It was the year 2015. The digital world was not doing as well as it is doing today. The community of web wizards were particularly distressed. There were many hassles in their way to technological advancement. But one hassle bothered them the most – they had to create different codes for different platforms for a single application.
Life was devoid of any hope. But then something spectacular happened. The greatest of the great, Facebook, invented a cure for this problem of the web wizards. It was React Native – an open source framework that enabled the use of a single code for web, mobile, android, or iOS.
The wizards readily converted their existing mobile apps to React Native. Some started creating new ones with it. With its Midas’ touch, React Native transformed the digital world forever, for good. To all the web wizards out there, who have not used React Native yet, what are you waiting for? Just try making an app with React Native or convert your existing mobile app to React Native. We are 100% percent sure that you are going to do so right after you finish reading this blog.
What is cross-platform development?
We are well aware that React native is the talking point right now. However, we can not understand it thoroughly if we skip discussing what cross-platform development is.
Let’s assume you are a developer who has an advanced proficiency in Java language and refined experience in making apps for the android operating system. It is safe to say that you can easily build powerful android mobile applications.
But if you were to build the same application for the iOS operating system, things won’t look as simple as they looked earlier. You will have to learn Swift or Objective-C, gain a working knowledge of the iOS operating system and then create another codebase for the same application in Swift or Objective-C. Ages will pass, surely.
All you have to do is to write a code in one of these languages using the underlying structure of a cross-platform framework and boom! You have an application that runs smoothly and native-ly on multiple platforms without a single hitch. We can not think of anything even slightly superior than cross-platform development right now.
What is React Native?
If you want to build a mobile application that runs effortlessly on android as well as iOS devices, React Native framework is the essential key. It is an open-sourced framework available on Github. Therefore, accessing it is not at all a hindrance.
You can use its Java Script library to fetch the already-written code to build and add UI to the framework. If you want, you can always access some external UI library, only if they are compatible with the React Native framework.
The history of React Native framework
There is hardly any doubt that React Native framework is the present and the future of the mobile application development domain. Let us take a sneak-peek into the history of React native before we move ahead.
- It all began in the year 2011 when FaxJS came into existence
- FaxJS was a mock-up for a sophisticated framework for web applications that Facebook was in desperate need of
- In the very next year, FaxJS evolved into React Framework
- In 2013, React became an open-sourced framework, i.e. anyone can use it and modify it to build their websites
- In 2012, Facebook was determined to release a mobile application
- Facebook tried using HTML5 for rendering mobile applications, but failed miserably
- Doing so with the web-based framework posed many hurdles as mobiles and computers have very distinctive differences
- With a highly talented team, Jordan Walke of Facebook came up with React Native in the year 2015
- React Native became a framework for developing mobile applications and became open-sourced that very year
- React Native has not looked back since then and is evolving year after year
How does React Native framework work?
If you want to get the basics of the working of React Native framework, you have to understand it in terms of domains.
In React Native framework, there are two distinct domains –
- The other domain is built of native threads
The React Native framework is fundamentally a bridge through which information is exchanged between the two domains and tasks are accomplished on the mobile app.
Therefore, converting your existing mobile app to React Native is a very easy task because of the bridge approach.
What mobile apps have been developed using React Native framework?
The applications are one of the biggest hits in the mobile app development domain. They are the critical testimonies for one of the greatest inventions of developer-kind which is React Native framework.
Why use React Native App Development Services?
Why would you not, when you already know that so many hit and super-hit mobile apps have been made using the one and only React Native framework? Nothing other than the working application of the framework can be the biggest testimony to its success.
Last, but not the least, and definitely not so unobvious, React Native framework is going to significantly cut short your expense sheet by enabling the development of android as well as iOS applications using just one codebase. A huge reason to celebrate!
When to use React Native for Mobile App Development?
We have lined up below all the different contexts in which choosing React Native framework is the most sane decision you can ever make for your app. Take a look –
- React Native should be your first choice in case your potential mobile app does not rely upon the peculiar features of a specific operating system
- Obviously, it would take far less time and efforts to develop a mobile app using React Native when your website has been created using React
- If your mobile app has a simple and sweet design and involve no tricky animation to design, trust React Native with closed eyes
- Do not overthink and just go for React Native when highly scalable enterprise apps are in question which needs more than frequent upgrades

What are the benefits of using React Native Framework?
- Many Platforms, One Solution
- Intuitive User Interface (UI)
- Huge Community –
- Quick Reload –
- Big Money Saver
Uncountable, if you ask us. Who would not want to convert their existing mobile apps to React Native framework? We doubt that there would be any. Only the name of React Native echoes in the air when we talk of mobile app development. The reason is not one but many, which we have listed below –
Many Platforms, One Solution –
Let’s just talk about the obvious reason first. With React Native framework, you only need a single codebase for your iOS as well as android devices. No need to squander time, money and developers into writing different codebases, when your mobile application can function well with one on different platforms.
Wait, wait! If you have a web application also made using React Native framework, your development work for mobile is approximately ninety per cent already accomplished. Just sit back and relax!
Intuitive User Interface (UI) –
The React Native framework follows a component-based approach when creating UI for the application. What does this mean to you?
Huge Community –
Suppose you are writing code for mobile app development. Suddenly, you stumble upon a glitch in the framework you are working on and you can not find a way to fix the glitch. You need help but you do not know anybody having an advanced knowledge of the programming language or the framework. What do you do?
If React Native is the framework you are using to build your mobile app, then there are thousands of developers you can turn to. React Native has a large support tribe. The tribe is always ready to help you out and build your application.
Quick Reload –
No, you need to rebuild your app after you made some changes to its code for the UI. Atleast, you do not have to if you are using React Native.
React Native quickly reloads the app and allows you to see changes as you make them. You save plenty of your man-hours and brain cells because of React Native’s quick reload option. Also, compiling becomes a ducksoup because React Native allows you to reload only those areas which you have modified.
Big Money Saver –
This point is really an extension of the first point and demanded a special mention. If you are building an app or converting an existing mobile app to React Native, you are an entrepreneur for sure. For an entrepreneur, money is a limited resource.
When you use React Native, you use one code for multiple platforms. You do not need a separate team of developers for a separate platform. There you save money! A lot of it. Time is also money for an entrepreneur. You get to spend less time and your application reaches the market early. The shorter Time to Market (TTM) is a big-win situation for you.
Do we need to say more? We bet that we do not. We are sure that you are persuaded enough to convert your existing mobile app to React Native or just start with a new one.
Things that React Native allows you to do While Converting into Android Applications
A lot many things, if you ask us, to pull off an app development process that is no less dynamic and seamless. For your reference, we have listed a few of them below –
- Code Reuse –
How dare React Native framework claim to call itself a cross-platform app development framework, if it does not allow the developers to reuse the code developed for iOS app to develop android app or vice-versa?
In addition to allowing reuse of the code of a mobile app to migrate to iOS/android, React Native also enables the developers to use almost ninety percent of the React based website code for conversion to React Native based mobile apps.
- Hot and Live Reloading –
Nah! You do not have to eyeball the screen for infinity as soon as you make a single minor change to your app-in-progress. At least, when you are building an app using the one and only React Native framework.
React Native has two absolutely wonderful features – hot reloading and live reloading. As soon as you modify a part of the app, you can reload that particular part using hot reloading and the entire app-in-progress using live reloading (very important!) in no time.
