens from one form to another. Users can also convert their fiats to cryptocurrency. and throughout all these processes the exchange platform generates significant profits.

Whether you want to learn how to build a cryptocurrency exchange like Binance or create crypto exchange platform on a smaller scale, you are at the right place. Appvales is a software development company that has vast experience designing, building, testing, and deploying web and mobile applications for various industries, the cryptocurrency landscape included. You can let us handle end-to-end product development or introduce your product team to our dedicated engineers.

Regardless of the model you choose, you can rest assured our industry experts will help you build cryptocurrency exchange website that not only meets but exceed your expectations. This article further expands on how to create a cryptocurrency exchange website without breaking the bank or too much effort.

How does Binance work? 

Binance is an online exchange that allows its users to trade cryptocurrencies. The crypto giant also provides custodial wallets that will enable its traders to store their digital funds. Users also get lesser transaction fees by transaction with the exchange’s own token Binance Coin (BNB), which was initially built on ERC20 protocol but is now integrated into its own Blockchain- Binance Chain.

Binance is among the top-ranked websites in the global cryptocurrency exchange. The platform was founded in Hong Kong by Changpeng Zhao in 2017 and would later have to move its headquarters from China to Malta because of regulatory issues. Nevertheless, the Malta-based exchange is one of the best examples we can use in showing you how to make your own cryptocurrency exchange. 

Binance has over 1,338 markets and a multi-tier architecture that enables high security and can process about 1.4 million orders in a second. In addition, the platform has multiple features that give its users a wholesome trading experience. 

Let’s take a brief look at some of the features of the Binance exchange that you can replicate as you build your own crypto exchange.

Basic Exchange Features

Users need to register with Binance exchange to create an account. Binance adheres to KYC requirements for regulatory purposes. Upon completion of registration, users can add funds to their Binance custodial wallets or buy cryptocurrency from the peer-to-peer exchange features. Users can also utilize their credit and debit cards to buy cryptocurrency or use third-party services to buy and sell. 

Some other trading features that users can explore include: 

  1. Spot Trading: This feature supports limit orders where traders buy at a specific or better price, market orders that allow buyers to buy at market price, and stop limits orders that enable users to buy and sell at specified price levels. 
  2. Crypto Derivatives: Users can access over five order types, especially for future trades. They include limit, market, stop limit, stop market, trailing stop, post only, and limit TP/SL orders.
  3. Binance Earn: This feature explores, staking, and yields earnings for users. Users can deposit stable coins or any stipulated coin, lock it in for a specified tenure and earn interest rates for these coins.
  4. Binance smart pool: The Binance interface caters to all, including miners, who can earn by mining multiple cryptocurrencies and increasing their yield.
  5. Binance Visa Card: Users can convert their cryptocurrency to fiat and spend it with ease.
  6. Finance Launchpad: New crypto project looking to raise funds and get their tokens out to the general public. The launchpad is an incubator for businesses looking to raise funds.
  7. Binance Smart Chain (BSC): Binance launched its own Network with the BSC that allows smart contracts to be built on its blockchain, allowing developers to build decentralized applications (DApps) and solutions and solve some of the cross-chain issues plaguing the DeFi world. 
  8. The Binance API: You can learn how to develop cryptocurrency exchange simply by using Python and other programming languages to connect Binance API. The API allows you to automate your trading. It is a single-purpose API employing the HTTP Basic API key authentication model in addition to RESTful architecture. Users can utilise the API to access the platform via third-party apps.
  9. Binance Dex Clone Script: This feature allows people to build a clone-like exchange while retaining certain features of the original exchange. With the clone script, users can trade with one another and also have control over their funds. However, trading is limited to certain coins, including Bitcoin, Ethereum, BNB, Chainlink, Cardano, Polkadot, Tron, EOS, Litecoin, Bitcoin Cash, Ripple, Ethereum Classic, and Filecoin. 
  10. Security: To protect its users from hacks and phishing attacks, Binance employs address whitelisting. This helps users keep their funds safe simply by turning this feature on. Withdrawals will only be allowed to specific wallets, locking hackers out. In addition, Binance utilizes SAFU an ‘insurance’ that protects users in the event that the exchange gets attacked.  

Cryptocurrency Exchange Architecture 

Bitbox Cryptocurrency Exchange Architecture (source)

One of the biggest challenges facing cryptocurrency exchanges is designing infrastructure with risk-proof layers. In learning how to create a trading platform for cryptocurrency, carrying out in-depth research is imperative. 

First, you need to understand the desire of the client. Also, you need to know if the project will be built replicating patterns from specific industries. The exchange architecture, which is the platform’s structure, helps visually and systematically define how each component on the exchange relates and interacts; all elements on the platform from the login page, the user interface, the trading engine, API, security functions, and databases. 

Also essential to the Architecture is the technology stack – a set of development tools for creating the frontend and backend of the exchange. The technology stack contains programming languages, frameworks, libraries, APIs, compilers, and database management systems. 

Equally, some exchange architecture also integrates wallet security which involves having a cold wallet or multi-Signature into the wallet. An architecture that infuses both cold and hot wallets aids in protecting the users’ funds. The exchange admin can lock funds and prevent hackers from accessing them.

Binance employs an architecture such as this. For example, an emergency insurance fund called the SAFU, the Secure Asset Fund for Users. Equally, having the multi-sig feature infused into the architecture of an exchange adds more security. For instance, instead of having just a single key to log into your wallet, Multi-sig adds a layer of protection requiring signatures from multiple keys.

Additionally, an exchange requires AML (Anti Money Laundry) policies. This policy depends on the regulation of the country where the exchange is established. This layer of security can restrict certain transactions on the wallet, such as multiple withdrawals in a specific time frame or restricting the amount that can be withdrawn per transaction. In other words, the security architecture of the exchange is built to ensure that there are different layers of protection from siphoning off funds, internal and external cyber-attacks.

Key Crypto Exchange Platform Features 

There are different aspects a cryptocurrency platform may focus on. However, with the increase in the number of exchange platforms, we have witnessed a decline in the quality of many exchanges. As such, it is essential that you build an exchange that offers better solutions. 

So, as we look at how to create a crypto exchange site, we will see that creating a high-quality trading platform will require utilizing certain features, including:

Sign in/Sign up

One of the first things we look at as we build cryptocurrency exchange website is the login page. This is because, aside from standing as a point to allow people to register, it also protects the system. The sign-up page prevents unauthorized logins, manipulation, and hacking attacks. Hence, this feature must be created with utmost care and developed to its highest functionality. The page should consist of a login and password tab and added security functionality of 2FA for the users.

User Verification

Know-Your-Customer (KYC) policies are essential to crypto exchanges as regulatory measures demand them. Before a user can log in, the platform must verify they are the account’s rightful owners. As such, the verification feature improves the platform’s transparency and credibility.


The deposit and withdrawal feature allows traders to send and receive coins with ease. However, different exchanges have limits and fees attached to this activity, which depend on the company’s goal. 

Transactions creation

This feature varies as set by individual platforms. For most platforms, users can set trade orders amongst themselves while not transacting directly with each other. For some other platforms, users have to create a transaction order with the company itself. But whichever method an exchange uses, what matters is that users can place transaction orders without system errors. A simple glitch in the system can cost a user thousands of dollars, affecting the reputation of the exchange. Therefore, it is important that while you would want to start your own cryptocurrency exchange, you allow a user to undertake several transactions simultaneously without affecting the entire system. 

Internal API

Users need to exchange data amongst themselves, and this feature helps them achieve this. Also, the internal API allows the users to create automated trades using the exchange script designed for the platform.


The importance of a graph and status system for an exchange cannot be over-emphasized. It aids the users in getting better visibility before trading. 

Admin Panel

This feature enables the company to monitor the activities of its users, such as trades, verification processes, and the likes.

Things to Pay Attention to When Creating Crypto Exchange Platform

There are many factors you need to consider when creating a cryptocurrency exchange. Asides from making a brilliant technology, think about funding, staffing, getting directors and advisors on board, marketing, etc. Without proper guidance, it can be such a tedious and challenging process. 

Here are some of the factors to consider before thinking about how to build your own crypto exchange.


What is the ideal location for your crypto exchange? Imagine setting up a crypto exchange in India back in 2018 and having your exchange run into issues due to the unfavorable regulatory situations in the country. You need to find a location that offers a favorable climate for your business. Furthermore, Binance had to change its headquarters because of hostilities toward cryptocurrency from China to Malta. 


If you want to create an exchange that can rival Binance, you need financial injections. How do you plan to carry out the fundraising? Venture capitalists, crowdfunding, ICOs, and IEOs are great funding options.

Exchange Type

For most individuals, building an exchange from scratch can be challenging. Utilizing Clone Scripts is a less tedious process. Clone scripts are clones of exchanges such as Binance. They are built like a decentralized peer-to-peer exchange that you can buy easily. Other methods include integrating the exchange API, peer-to-peer exchange, or full exchange with trading features.   

In addition, consider providing single or multiple fiat currencies if you build own crypto exchange. There are many regulatory red tapes to consider if you decide to go this route, and this may be one reason why a clone script may be an ideal choice. 


When you determine the kind of exchange you want to build, find out the level of security infrastructure you need. You may want to consider getting a reputable software development team to design the security architecture. 

Regulatory compliance

Although more governments across the globe have begun to accept cryptocurrencies, there are still stringent and uncertain regulations surrounding virtual money. It is therefore vital to choose a competent legal team conversant with the global regulatory framework. Furthermore, cryptocurrency exchanges do not function the same way in different countries, which is why you need legal advisors.

Liquidity Management

Coingecko ensures that users can see the liquidity and fluidity of their preferred exchange platforms. It is important to ensure that you have strategies and processes that will help you manage your liquidity flow better. 


Having the right marketing strategy and budget can mean a whole lot for a cryptocurrency project. You want your exchange marketed on the right platform, not on Facebook and Google platforms that still regulate crypto-related content. So, have a proper marketing strategy to advertise your products to your target audience. 

When thinking about how to build your own bitcoin exchange, consider a referral feature as part of your marketing strategy. With this feature, existing users can refer new users to the platform for a bonus.

How to Build Your Own Cryptocurrency Exchange

There are various aspects that you need to incorporate into your cryptocurrency exchange platform to ensure success. They include:


The UI/UX design of any platform is the first thing a user sees before using the application. The design must be simple, aesthetically pleasing, and user-friendly. To create a harmonic design that combines elegant design and usability, including a Wireframe. This serves as the base of the design where its key features are integrated into the prototype.

Front-end development

This part of the application focuses on the website’s client-side and can be designed with HTML, Javascript programming languages (React.js, Angular.js, Vue.js frameworks), and CSS markups.  

Backend development + API

While the backend development is vital for a project, the user does not directly relate. It is responsible for handling server-side functions of the admin panel, user authorization, and authentication. The back end handles essential functions and is the internal logic of the app. 


Different testings will be carried out on the application to ensure that most bugs are eliminated within the frontend and backend before it is launched. More tests are still carried out to ensure it is secured from cyber and system attacks before launching the application. 


The first step of protecting users is complying with regulatory demands such as know your customer policies (KYC). Also, sensitive information such as user data and funds need to be protected to prevent hacks and data leaks. Strategies such as building a secure architecture with encrypted keys stored in dedicated secured servers, utilizing user authentication, and specifying their IP address can protect the system. In addition, the SHA-256 algorithm can be implemented in exchanging encrypted data, thereby providing a secured infrastructure. 

How Much Does it Cost to Build ​​Cryptocurrency Exchange Like Binance? 

It has taken Binance a little over four years and millions of dollars to build the full-featured binance analog application. The basic version of the exchange can be built within 4-6 years and cost around $70 000 – $120 000, while the full-feature analog system can take years to execute and costs hundreds of thousands of dollars. If you are seeking to build cryptocurrency exchange website just like Binance, the cost can be broken down as: 

  • Front-end development: Cost: Approx. $50000
  • Back-end development: Cost: Approx. $40,000-$50,000
  • Blockchain Integration:  Cost: Approx. $5000-$10,000

Migrating from Angular to React – CTO Playbook

The constant changes in JavaScript and other frameworks such as React have brought massive improvements to writing code. However, it has also been a thorn in the flesh for software developers trying to match up with the rapid advancements in the field while maintaining older, legacy programs such as Angular 1. 

Considering Angular 1 web applications are piling by the day, it’s increasingly becoming more difficult to scale the UI and add progressively more complex features. While this differs with each use case, and the amount of information that needs to be processed, the most common result is performance degradation, rendering slowdowns, troubles with interactivity, and sometimes race conditions.

To keep up, most companies are moving to React. However, migrating from Angular to React is no walk in the park, thus it needs to be done right and by expert professionals.  This is essential to avoid unprecedented problems and costs in the future. Fortunately, for you, our developers at Appvales have successfully worked on countless projects that required migrating from Angular to React. You can rest assured that we will handle your end-to-end product development flawlessly.  

Appvales can also collaborate with your product team through our dedicated mobile development model. We are a software development company with more than a decade of experience in software development. 

When you think of migrating, deep knowledge for both frameworks is a must. In this article, we’ll explore:

• the opportunities and risks of migrating from Angular to React

• the best practices for easy migration

• how to migrate large scale apps

We’ll describe these techniques in great depth to help you be successful with code migration. Let’s get started!

Why migrating to React is a Good Choice?

Do you probably ask why migrate to React? Is the process worth it? Is it because it’s the developers’ most loved framework? 

Well, there are so many reasons why you should choose to migrate from Angular to React. Here are some of the best ones:

React’s API is simple

React has nine lifecycle methods that you can use to control your components. However, you might only need to use a few, even in the case of a mature React application.

In addition to that, you need to know a React ES6 class component method setState(). This is used to update the internal components state. With React, you do not experience a steep learning curve like you would in other frameworks. Essentially, it’s a view library that was designed to solve one problem. And it does that well! 

React is an innovative place

The building blocks in React offer you the flexibility you need to solve specific challenges. They are easy to exchange if the need arises. The ability to swap in React permits a software developer to experiment with new and acceptable approaches. This makes React a better innovative space.

While Angular provides its own solutions, the React core can be exchanged for other building blocks such as Preact – something which is not possible with Angular.

Unidirectional Data Flow

Unlike Angular, React does not have a two-way data binding. Instead, React works upon the rule of unidirectional data flow, meaning that the process of debugging is less complicated. With React, the child components are inserted within higher-order parent components. Additionally, React offers its users total control over the native HTML elements. This means the React state management can be predicted and easily maintained.

JSX syntax blends well together with javascript

JSX is a React syntax used for component building. It also works well with JavaScript and HTML. React code bears a resemblance to true JavaScript, and it strongly relies on more functional programming principles. JavaScript can compose and manipulate DOMs, and developers can use built-in functionalities such as filters and maps. In this manner, the total potential of JavaScript is used within an HTML code, and this process will result in a rapid development pace.

Angular, on the other hand, does not mix view and logic.

React is powered by a faster engine

When it comes to framework engine comparisons, the engine that powers React is much faster than that powering Angular applications. For instance, to execute JavaScript code in the browser, Angular might need around 5000ms, as compared to React, which requires slightly less than 1000ms. A quicker framework offers a better user experience, lesser time waiting to render elements in the DOM, and a website that responds quickly. 

Lightweight Components

React defines its components in two different ways: ES6 class components and functional stateless components. Although stateless components are functional, they don’t have any boilerplate. This means, developers should use them when they need to get access to the lifecycle methods or component state. By doing so, it guarantees developers that the components are lightweight, small, and reusable.

Functional Programming

Functional programming is a declarative programming paradigm where software is developed by applying and composing functions. It feels more natural working in React and its ecosystem, mainly because of its close resemblance to JavaScript. In React, functions should be defined with no side-effects to make them predictable as they return the same output all the time and are composable – as functions of a higher order can be used to compose them into each other. Software programmers think of React as the leader of functional programming when compared to other JavaScript libraries.


Every developer fancies a good community, and it’s an essential factor to consider when choosing a framework. The React community is highly supportive, and you’ll often get the answers you are looking for. And to top that, React developers have a deep desire for innovation and are constantly experimenting every day, coming up with better solutions. For sure, the larger the community, the better the framework!

Challenges and Risks of Migrating from Angular to React

An Angular to React migration comes with many benefits, but you also need to know that there are a few challenges and risks associated with it. As such, the importance of understanding how you can deal with it cannot be overemphasized.

Without further ado, let’s look at some of the risks and challenges of migrating from Angular to React.

Risks of migrating from a template-based solution

Please note that even though React is quite fast, it will not make your application perform faster all on its own. And what’s worse, if a developer adds it to an existing stack of frameworks and libraries that are not quick, React will most likely make things slack even more. 

However, if you replace the older components with React and take out old libraries, you will probably see a substantial increase in performance.

SEO indexing issues

With the increased need to improve a website’s online visibility, many people are concerned about the SEO score of applications that strongly rely on frontend code. In these scenarios, SSR is adopted. Initially, it renders React code on the server, then gives it back to the user, and reuses it later when JavaScript is done parsing. 

However, you will need to mock some of your APIs on the server. For instance, if you use virtualized lists to render elements that are only visible on the screen, you will need to mock the height of the area visible for the user as the server does not know the end user’s screen height.  The height needs to be set artificially on the server to ensure that the first paint contains data parsed by search engines. But the good thing is that the moment React is done loading and reusing the pre-rendered template, it goes back to normal.

The Right Migration Strategy

Two popular refactoring approaches that can be adopted in general software systems refactoring are the Rewrite and Strangler patterns.

Rewrite vs. Strangler pattern

If you opt for Rewrite, you will start with a brand new application and then copy existing application features using a new framework. It will work incredibly well especially if you are yet to release the application. Without existing users, you will not be pressured to upgrade and maintain it.

Advantages of Rewrite

  • You have a clean architecture that fits the new framework
  • There is no need to build integration bridges between old and new code, so you enjoy high development speed with fewer hassles.

Disadvantages of Rewrite

When you want to offer your app users new features, you will have to write them in the old framework. This is difficult to do because you can’t bring in new app features until it fully copies the existing functionality. Generally, it is a challenging approach that is time-consuming, especially if you already have an app in development. Therefore, in working businesses, you will find that oftentimes, Strangler patterns are used for refactoring.

The Strangler pattern, on the other hand, tackles the refactoring problem differently. It assumes that you replace old components with new ones, taking care of stitches between frameworks. Thus, you gradually remove old code and deliver new features using a new framework.

Advantages of the Strangler Pattern

  • Developers can implement new features using a new framework

Disadvantages of Strangler Pattern

  • Developers are burdened with maintaining the interaction of new and old code
  • Developers have to align the new framework architecture with the old framework architecture, with the possibility to refactor the new framework code too.

Overall, these two approaches have many benefits. A noble option is to use the Strangler pattern, select more significant independent parts and rewrite each one independently before connecting all the parts. You need to figure out how to pick these parts to make the most effective refactoring. 

Angular router as a splitting point for refactoring

When you look at the top-level architecture of the Angular application, you will notice that it’s generally an Angular router that assigns all routing events tasks to Angular components. If it is a medium-sized application, you will probably have a large number of routes that use Angular features as handlers. Every page handled by the router is independent (to a certain level) from other pages. So, in this case, the technique of rewriting every page that corresponds to the Angular route independently will be a noble one. 

This is the general idea behind it:

  • Make sure that you clearly understand your company’s plan for delivering new features 
  • Select the routes that are used for these particular features
  • Set up new react components for every route you would have selected. This will simultaneously refactor Angular into React, and will deliver new features.

Here’s one line of code to turn any Angular component into a React component:

1. Installation

# Using Yarn:
yarn add angular2react angular angular-resource react react-dom @types/angular @types/react @types/react-dom
# Or, using NPM:
npm install angular2react angular angular-resource react react-dom @types/angular @types/react @types/react-dom --save


1. Save a reference to the $injector

let $injector
  .run(['$injector', function(_$injector) { $injector = _$injector }])

2. Create an Angular component

const MyComponent = {
  bindings: {
    fooBar: '<',
    baz: '<'
  template: `
    <p>FooBar: {this.$ctrl.fooBar}</p>
    <p>Baz: {this.$ctrl.baz}</p>

3. Expose it to Angular

  .module('myModule', [])
  .component('myComponent', MyComponent)

4. Convert it to a React Component

import { angular2react } from 'angular2react'
const MyComponent = angular2react('myComponent', MyComponent, $injector)

5. Use it in your React code

<MyComponent fooBar={3} baz='baz' />

You need to know that there is no single way to do the migration from any framework to another framework. Migration is always different depending on a case’ requirements. 

Execution Plan

You can use the divide-and-conquer plan to migrate the forms. Here’s how this can be achieved:

  • Bigger chunks of challenges are divided into smaller ones.
  • If your program has more than100 forms, group and address the common elements at the same time.
  • Create a Component template that groups all similarities that the forms have, then proceed to move them all in one large file. That allows me to test them from a single file, and search and replace becomes easier. 
  • Ensure that all form elements are JSX compatible.

Angular to React Migration Best Practices

  1. Migrate one component at a time– Rewriting the whole front-end can be very risky, as it can prevent you from developing new features for quite some time. It’s always a better option to do it step by step, one component at a time.

Here’s a good example: 

2. Generalized bridge binds ngRedux’s state to React– A generalized bridge component, can allow developers to wrap React components to be used also in the Angular application. Its basis is on the reactDirective from ngReact that executes the basic interactions with Angular.

Here’s a bridge code that adds the state from ngRedux to the React component by default:

import React from 'react';
import {Provider} from 'react-redux';
const wrapProvider = WrappedComponent => ({store, ...props}) => (
  <Provider store={store}><WrappedComponent {...props} /></Provider>
  .factory('smartlyReactBridge', function(reactDirective, $ngRedux) {
    return function(Component, propNames, directiveOptions = {}, otherProps = {}) {
      return reactDirective(
        { store: $ngRedux, ...otherProps }

3. Binding a React component to an Angular component– After porting it to React, render it in the campaign management view. Here’s an example of how it was done:

// @flow
import CampaignLabels from './CampaignLabels.js';

4. Next step is to save the matrices of the Angular app in order to compare with the React version. This includes load time, size of the app, and interactive time.

5. If you are implementing new features that strongly rely on front-end technologies (for example streaming, geolocation or live messaging) you should make it a point to synchronize your client’s state, and it’s stored in structures utilizing the old approach, with the one used in React. This will ensure that a user will get a good experience and not face any UI glitches.

6. Work first on the parts that appear easy to port, once done with these you can then proceed on the more challenging ones.

Angular to React Migration Tools

You can make use of the following Angular to React migration tools in your project: 

.gitignoremake react and angular peer dependencies
.npmignoreadd tests, update docs
package-lock.jsonupdate npm lockfile, again
README.mdupgrade deps, move @types/abc to peerDependencies
index.tsxupgrade deps, move @types/abc to peerDependencies
circle.ymlupgrade node version in circle
test.tsxupgrade deps, move @types/abc to peerDependencies
tsconfig.jsonupgrade deps, move @types/abc to peerDependencies
yarn.lockupgrade deps, move @types/abc to peerDependencies🌅

We Can Migrate Your App from Angular to React

The purpose of every library or framework is to provide developers with solutions that enhance productivity and can adapt to the ever-changing demands in the field. Migrating from Angular to React is a great choice because React has an incredible library that comes with a myriad of possibilities. If you want to migrate from Angular to React, get in touch with Appvales. We will handle the task with the best Angular to React migration tool to deliver the right solutions for you.


Should I move from Angular to React?

Making a decision about migrating your website or app to a different technology seems like a tough one to make. It is very crucial to remember that Angular is a framework and React is a library, and this influences the way we compare the two. A library is just one part of your application and this makes the learning curve very small. On the other hand, a framework is quite big and you will need to stick to their standard way of doing things and you’re constrained to do everything, in this case, the Angular way. The building blocks in React give developers the flexibility to select the ones that best suit a particular project. These building blocks are quite easy to exchange if the need arises. This ability in React permits a software developer to experiment with new approaches that can be taken in by the community. This makes React a better innovative space.

Is it easy to shift from Angular to React?

Migrating from Angular to React can appear seemingly like a daunting task. If done correctly with the right expertise, the process becomes much easier. You need to migrate one component at a time and follow Angular to React migration best practices. Rewriting the whole front-end can be very risky because it can stop you from developing new features. In such a case, seeking expert help from Appvales will ensure the process is as seamless as possible.

Can you migrate an existing Angular codebase to React?

When using Rewrite, you will have to start with a brand new application which you then need to struggle to copy existing application features using a new framework. The Strangler pattern, on the other hand, tackles the refactoring problem in a different manner. It assumes that you replace old components with new ones, taking care of stitches between frameworks. Thus you gradually remove old code and deliver new features using a new framework.

2021 Guide to Health Insurance App Development + Case Study

Over the past few years, we have seen massive technological changes in the healthcare industry, particularly in regards to how hospitals and insurers interact with patients and consumers. According to the 2019 Insurance Industry Outlook, there is a significant rise in people’s expectations for personalization, flexible policies, and services that offer more convenience. 

Today, people are looking for the fastest and most innovative digital solutions for all their needs, and their healthcare demands are not left behind. Insurance companies are also constantly looking for ways to make their services more accessible to a broader range of clients. And a mobile app for health insurance is the answer to both parties.

Creating a mobile health insurance app can be an immersive task for software development companies. The ideal healthcare insurance software should contain health insurance plan comparisons, a capable and accessible healthcare providers pool, claim payment management, etc. These features require high precision levels and expertise to build them.

To get it right the first time, it’s best to entrust this job to a team that can build and deploy it correctly. Appvales is one such software development company with an excellent track record building software for startups and enterprise systems, right from the MVP stages to the final product. With our level of competency and experience, you can rest assured our developers will build you an outstanding mobile insurance software.

Insurance Apps Market Overview

Before we get into the intricacies of insurance mobile app development, we must first familiarize ourselves with the mobile apps insurance industry. In addition, information on mobile health and smartphone use is also necessary during the insurance mobile app development process for a complete analysis. 

Analyzing these statistics will give you more insight into why healthcare insurance software is necessary. They will also inform you of the vast market and potential in the sector.

Here is up-to-date data on relevant industries:

  • According to Statista, there was a 65% growth in mobile health apps downloaded worldwide during the COVID-19 pandemic.
  • Two-thirds of the largest US hospitals offer mobile health apps. 
  • Using mHealth tools and mobile app wearables help 8.74% of patients to cope with their health issues.
  • Because of the pandemic, the US health and the medical insurance industry will see a revenue increase of 6.6% in 2021.

From the statistics above, it is clear that both the health insurance industry and the mHealth sector have high growth potential. Therefore, it’s best to leverage it to gain a  competitive advantage.

Top Insurance App Business Models

Like every other application, your insurance business app has to work with an effective business model. Currently, there are 3 top insurance app business models.

  1. The “Freemium” model:

The focus of this model is on the consumer. In this model, users are given free insurance as a value-added service. Apart from the free offer, this model also provides a premium insurance offer. 

The premium insurance offer must have attractive coverage to compel users to opt for it instead of settling with the free offer. This now serves as a source of revenue for your insurance company. There is also the possibility of running in-app ads and generating revenue from there as well. 

Startup insurance companies typically use this model to encourage new users. Families or users that are just using an insurance management app for the first time will also prefer to use this model. 

  1. The Licensure model:

Here, the insurance company pays the software company for rights to the software for a specified period.

During that time, the company will license an aspect of the software to either healthcare providers or customers. Because your insurance company has total control over the software, any use of it and its features will generate revenue. 

This model generates recurring revenue for your insurance company. Here are the ways software licensure can generate income for your company:

  • Licensing/ selling a service or device to clients: For instance, certain health insurance apps come with wearables that will help monitor the vitals of the customer. Clients will have to pay for the wearable to access that specific service.
  • Selling medications on the app. 
  1. Health Insurance Reimbursement:

Here, the focus is on the mobile app, not the patients or healthcare providers.

In this model, a health insurance management system can integrate a feature that carries out therapeutic services. When this feature of the app is FDA-approved, it can replace a traditional diagnostic device.

For instance, AlivCor ECG Mobile Heart Monitor has been approved by the FDA. Now, it is used by health providers instead of the traditional ECG monitor because it is a cheaper alternative. The care providers will have to pay to use the product, of course.

Now, imagine your insurance app has a feature like that. That means the healthcare provider will reimburse your company every time that aspect is used instead of the traditional device covered by the insurance plan.

Although this model is relatively new, it will cause market disruptions. This is because it focuses on innovation and creating intelligent solutions for the healthcare industry.

Core Features of Health Insurance App

Different insurance apps come with varying features. However, certain core features must be included to ensure the success of the healthcare insurance software. They include:

  1. A profile:

A profile consists of the user’s health information as well as their healthcare ID. You must encode adequate security measures to protect client information during the insurance mobile app development.

  1. Health Insurance Plan Search/Comparison:

The majority of the time, patients are unsure of which healthcare insurance plan to opt for. This is because their choice depends on multiple factors like their budget, the health issue they are undergoing, etc. 

On that note, your insurance web application or mobile application should ensure this decision is easier for them to make. For example, your app should have a search function to enable your clients to browse all possible health insurance plans. In addition, your app should display all the necessary information on each insurance policy to ensure transparency.

It would also be good to include a mini-questionnaire to help tailor plans for the users based on their answers. This is what an innovative app, myOscar, does. That way, patients get to choose the right policy for them.

  1. Claims management:

Another essential feature to include in your mobile insurance software is the ability to quickly make claims without the stress of waiting on a call or standing in a queue. Your app should provide the different claim options so the patient can quickly search, view, and select one.

There should be an option for uploading pictures and signing a digital signature to prevent insurance fraud. Lemonade, another fast-growing insurance healthcare app, even allows the use of videos to submit claims.

There should also be a speedy response to claims, else that lag would defeat the purpose of convenient insurance management. 

  1. Knowledge repository:

Fundamentally, your insurance business app should contain a type of knowledge base that will help your customers become more responsible policyholders. Having interactive content like blogs would be more profitable than static PDF documents.

  1. Connection to a network of healthcare providers:

The ability to simply search for and find an accessible healthcare provider is one of the most significant benefits of the personal insurance apps. However, customer satisfaction reduces when an app doesn’t have a unified and extensive list of connected healthcare providers.

Your insurance software should consider healthcare providers based not only on location but also on other categories such as experience, specialty, language, user’s budget, etc. That way, the app can easily link users to a healthcare provider personalized for their immediate needs.

  1. Billing options:

Renewal and purchase of insurance plans should be easy for the users. Your insurance app should offer multiple payment options to enable users to pick whichever option is more convenient.

myOscar handles its billing solutions by providing various channel options for its users. They can pay:

  • With a debit card or a checking account online.
  • By calling a concierge.
  • By mailing a check
  • In the app, through integrated checkout options.
  1. Appointments management:

Linking healthcare providers to their patients is one significant benefit of an insurance or health app. The app should also be able to manage things like appointments and meetings for the user. It is also necessary to invest in telemedical features like video conferencing, calls, and messaging between patients and healthcare providers.

  1. Virtual branch:

The app has to be viewed as a virtual extension of the insurance company itself. Therefore, contacts and email addresses of insurance agents should be easily accessible to the customers. This is in case they need any assistance with their insurance policy.

In the next section, you will find out that mobile insurance apps should have different software for the three various parties involved. The software for the healthcare provider and patient has similar core features. However, some extra features are necessary for the insurer’s app.

They include:

  • Client information: Insurance agencies should add new users via an app, edit their contact information, and view their billing history.
  • Insurance policy management. When there are updates to standard policies, agents should input the information into the app.
  • Data analytics. It is necessary to include the statistics of users in the insurer’s app. This is so they can monitor trends and analyze data to provide better services to clients. This will keep the business successful and keep customers satisfied.

Types of Insurance Apps in Healthcare

A standard health insurance app offers three services within one software. Or it could be one app split into three different models for the three parties involved in the process.

  1. A patient health insurance app:

For patients, the app must be straightforward to use and understand. During insurance mobile app development, it is best to ensure that the app provides more functions for the patient, aside from purchasing insurance plans. Develop an app that can also serve as a repository of drug information, healthcare tips, and insurance information. 

Below are the roles a mobile health insurance app should fill in the lives of users:

  • A source of easily accessible information on different healthcare providers.
  • A guide to the best healthcare provider to head to, taking specialty and budget into consideration.
  • A simple and transparent insurance provider that they can trust.
  • A means of reducing the high cost of medical bills.
  1. An app that aids healthcare providers:

A health insurance app should be aimed at making the daily routine of healthcare providers more straightforward. It should be a source of necessary patient information so that healthcare providers can make better decisions concerning the patients. It should also help in hospital inventory management.

Other benefits that the app should give to providers are:

  • It should offer telemedicine services, thus helping with virtual consultations with patients.
  • It should have chat options that will enable healthcare providers to collaborate when necessary.
  • It should contain basic medical information on different drugs and diseases.
  1. A process solution to insurance companies:

A well-developed mobile insurance app will be a dream come true for many insurance companies. This is because it is developed to make their job processes easier. Here are the benefits of a health insurance mobile app to the insurers:

  • A means of automating the insurance business process.
  • Enhanced customer management.
  • Superior customer experience with the integration of chatbots and AI technology.

Challenges you would encounter building an insurance app

Despite the many solutions it brings, insurance mobile app development is no breeze. Here are the challenges usually faced when developing one:

  1. Security and privacy concerns:

As with everything that requires users’ data to function effectively, there is usually concern about the privacy of information shared on the app. Due to these concerns, The Health Insurance Portability and Accountability Act (HIPAA) was established in the US in 1996. 

It contains rules that protect sensitive patient data. Considering that health insurance apps will be dealing with PHI, i.e., protected health information, your app must be HIPAA compliant. Any failure on your part can lead to hefty fines and loss of credibility with users.

There are 3 HIPAA rules to protect patient health information:

  • The Privacy Rule
  • The Security Rule
  • The Breach Disclosure Rule

You have to ensure that your insurance app is not breaking any of them. You can do this by following the HIPAA compliance checklist. The four primary requirements of the list are:

  • You must put encryptions in place to protect patient health information.
  • Limit the use and sharing of PHI to the lowest necessary level
  • Have Business Associate Agreements (BAAs) in place with healthcare providers that perform covered functions. Covered functions are simply the activities these organizations carry out that makes them healthcare providers
  • Carry out training on PHI protection and place limitations on who can access patient health information.

Another way of complying with HIPAA is by enabling multi-factor authentication to keep patient information safe.

  1. Regulations:

Besides HIPAA, your mobile insurance app must follow other regulations depending on the region where it is active.

Other regulations exist, such as:

  • The Health Information Technology for Economic and Clinical Health (HITECH) Act:

This is simply more additions to HIPAA in the United States. It was adopted in 2009 when more and more healthcare software was being created. The purpose is to ensure the meaningful use of electronic health records (EHRs). 

  • The General Data Protection Rules(GDPR)

This is the regulation used by the European Union to protect patient data. It doesn’t matter if your mobile insurance app operates outside the EU. as long as you have access to data from citizens of the European Union, you have to ensure your app is GCPR- compliant.

Thus during the insurance mobile app development, take note that:

  • Your app can process information only with the consent of the patient (the personal insurance app user); 
  • Data processing companies must inform the supervisory body and store data during the necessary time only; 
  • All data must be correct, or it will have to be removed or fixed; and 
  • Sensitive data has to be protected from damage or illegal processing. 
  1. Data sharing among patients, healthcare providers, and insurance business app:

Interoperability between healthcare providers and the insurance app has to be seamless. Interoperability in Healthcare Mobile App Development refers to the ability of healthcare organizations to communicate and share medical data in a secure environment.

During the mobile insurance app development, a digital healthcare ecosystem has to be developed by the software team. This would go a long way in providing a holistic healthcare model that all parties can benefit from.

How to Build Health Insurance Software With Appvales

  1. Commence Engagement Process:

This is the preliminary stage, where your company indicates interest in a mobile insurance app. Appvales will provide you with a high-estimate quote, and the purchase agreement is signed.

  1. Formal Commitment to Proceed:

At this point, Appvales explains the requirements for the app to your organization. A project execution plan and schedule are both drafted.

  1. Formal Commencement of Project:

Appvales begins to design and develop the mobile app. Later in this stage, a prototype is ready, and system tests are carried out.

  1. Post-launch Period Commencement:

The app has undergone every test and is almost ready for launch. Finally, both companies agree on acceptance criteria, and a go-forward plan is drafted.

  1. Formal Maintenance and Support Agreement:

Both parties vet and sign the support agreement, and a maintenance request register is opened for the app.

How We Built a Health Insurance App for a Client

Appvales has in-depth experience with mobile insurance app development. Here is the breakdown of our work process:

The team of developers consisted of two standard front-end developers and two back-end developers.

We followed the processes as listed in the previous section on building a mobile health insurance app. We were hitting our goals for each stage and would have achieved the original release plan after five months.

However, the client reversed some aspects of his business model midway. This caused specific unforeseen challenges, which we eventually overcame.

The highlight of the application’s feature was that users were given the ability to create personalized insurance plans and could compare insurance policies. However, if they didn’t find a suitable one, the option to build their insurance plan was made available.

This way, customers didn’t have to plan their funds around an already developed insurance plan. In addition, this eliminates the likelihood of incurring extra costs assuming the plan that suits your budget doesn’t cover some specific features they want.

The app was built with React and Redux and started with a mobile-first style. However, later we also implemented a full-fledged mobile application using React Native.

The server-side and the database were built with NodeJS and MongoDB. We used NodeJS for the server-side because it uses an event-driven, non-blocking I/O model to be lightweight and efficient for server-side applications. We used MongoDB because of its flexibility which encourages scaling, and its built-in security features.

A convenient, practical approach always makes the development process more manageable and makes application support rarely needed.

The pivotal factors in this surge include the fast rise in e-commerce popularity, demand for RFID technology, widespread adoption of smartphones and other mobile devices, and the need to reduce supply chain inefficiencies. These have effectively taken down the reluctance of most businesses to switch from legacy systems and invest in inventory management software development. 

Therefore, the market, which was at 3 Billion (USD) in 2019, is expected to grow at a CAGR of over 5% between 2020 and 2025, reaching 5 Billion (USD) according to Global Market Insights

Source: Global Market Insights

Impressively, it would be no surprise if these numbers are surpassed as the demand for robust software to improve and control the supply chain across the e-commerce and manufacturing sectors is predicted to further fuel the market demand. So, to stay competitive and efficient, companies are now looking to create inventory management software with the help of development companies like Appvales, boasting an excellent track record building MVPs for both start-ups and large enterprise systems. 

That being said, the development process focuses on ensuring the product enables the seamless, efficient tracking of inventory levels, orders, sales, and deliveries. In addition, It can also create work orders, bills of materials, and other production-related documents in the manufacturing industry. However, every software is unique depending on one’s needs. Therefore, to help you communicate effectively with the development team on what you expect, here are some core features that you should consider for your project.

Core features of Inventory Management Software

When starting an inventory management software project, one must inform the development team of the features they need to integrate into their system. These features will determine the solution’s ease of use, efficiency, and productivity, hence, the importance of knowing them and selecting which to include. The most common inventory management system software features include:

Reorder Point 

Stock management software provides the user a product list and the required stock quantities. When the quantities reach a certain pre-programmed point, the software immediately alerts the manager to reorder a predetermined amount of the product. Therefore, the shortage of and excess stocking is prevented.

Asset Tracking 

With this stock management feature, one can use radio frequency identification, barcodes, serial or lot tracking numbers to track their warehouse or store products.

Product Listing

With this feature, one can systematically keep their items by creating each item’s alternative based on its principal attributes. In addition, the feature permits the user to organize their inventory, using essential details like availability, cost, SKUs, and so on. Therefore, this is one feature highly recommended to include in inventory software development.

Barcode Scanning

This inventory tracking software makes use of product barcodes to keep track of them. To eliminate the need for expensive scanning hardware, smartphones can be employed in the exchange of electronic data.

Reporting Tools

Many reporting tools are used to develop inventory management systems’ order history, transaction reports, and total reports. When included in the inventory management software development, these tools let the user create a smooth workflow by providing information on a stock that needs re-ordering, is profitable, and more.

Inventory Forecasting

To avoid having too much or too little stock, one has to decide how much to buy. This feature makes the decision process easier by forecasting how much your type and size of the company would need to purchase. Therefore, one makes the right decisions and protects their productivity and sales.

Inventory Alerts

When inventory levels drop below the user’s preset threshold, alerts are created and sent to them via SMS or emails. This way, one knows when it’s time to restock in advance.

Accounting Tools

Overhead allocation, cost layering, disclosures, measurements, and more are accounting tools that aid the derivation of a more precise evaluation of stock. This tool removes the struggle of manual evaluation, thereby saving time and money while being more efficient.

Raw Material Tracking

This is used in deciding when there are adequate raw materials for more or new jobs in production. Therefore, one can more reliably determine more productive alternatives for the workforce to focus on. Labor costs are also kept in check with this tool.

Inventory Levels for Parts and Finished Products

This ensures the user knows what is readily available and ready for purchase and instant delivery to the client. These could be finished products in the warehouse or in the store.

Automatic Re-ordering

With this feature, reordering stock is automatically done once the minimum limit is reached, ensuring you’re always on top of your inventory.

Integrations with ERP or Maintenance Software

Re-entering information in separate programs can be cumbersome. Therefore, making sure developers integrate with ERP or maintenance software during inventory management software development is critical to the seamless flow of data.

Multiple Location Support

A tool vital for companies with multiple locations that ensures data across all sites is compiled and tracked in one system. This way, one can keep track of the total business stock effectively.

Shelf and Bin Tracking

Managers must know where a particular item is located in the warehouse for access without delay hence the need for this feature. For a personalized experience, your specifications determine the inventory tracking system design.

Order picking support

This feature helps put the customer’s order together in the required quantities before shipment. 

Real-time Inventory Tracking 

With this feature, one can track their inventory anywhere it might be in real-time.

Serial Number Tracking

From the moment an item is received and its serial number recorded in the system, it can be tracked until it is released. When a product is returned, its serial number in the system can be used for verification.

Expiration Date Tracking

This feature allows one to know the expiry dates of products in the warehouse or store. Therefore, one can plan informed which products have upcoming expiry dates. 

Item Images

With this, you can assign multiple images to an item in the warehouse or set one image for quick reference.

Price/ Cost List

This feature allows you to pre-set price levels to items that you can easily quote to customers. 


A third-party logistics feature brings transparency to inventory logistics. This includes trackers and transport analytics which provide users and managers with location and estimated time of arrival information.

Inventory Management Trends:

There are top trends not to miss when one endeavor to create inventory management software that stands the test of time and maximizes on the latest technological advancements. Here are the current top trends in inventory management software development:

Going mobile

A company that integrates mobility into their inventory management software project will:

  • Enhance visibility of all the processes on all levels.
  • Get real-time inventory management.
  • Reduce cycle counts and physical inventory times. 
  • Monitor all procedures effortlessly.

AI and machine learning

The value of artificial intelligence and machine learning in inventory software development cannot be emphasized enough. This is because AI in inventory management enhances process optimization, gathering insights, and making informed decisions. This allows for demand forecasting, cost optimization, maintenance scheduling, and, most importantly, intelligent decision-making.

Computer vision

This technology allows a computer or machine to read and interpret image and video information. Some of the applications of computer vision inventory management include: 

  • Barcode and text label scanning.
  • Labeling, tracking, and tracing. 
  • Packaging inspection. 

Due to its application in these management areas, CV benefits the user through:

  • Stocktaking improvement
  • Human error mitigation.
  • Increase in productivity, and more.


Those who have been following banking, investing, or cryptocurrency over the last ten years may have heard the term “blockchain.” This is a specific type of database that differs from a typical one in how it stores information. Blockchains store data in blocks that are subsequently chained together. The use of this technology in inventory management is forecasted to rise to 54% over the next five years from a meager 5% recorded in 2018. 


Drone inventory management might sound a bit far-fetched. However, it shouldn’t in a world where companies like Google and Amazon deliver products to customers via drones. These devices are taking off in the logistics sector, serving as support for stock management and other tasks. For example, warehouse drones are fast becoming game changers in taking annual inventory, which usually involves stopping all or part of the facility’s activity so that operators can scan all of the items. Drones could free workers from tedious jobs in this operation and enable the warehouse to continue operating normally.

In addition, the use of warehouse drones in manual inventories essentially puts an end to human error and inefficiencies. Drones independently fly around the facility, scanning barcodes, and RFID tags while informing the WMS of their findings and progress.

Therefore, drone use can be beneficial for automatically avoiding stock mismatches and ensuring that warehouse activity continues as usual while taking annual or periodic inventory.

Going to cloud

Cloud-based inventory management systems can be accessed from all types of devices. Also, this inventory management system software is IoT-driven, making it easier to record all the inventory details intelligently and smartly.  IoT keeps the inventory optimized and efficiently organized as all relevant company employees get real-time updates on a wide range of devices. A significant cloud computing advantage is information storage for ease of access and loss protection. 

How to Build Inventory Management Software

To create inventory management software, there are steps that you have to go through to ensure everything goes as planned. Two steps come before hiring the development team and two more after. None of these is any less than the other and should be followed religiously. The steps are:

  1. Write the requirements and user stories.

Approaching a software development team before you know what you require of them and without proper user stories is a waste of time. In addition, the requirements and user stories have to be given in the right way. 


Since there will be changes during the development process, giving, too detailed and concrete requirements is impossible. Instead, the service, function, or feature you need should be stated in a way that leaves room for flexibility without tying these specifications to a solution. Therefore, mentioning the desired achievement without stating how to achieve it is the optimum way of giving requirements. For instance, ‘a flight method’ instead of saying ‘a helicopter’ gives the developers more room to create inventory management software that caters to your needs. Note that to cover all bases, your set of requirements must mention both the functional and non-functional features of the solution.

User stories:

Also known as Epics, user stories for inventory management system are requirements stated from the end-user goal context. Epics are meant to facilitate communication between the client and the developer by expressing requirements more understandably. 

  1. Plan time and budget. 

Reasonable time estimates based on past projects with similar requirements are essential. However, always remember that meticulous application development takes time. As such, patience is vital in the development process. In addition, create a budget to cover the creation of management software that will stand the test of time.

  1. Hire a development team or outsource

Depending on your timeframe, budget, and other factors, you could choose to either hire a development team or outsource. However, fully employing a team of developers would require a long process with HR accepting applications, interviewing, and testing potential employees. This would not be time and cost-effective and also draws your focus from the main drive of your company. Therefore, hiring a team that is already familiar with each other and knows how to create an inventory system is advised. Outsourcing is another effective way to get this done without all the hustle of employing in-house developers. 

  1. Test the system. 

Once the team is done, the system should not be hurried to full use without testing. This helps you familiarize yourself with the software and is essential to see if it functions expectedly and if all features you required were included. 

  1. Maintain. 

Including a maintenance agreement in the development project is vital. It ensures you will not experience severe drawbacks if the system needs a fix, an upgrade, or even an overhaul, depending on your maintenance agreement terms. 

Inventory Management Software Development Cost

No inventory management software project is the same. Therefore, to get an accurate quote, the developers need to have all the precise requirements first. However, the average cost of the inventory management system is an estimated $30K – $50K for an MVP, while a full-featured version should cost you no less than $100K.

How We Built Store Management Web Application for a Client

We made a flawless Tobacco control and reports system for our client. In this section, we shall go into detail on how to create an inventory system in python.

  1. Problem + timeframe

USA governmental institutions and private agencies needed a store management web application for tobacco control and reports. Building this system took about two weeks in the engagement process phase and two for the formal commitment to proceed. The formal commencement of the project, including the design specification, solution documentation; prototype; and system test plan and cases, took three months, while the post-launch commencement period was two weeks. We then started the formal maintenance and support agreement as required of us by the client. Therefore the whole project was done in less than five months.

  1. Features, User stories

The features included were asset tracking, multiple location support, real-time inventory tracking, reorder point, product listing, to name a few. In addition, the detailed yet precise user stories were vital in developing a system with all client requirements. 

  1. Solution + tech stack

Finally, the solution delivered was a high quality, efficient system built by a dedicated software development team using the following stack:

Technological stack:

The store management application development saw Appvales using different technologies, including:

  • Python
  • Django
  • React
  • Redux
  • Celery 
  • Redis/RabbitMQ

The Back-end developers developed the stock management application using Python as the development language. First, the API Framework was done using the Django REST Framework. Then the Database was created by Postgres + PostGIS. Finally, for Background task processing (geoprocessing, import process, etc.),  Celery + Redis/RabbitMQ were used.

The Front-end developers used JavaScript as the development language. The framework was created using React + Redux. DevOps: AWS: EC2 – as API and front-end instance; RDS – database storage, S3 – file storage.

The Application was also dockerized to deploy and run any app on any infrastructure quickly and reliably.

How to build a selling app like Letgo or Offerup

With over 6.4 billion global smartphone users, the exponential growth witnessed in the mobile app industry is expected. At present, most of the growth is coming from selling apps which account for more than 69.4% of all internet users.

Considering that mobile e-commerce sales are expected to reach $3.56 trillion in 2021, a majority of business owners are looking to expand their operations by developing mobile apps. 

Offerup & Letgo are examples of selling apps that have gained a lot of traction in a short amount of time. They are successful marketplaces allowing people to seamlessly trade products. Furthermore, they have received millions of downloads, which is one of the reasons why entrepreneurs wish to create similar selling apps. 

One of the software development companies at the frontline of this technological revolution is Appvales. We are a reputable eCommerce mobile app development firm with a track record of successful end-to-end product development and collaboration with client teams via specialized mobile developers. 

At Appvales, we deploy our resources to build software products for startups as well as enterprises, right from the MVP stages to completion. Read further to discover the essential features of developing a selling app and how we, as a mobile app development company, can help you create a marketplace app.  

OfferUp Business Model

If you want to learn how to make a selling app, we suggest learning about Offerup’s business model.

OfferUp has become a reputable household name. It is a C2C (consumer-to-consumer) internet marketplace where users may purchase and sell things. As a mobile-first company, most of its users access its services through its Android and iOS apps.

Customers on OfferUp can shop for items in various categories, including furniture, apparel, sports equipment, toys, and much more.

For the first five years of its operation, access to OfferUp is free. The founders made this choice because they wanted the platform to compete with giants like Craigslist and Facebook Marketplace, both of which do not charge sellers to list their items. They also sought to attract buyers to Offerup, which could only happen if sellers provided enough inventory to entice them in.

So now, OfferUp stands out with its mobile-friendly software, allowing users to post photos of the items on sale. To boost its credibility, the platform allows you to rate buyers and sellers. As a result, its user base has significantly increased.

The platform has since raised $381 million in total revenue and has around 100 million app downloads.

In 2016, the average OfferUp user spent 25 minutes per day using the app, which is impressive.

How Does OfferUp Make Money?

OfferUp, like any other marketplace, makes money by selling various items and services to its vendors. It began to monetize its services after 2016. 

Let’s take a closer look at how OfferUp generates revenue.

Seller Fees

When a seller on OfferUp sells an item that needs to be shipped, they pay a service fee. Fees begin at $1.99 for each sale or 12.9 percent of the total sale price.

Through its cooperation with the US Postal Service, OfferUp allows sellers to ship their wares to 48 states across the United States.

In addition, OfferUp charges a small service fee for the shipment’s execution. This fee varies by state.

When customers locate anything they want, they may enroll in Ship To Me, make an offer, and pay through the app if the seller accepts. OfferUp can ship items if they are:

  • Under 20 pounds.
  • Not more than 18 inches wide
  • Fit into the predefined box size on OfferUp.
  • Prices range from $2 to $750.
  • Readily available for shipment.

For items that don’t fit these criteria, the buyer and seller can meet in person and transact. OfferUp does not charge any fees for in-person transactions. 

Promoted Listings

OfferUp’s Promote and Promote Plus tools allow sellers to boost their listings. 

A promoted item will appear in the top 50 in the search results.

Users can purchase promotions for a set period, such as two or seven days. Sellers can also purchase so-called Bumps, which propel an item to the top of a feed. So, with each new Bump purchased by other vendors, the listing will slide down the feed.

Sellers can also choose Promote Plus for longer-term or ongoing promotions. Promote Plus is a paid subscription service that allows sellers to promote their items continuously.

OfferUp offers two tiers, namely, Plus-1 and Plus-5. In addition, sellers can promote one or five products at a time for as long as they choose.

The Promote Plus plan starts at $19.99 per month. In addition, OfferUp’s mobile apps allow sellers to cancel at any moment.

If the item does not satisfy these conditions, the buyer and seller can meet in person to complete the transaction. OfferUp does not charge any fees for in-person transactions.

Verified Dealer Program

According to OfferUp, the company’s marketplace currently accounts for more than 10% of all used automobile sales in the United States. 

As a result, the firm launched its Verified Dealer Program in June 2018. Its goal is to boost the visibility of any vehicle dealership that actively sells on OfferUp.

The program offers various advertising features to help dealerships increase sales, such as an AI-powered top lead indication, a click-to-call button, and automatic DMS imports.

The size of the dealership’s business and the number of premium features employed determines the pricing that is available upon request.

OfferUp’s business model depends on charging sellers a commission on sales made and shipped through its platform. The company also makes money via promotional listings and a unique program for vehicle dealerships.

Core Features of Buy and Sell App Like OfferUp

To create a marketplace app, you should know what fundamental elements are needed to make it stand out. As a result, your app will compete with other apps on the market while still providing a unique service to your users.

Users will enjoy the benefits of a seamless purchasing and selling experience on your app if you have these basic features. In addition, you may simply generate more downloads and take the lead in the market because many people share these apps with others.

Registration via social network

This functionality is available in all of the best local selling applications. It improves users’ trust and makes the identity verification procedure easier. Users also won’t have to manually enter the information because the social network selected automatically pulls up their data.

Profile creation

Your selling app should also display user personal information, items for sale, a list of addresses, and cards. Additionally, it must also allow users to erase their profiles and cards whenever necessary.

Search engine

Keep in mind that people carry out location-based searches. So, your app should provide personalized search ranges. Integrating the location feature in your selling app helps your buyers find the nearest vendors when a need arises.

Advanced filters

Advanced filters make the search procedure quick and straightforward. To save shopper search time, segregate everything into categories based on parameters such as groups, price, size, location etc. This option is for you if you have a great app idea but a limited budget. 

Listing Items

If the seller has some identical goods with different variations, each listing can have two options: choose a good from the list (by color, fragrance, and other aspects) or enter one’s own. It would also be helpful to have a sizing chart.

Built-in camera

This function allows you to take images in the app and immediately upload them. The ability to edit pictures, crop them, and modify brightness and contrast would be a welcome addition that the vendors would appreciate.

Built-in chat

One of the most popular and beneficial functions of such apps is the built-in chat. It makes it easier for users to communicate and debate deal details.

Multi-language and currency support

If you want your app to work in multiple countries, it must support relevant currencies and languages.

Push notifications

It’s a cost-effective feature that lets your users stay informed about all novelty, updates, and changes and receive notifications of new messages in the chat.

Offer hot deals

A seller’s ability to offer hot deals, discounts, or coupons is an excellent idea. If you charge for this feature, you’ll be able to earn some more money.

Add categories

Adding categories like top deals and recent offers is an excellent method to encourage sellers to be more honest and increase their ratings.

Scan photo feature

When you want to create a marketplace app, you should consider the Scan photo feature. For example, your app can use this functionality to make suggestions on how to fill in article descriptions and categorizations. 

You may also check the quality of the photographs you’ve posted. Customers complain about the quality of the pictures or that they are fraudulent on numerous forums. Some services address this by canceling a deal and requiring a seller to upload at least one live snapshot of an item.

Inbuilt payment solution

The first time customers use your selling app, it asks for credit card details and phone numbers. Then, users input their emails for verification.

Integrate a safe and secure payment gateway to give your users a seamless experience in accessing your hot offers and bonus packages while reducing transaction time.

Comments and rating

Comments and rating features are essential in every buy and sell website. It helps build customers’ reputations and soft articles according to a seller’s rating. At the same time, the feature safeguards customers against unreliable sellers.

How to Make an App Like OfferUp

Here are the main steps you should undertake to understand how to make a selling app.

  1. Product discovery

First, you need to get your developers to understand your app idea, the problem it solves, the business model, and its target audience.

This step is crucial as it helps you plan your project goals and stages properly, to ensure that you are building the right product.

  • User and market research

When it comes to mobile app development, keep real market issues and customers’ wants in mind to ensure your app’s success.

You might already have a high-level idea of who your users are and what market segment you serve. However, when diving deeper and talking to potential customers, you gain valuable insights into how they see your product. 

This method helps you see hidden pains and gains and get closer to product-market fit.

It is also essential to analyze your competition to evaluate their performance before launching your selling app. Then, from your results, you can optimize your app to deliver a better customer experience.

  • Product road mapping

There is no successful product launch and development without clear plans and an implementation strategy. 

It is essential to create a roadmap of your product from concept to MVP and full-featured product. You can leverage this opportunity to get feedback and consensus on the product’s trajectory and regularly communicate progress. 

You develop top-level strategic goals that drive the primary product themes by synthesizing the stakeholders’ input data.

After creating the product roadmap, your product team can build consensus, outline product goals, and communicate critical needs every quarter.

Of course, this type of roadmap is suitable with the Agile method for product development.

  • Design sprint and prototyping

The design sprint is a seven-day process for designing, creating, and testing customer concepts to solve crucial business problems.

After this process, you will receive a clickable prototype of your product which will help you test your idea and save money on development expenses. You can demonstrate this prototype to your users, investors, and other stakeholders.

At Appvales, we’ve worked with top companies on sprints to help them break into new markets, design new products, and build new features for their users.

  1. UI/UX Design

A good user experience is critical, and your potential consumers will appreciate it. Therefore, as you create a selling app, it should have a simple and easy UI and UX so that users can spend more time on it.

  • UX research

The first impression when a user gets your app begins with the first click. So, you have to create a user experience for your app full of subtle nuances that will make your users fall in love with it. 

The primary purpose of UX research is to inform the design process from the end user’s point of view. 

It is only through this study that you can personalize your product design. Hence, this research tells you who your ideal users are, how they’ll use this product or service, and what they require from you.

Through various observation and feedback collection methods, you better know user behaviors, needs, and attitudes. 

This entire process covers extensive user research as well as basic app functionality. 

Overall, UX research helps you avoid biases because you have insight on how to build a buy and sell website for people who are not like you.

  • Prototyping and wireframing

Now that you’ve established the big picture of user flows and carried out proper UX research, it’s time to start prototyping and wireframing.

Of course, you can’t say whether the user experience is good before you feel it. That’s why you should design clickable prototypes and wireframes to have a clear picture of how the app will look and feel.

These prototypes allow you to test your hypotheses and proceed toward complete solutions.

Prototyping and wireframing follow the golden rule of failing early and cheaply. You can identify and resolve misunderstandings as early in the design process as possible via this process.

  • Brand Identity

Brand identity is what sparks in the mind of people when they think of your app. But it’s so much more than just a logo. 

So, as you create a selling app, go deep into emotions and psychology to deliver a unique brand’s identity that will be recognized and remembered.

  • UI design

After designing the UX, you can add a beautiful look to the functionality. Interface design will reflect your brand’s unique style and touch to stay in the app’s users’ minds and help them navigate intuitively.

In simpler terms, designing a user interface is like telling a joke. If you must explain it, then it’s not that good.

  1. Software development

Software development is one of the most crucial steps in developing that selling app. So, hiring an app development company is a no-brainer because a software company will provide the proper consulting and project management services to ensure you give life to your prototype. 

Below are the steps we follow during the development phase.

  • Mobile and web app development

This is the stage where our developers write code for your marketplace website, using technologies like React, Angular, and Node.js. We also have resources to create both native and hybrid mobile apps for your users to have your app one click away.

  • Quality assurance

This step gives quality attention to every stage of the app creation and delivery to stakeholders and end-users.

To provide a bug-free and seamless experience to your users, adopt the best practices of automated and manual testing. Quality assurance is crucial at every level of the product development process.

  • Security and regulations check

To preserve user trust and device integrity, you have to make your app secure. Therefore, it is essential to adopt best practices that have a significant, positive impact on your app’s security. 

Your app’s security practices should follow the app store regulations Guidelines and all applicable laws.

  • Deployment

Mobile app deployment refers to the process of making the application work on a target device, whether it be a test server, production environment, or a user’s computer or mobile device.

It is essential to start your selling app deployment by testing the waters with a small group of employees. This step allows you to fine-tune the selling app before launching into your entire market.

  • Maintenance

There is no secret to the success and growth of your software. You must always strive to improve your clients’ user experience. Users appreciate even the slightest upgrades. 

As a result, keeping your mobile application up to date is critical. You can keep your maintenance costs down and your customers pleased by incorporating a maintenance plan early in the process and prioritizing upgrades later.

Minimal Team Setup Needed

  • Project Manager

When you bring your app idea to a mobile app development company, you’ll be assigned a project manager (PM) who will act as your assistant and liaison with developers. 

A project manager is in charge of a project from inception to end, ensuring that it is completed according to the agreed-upon budget, timeline, and quality standards.

  • Front-end development team

The front-end web development team is in charge of implementing application designs through coding languages like HTML, CSS, and JavaScript. 

They are responsible for transforming mockups and wireframes into high-quality, high-performance, and responsive mobile apps.

  • Back-end development team

The backend development team is in charge of keeping a server up and running and cloud storage and operational logic.

They also manage payment systems that have access to and securely store data for customers to make transactions in-app and develop the app framework and architecture.

  • Business analyst

Through data analysis, a business analyst will assist in enhancing the selling app development processes. These adaptable professionals help close the gap between IT and business and boost productivity through data-driven solutions.

These insights give you a better understanding of how to make a selling app.

  • DevOps engineer

DevOps engineers simplify the app development process by introducing processes, tools, and methodologies to balance the activities required to swiftly alter an application and the tasks needed to keep it reliable.

  • Quality assurance team

The quality assurance team’s primary responsibility is to monitor every stage of mobile app development to ensure that the design and software meet all criteria. The importance of this team in app development cannot be overstated. 

They perform manual and automated testing to identify app defects and bugs. This task helps the product team fulfill project release dates and stay within budget.

How to Find and Hire Developers for a Startup: A Whole Different Game

There are a lot of traps and pitfalls when hiring for a start-up. But, can you afford any mistakes considering on average it takes 42 days to fill a position and $4,129 per hire? And as if that wasn’t enough pressure, a recent research gate study revealed that oversight in the hiring process is one of the key reasons why 90% of tech startups fail.

Now, you are probably wondering, but what makes the tech start-up hiring process any different from the rest? 

For starters, the role of a developer in a 200+ people corporation is very different from a developer in a 20 people startup. The skills, culture, day-to-day prerogatives, requirements, and habits differ a lot. 

In this comprehensive, we shade more light on the subject and help you dodge the common pitfalls. We leveraged our expertise in the software development industry to research and incorporate the latest and most relevant insights on how to find and hire developers for startup. 

At Appvales, we serve as a boutique mobile app development company and have earned a great track record over the years. We are home to some of the industry’s leading software developers and have contributed to the creation of software and applications for several reputable companies.

Startup Hiring Tips From Experts

Here you will find startup hiring tips from Myles Hunter, co-founder and CEO of TutorMe, and Steve Eakin, founder of Startup Black Belt, on how to hire for a startup company. Myles used these strategies to build a fast-growing and in-demand online tutoring solution, while Steve produced high-profile teams using this tested strategy. One of those teams was later acquired by Amazon at a higher value.

Let’s delve into specifics.

  1. Hiring at an early stage has more impact on the company.

The importance of hiring suitable candidates in the early stages of the company cannot be overemphasized. Hiring the wrong programmer can cause bottlenecks in the software development process, while the right hire will significantly improve productivity. To ensure you employ your right fit, you need to develop a thorough, unrushed hiring process or engage a talent acquisition expert.

A candidate with the vital skills you require but a poor work ethic will derail your plans during the early stages. In addition, you must have a defined company culture and never hire a developer that doesn’t fit into it. So, you should only engage developers who believe in your company’s mission and have a positive attitude. This may require conducting multiple interviews, checking references, and preparing sample test tasks.

  1. Be specific in your job description.

What kind of employee do you want to hire? What qualities, skills, and experience levels should they have? Would they be working on-site or remotely? 

Be sure to include all these in your job description. 

Specifying the job requirements allows you to receive relevant applications, saving time. Furthermore, it shows you where to find suitable candidates. This way, you will be strategic in your search and get a pool of the most qualified candidates.

Since hiring for a startup company is a significant factor in your company’s transition to the growth stage, you need to ensure you’re hiring only the best. The next tip shows you how to identify the best candidates in an interview. 

  1. Build a rapport with the candidate.

The tactfulness required in identifying the best candidates starts from building a good rapport. This is because candidates are more likely to be truthful and open when a good connection has been established. So, to tear down their defensive wall, break the ice by starting with informal chats via a video chat or one-on-one conversations. This way, you get to know each candidate better before the actual interview. 

An interview is not about the candidate alone but also about the employer. Candidates listen to see if your company is a fit for them. Therefore, paint the right picture of your company’s work ethic and culture before and during the interview. 

You can also engage the help of more experienced developers if you’re not tech-inclined. With their insights, draw up a list of words you want to and don’t want to hear, and pay attention to the red flags. Of course, an alternative is to have one of them with you during the interview.

  1. Test them

After identifying qualified candidates for a role, the next step is to test their competence. This test could be a take-home assignment or a sample timed project. 

This part of the hiring process is vital because it gives you a glimpse of the candidate’s thought process, performance, standards, best practices, and how they can solve problems. You also get the opportunity to ascertain how well they communicate and their passion for the job.

You may need to pay for the test project even if you don’t need the result. However, you should never skip this process because one wrong hire can substantially negatively impact a startup.

Let’s jump to the rest of the startup hiring tips.

  1. It’s better to hire more experienced people.

The level of experience is a significant factor to consider when you hire developers for a startup. The wealth of knowledge and expertise of your team ensures you hit the ground running immediately after onboarding. But with junior developers, you get to spend more time and resources in their training.

If you are not a tech person, hiring based on experience is your best bet. It frees time so that you can focus on your core objectives. However, with time and as the team grows, you’ll need to trust their judgment regarding who to hire. Since they know what needs to be done, they know who they need to support their work.

Once you have identified and hired the right people for specific roles, you have set your company on the path of fast growth.

  1. Choose the best candidate.

To choose the right candidate, compare notes with other interviewers. 

If you’re the only interviewer and are having issues with the selection process, it’s best to get the help of a consultant. Doing so gives the process fresh eyes, allowing you to find a suitable developer for your startup.

Developer hiring options for startups

There are three main options available for startups when hiring developers. They can choose to hire in-house developers or engage freelancers or an outsourcing company. However, your decision should be based on your business’s goal, the strategy you wish to adopt, and how it will affect your business in the long run.

Now, let’s consider each of these options, their advantages, and their disadvantages.

In-house developers

Hiring in-house developers can be a good option for startups for the following reasons.

  • You have complete control over the developers you hire, ensuring they fit into your company’s culture and buy into its mission. Also, you can monitor the progress of projects, communicate challenges and discuss details to facilitate the development process.
  • There is more flexibility in operations as you can easily make quick changes and add new features to a project. This also helps to resolve issues and bugs efficiently.
  • There are no logistical, cultural, or language barriers when working with in-house developers. Since you get to pick individual team members, it’s easier to hire people from similar backgrounds. And as they spend time together in the office, it facilitates effective communication and collaboration, which is critical in software development. 

Some disadvantages of hiring in-house developers

  • The process of hiring the right fit for your team is usually slow and demanding. Sometimes, the hired candidate might not be available to start immediately, which is not good if your project has a timeline.
  • Hiring and maintaining an in-house team is expensive for startups. Apart from salaries and bonuses, you get to pay for training, rent, equipment, and taxes. Also, companies get to pay for their staff time off, vacation, and sick days. In a nutshell, companies pay for both the productive and non-productive hours in-house staff put in.

This diagram shows the actual cost of hiring in-house staff for businesses.

  • There is a high rate of staff turnover for in-house developers because of the demand for skilled programmers. Companies that pay more and offer attractive benefits can easily lure your best team members away. Situations like this slow down your project timeline and send you hunting for another talent to fill the vacancy.
  • In the case of an expansion, your current pool of developers may not have the specific skills needed. To hire more developers as a startup can be unattainable in such situations.


The growing need for remote workers has given rise to freelancing and freelance websites as a ready source of workforce for businesses. Most businesses now prefer to engage freelancers to handle specific tasks while their in-house staff focuses on the main functions.

Advantages of hiring freelancers include

  • Flexibility in working hours. Freelancers offer flexible working hours than in-house staff because they work remotely. This affords them more time to focus on the project and deliver it on schedule.
  • Freelancers are cost-effective. Startups can benefit from freelancing because they get to keep overhead costs down. Freelancers are paid either hourly or per project and don’t require bonuses, insurance, tax, or the fee of tools that in-house staff would need to do their work.
  • It is faster and easier to hire a freelancer than an in-house developer. This is because most freelancers are ready to work immediately, unlike in-house staff who must go through the hiring, training, and on-boarding sessions before they commence work. 
  • You only pay a freelancer upon completion of a task or project. This makes them passionate about the work instead of in-house developers who would get paid whether or not a project is completed when expected.

Some disadvantages of freelancers include

  • Many freelancers overpromise and under-deliver. Thus, the quality of their work may fall way below your standards or expectations.
  • They may lack the ability to work independently, and you may have to check in on them regularly. 
  • If the freelancer you hired is excellent, chances are he may abandon your job for another high-paying gig. When this happens, you will have to reassign the project to someone else, which will affect the timeline of your project.
  • There is no confidentiality of intellectual property as freelancers can mishandle our misuse or share your proprietary information with other clients.


Outsourcing provides businesses or startups with the same amount of work and level of quality they would get from an in-house team. In addition, outsourcing companies offer a pool of dedicated and experienced developers to meet the needs of businesses at different times.

Advantages of hiring an outsourcing company

  • It significantly reduces the labor cost for startups and growing enterprises. Outsourcing is a viable option for startups seeking quality talents on a budget.
  • Instead of hiring freelancers, you get a team of professional and dedicated staff working on your project and delivering even better results than in-house developers.
  • When tasks are outsourced, your business has time to strategize and focus resources on essential areas that will lead to growth and improvement.
  • You can easily find resources and engage talents that are unavailable or expensive to maintain.
  • It also reduces the cost of office space, office tools and equipment, and other bills because the outsourcing company uses its resources to work on your projects.

Some disadvantages of outsourcing include

  • Differences in time zone is a challenge startups encounter when outsourcing. One party may be forced to compromise and work outside regular business hours.
  • Businesses may not have complete control over outsourced tasks. This can make monitoring and corrections in the development process difficult.

Roles you can outsource.

  • IT roles like software, app or web development, database development and management, technical support.
  • Hardware manufacturing
  • Business process roles like customer support, data entry, accounting, social media management.
  • Marketing and advertising roles.

Mobile Learning App Development in 2021: Debunked!

Today’s organizations cannot ignore mobile learning anymore. At present, 47% of companies are already using mobile devices to support formal learning. And after embracing mobile learning, more than half of leaders report a 55% increase in their business. Clearly, the use of technology in education and training is swiftly becoming the standard de facto.

According to Statista, the global e-learning market is anticipated to surpass 243 billion U.S. dollars by 2022. And today, nearly 65% of teachers already support open educational resources in teaching, and 63% show interest in the competency-based education system.

Read on to know more about mobile learning app development and how it can help your organization.

What is Mobile Learning?

Mobile learning, or simply mLearning, refers to the process of learning via the internet or network using personal mobile devices such as smartphones, tablets, laptops, and digital notebooks.

MLearning can make our lives easier in a variety of ways, and the rate of adoption of this innovative approach to education has grown exponentially in recent years.

This form of studying grants students continuous access to information, materials, and resources through their devices. It delivers the best visual learning information as well as traditional text-based stuff. Furthermore, mobile learning encourages microlearning, a method that makes studying more manageable and convenient. Learners can read at their own pace, anywhere and anytime.

The usage of a mobile learning app enhances course completion rates and user engagement. According to Tech Jury’s verdict, the mobile learning market is expected to reach a whopping $78.5 billion by 2025.

What are the benefits of mobile learning?

Here’s how mobile learning can benefit institutions and transform e-learning. 

1. Improved Course Completion And Retention Rates

Learning occurs when students complete all instructional content and remember the essential points. However, due to the boring and less engaging traditional learning systems, students aften end up giving up. 

With the advent of mobile learning, nowadays, learning is much more accessible and fun, in and out of the classroom. This consequently leades to increased knowledge retention and faster course completion. 

2. Cost-effective

Building and maintaining mobile applications is now affordable more than ever. While there are costs associated with developing and administering a mobile learning app, there are methods to minimize these costs and make profits.

In-app purchases, ads, and the introduction of premium accounts will generate revenue while also giving students access to learning materials. Although placing premium apps in the app store is common practice, providing free downloads will get more users to install your application on their devices. Then you can integrate features that generate revenue at little cost to your mobile users.

The revenue generated from mobile apps has increased yearly since 2014. The estimated revenue for 2023 is $935.2 billion. Advertisements, in-app purchases, and premium accounts are a good way to get your own share of this lucrative market.

3. Accessibility

Today, virtually everyone owns a device that can download mobile applications. Furthermore, most people now have access to unlimited mobile data or Wi-Fi. This means your e-learning app can be available to nearly all target users in real-time. 

Did you know that education is the third most popular category in the App Store, following only Games and Business?  On Google Play, e-learning is even more popular, and takes second position. Overall, the category has a total share of roughly 9% of the total on both platforms.

Mobile education is easily accessible and fun more than ever. The graph below represents the popularity of mobile learning in app stores globally.

4. Flexibility

The flexibility of mobile apps helps learners to reach study goals despite their busy schedules. They can access classes at any time and schedule a session whenever they have a spare minute. This flexibility is convenient for people’s schedules and learning preferences. For instance, some students like to work in the morning, while others do their best work at night.

Users can always learn at their own pace, thanks to e-learning. You can also provide your students with blended learning that integrate teleconferencing features for synchronous learning that matches what they’re studying on your mobile app.

5. Promotes microlearning

Microlearning, as previously discussed, involves breaking down material into smaller chunks or limiting learning sessions to a few minutes. It’s entertaining and also motivates users to achieve a set of short-term objectives. This type of learning is best delivered through mobile apps. 

Users will only be able to engage for a few minutes at a time, rather than spending long hours trying to digest the information. Push notifications are one of the best features of the mobile app platform. With this, you may remind people to come back and brush up on their skills regularly. This personal touch makes users feel like they’re part of an online learning community.

6. Fosters Collaboration

Lack of collaboration between peers is one of the key issues with distance learning. Mobile learning apps facilitate communication and foster a sense of unity in students. The platform offers learners the opportunity to connect with mentors, teachers, and peers to discuss ideas from anywhere in the world through texting, online forums, and comment sections.

7. Engaging

The core objective of mobile applications is to engage users, and mobile learning apps are no different. Mobile e-learning software allows endless ways to engage with and connect to learners, and because most individuals carry their phones with them wherever they go, they can utilize the app at any time.

Mobile learning apps are built with the learner in mind, and the platform is versatile enough to pique the interest of even the most disengaged students. Visual learning through music, videos, and graphics are ways education application development has helped students study.

8. Personalization

To meet the needs of students, developers incorporate personalization in mobile learning. They allow mobile learning apps to use personal information provided by the user to connect directly with the learner. This way, it is more engaging and enjoyable.

The mobile learning software is also designed to present learners with progress dashboards. Users may also design their own goals and pace for the course, which is a huge plus. They may also be able to select their daily tasks and alter daily reminders to their preference.

9. Multi-device support

After launching your mobile application, you can make the course accessible across devices. This is a great way to expand your digital learning strategy. 

The more your mobile app can reach users across various devices, the more engaged they will be. 

10. Merges best practices and technology

Mobile applications leverage the most up-to-date technology to seamlessly deliver material to learners. Educators and employers are continually improving their ability to teach through these digital platforms. The ability to combine audio, video, and graphics with collaborative tools like discussion boards allows mobile devices to deliver cutting-edge teaching approaches.

Teachers can pre-record lectures remotely using an online video chat app or even YouTube. Interestingly, previous lessons are made available to students immediately on their mobile devices if a course includes synchronous and asynchronous learning.

Types of educational applications

In educational application development, there are certain criteria you must consider, especially demographics. 

Although educational apps have a variety of features and can be enhanced with many learning modules, it is typical to categorize them according to the primary tuition goal for which they were created.

Here are the types of educational applications:

  • Training apps for the classroom – these are e-learning apps that work with a key curriculum, in-person, or an online course.
  • Language learning apps –  mobile applications for learning languages have proved their worth. They cater to various types of students and encourage microlearning.
  • Niche-specific apps – these apps concentrate on a single subject. Higher education levels, such as high school, college, and graduate school, are the most prevalent. The learning apps can also be tailored to the needs of experts in a particular field.
  • Educational apps for school-aged children – this type of app helps kids augment their learning in a fun and entertaining way.
  • Educational gaming apps – gaming apps are fun and interactive, and they help you remember what you’ve learned. For both youngsters and adults, this can be a beneficial tool.
  • Special education apps – they are perhaps the most undeveloped in the mobile learning category. Developing this e-learning app requires a high level of user experience. To ensure success, prospective institutions need to collaborate with non-profit organizations or obtain government financing. 

Top 4 Trends of Educational Apps

Before the rise of mobile learning apps, schools used libraries, and organizations would distribute their training through classroom sessions, textbooks, and legacy LMSs.

Recent major world events in this era have forced us to evolve beyond the legacy systems and adopt NextGen training platforms and mobile learning apps. Schools, universities, and coaching centers will need to shift their focus towards online learning to continue their business operations. 

Let’s analyze the main trends in educational mobile app development that will reshape the scopes for e-learners across the academic and corporate space;

  1. Artificial Intelligence (AI) and Machine Learning (ML)

Artificial Intelligence is prevalent in almost every sector today. When it comes to mobile technology, developers have successfully integrated AI and ML into app features and functions. With intense algorithms of Machine Learning capabilities, eLearning has emerged as the new domain for learners to change the perspective of the traditional cumbersome learning methods.

Through AI, mobile learning apps leverage the use of voice assistants, such as Siri or Alexa, to personalize User Experience. The most important benefit of today’s mobile learning apps is that they prioritize student and instructor wellness right away by eliminating teacher burnout and student worry.

AI helps deliver customizable virtual tutoring to students/employees. As a result, apps can better predict student behavior and provide learning content and training recommendations based on previous behaviors.

Experts have predicted that half of learning management tools created by education software companies will be enabled by AI capabilities by 2024.

  1. Gamification and training in a gaming format

Educational applications designed with gaming in mind ensure a high degree of participation and positive reviews.

To stand out from the competition, you can blend 3D effects in your mobile learning application development project. You can also implement a 360-degree video integration for a balanced learning experience using mixed reality or Augmented and Virtual Reality. This way, learners can achieve the classroom experience from anywhere and at any time.

  1. AR, VR & Wearable Devices

Wearable technology is the latest trend that takes the eLearning experience to the next level. These smart wearable devices can deliver better and comprehensive support for corporate training. Their training simulations immerse learners into a story, allowing them to understand the lessons better and apply them in real-time

These technological trends have benefited both academics and businesses, making eLearning apps a vital add-on that allows for better student and staff training and knowledge retention.

As time passes and new technologies are introduced, AR and VR software are becoming less expensive, faster to create and therefore easily accessible.

  1. Micro-Learning

Microlearning has become the new norm in the 21st century. This learning method is best fit for learners who don’t have enough time to devote to studying at one go. Breaking down study outlines makes them more appealing to a broader range of learners of all ages and vocations.

This adaptability of this approach allows educational application development companies to use a variety of learning applications with success. The best way to use this strategy effectively is to combine it with traditional ones. However, this depends on the content, purposes, and structure of your app.

Core features of mobile educational app

If you are planning to develop an educational app, it’s time to think about the features of your mobile service. Several mobile apps claim to provide the best features, but only a few succeed over the rest.

These fundamental features make your educational app stand out from the crowd:

User profile

For identification purposes, each user of your educational software needs a profile, where they will store information about their learning progress. It’s recommended that you provide a simple and easy-to-navigate interface that will be easy for new learners to onboard.

Progress Tracking

Here you can add to students’ and teachers’ dashboards. This will aid in keeping track of the progress accomplished as well as making the learning process more insightful and effective.

Social network integration

More and more mobile applications are now integrated with social media. This comes with several perks, including allowing the user to easily register/sign in to the app using a social network profile or share his successes with friends and on social media.

Interactive Content

With increasingly and chronically short attention spans in today’s generation, making your app interactive is critical. For starters, add the following:

  • Quizzes
  • Reward-based discounts;
  • A short and interesting video clip
  • Incorporate engaging facts and interesting statistics to keep the learner’s attention;
  • Understandable content worth reading.

Push notifications

This is yet another feature that every current mobile app must carry. Push notifications are an easy approach to remind users of important tasks while also increasing their engagement. 


Reviews can be negative and even unpleasant at times, but they’re also a great opportunity to improve your app by listening to what your consumers want.

Scheduling system

A systematic approach to learning is required for effective learning. As a result, when considering how to create an educational app, keep a convenient scheduling system in mind. Split the learning process into a few logical stages and provide the user with a tool to help him plan his training.

Search system

This feature makes it easier for the user to browse within the e-learning app and easily find the information they need. And the quicker the user achieves the desired outcome, the more likely they are to continue using the educational app.

Offline Mode

The availability of a stable Internet connection can pose a great challenge, particularly in developing countries.

As a result, the offline mode feature allows students to use downloaded lessons to continue learning even when there are connectivity issues. This keeps their interest in your app alive, and they’ll return to it whenever they need information. Continuous learning even offline shows that you are considerate and helps to keep users engaged, they won’t see a need to look for another one that offers offline access. 

Mentioned above are some of the educational app features. However, note that you have complete control over how you develop and supplement the features of your mobile e-learning software when working with Appvales.

Best 5 Recommendations to improve educational mobile app

  • Make learning active, intuitive, engaging, and meaningful

It’s no longer sufficient to have students passively receive information from an expert while taking notes, as it was done before. As a modern tutor, a mobile app for education must serve as a coach and a facilitator of instructions, not just a source of knowledge.

Active learning implies that students actively participate in the learning process, engage in it, and improve their performance as a result.

An intuitive and engaging design is a strong component every modern educational app must possess. Every user should be able to interact with the system without difficulty. If users do not understand or find the application difficult to use, they will most likely delete it. To make your app more engaging, you may also publish content that motivates your users.

Meaningful Learning means that learners are aware of why they are studying a particular subject and what they will achieve as a result.

  • Project-based and problem-based learning 

Education that is built around projects and real-world challenges is significantly more rewarding than simply memorizing facts. It is more efficient to incorporate features of specific concerns instead of standard theoretical and abstract models.

  • Cooperative learning

Learning becomes easier and far more effective when there is someone you can turn to for help or just share your opinions on the subject and have a little critical thinking session. So, working in a group improves the attention, involvement, and acquisition of knowledge. Adding social networking features is a big plus to your mobile learning app.

  •  Gamification 

Gamification of an app is also critical for attracting more users and providing them with a positive user experience. Students are always fascinated with electronics and games, thus, they learn more when they participate in entertaining and game-like activities. 

Using digital badges encourages learners to take on new challenges in their studies and progress to the next level. 

Gamification aids a student’s cognitive development while also increasing the app’s degree of engagement.

  • Personalization

Personalization is vital in mobile apps as it improves the user experience. In the case of educational apps, the intended audience includes learners of all ages. That means a tailored experience that engages users is critical to the success of an educational application.

For starters, ensure that the application responds to the user’s study approach intuitively and if there are questions, that they are answered promptly and tailored to the particular user.
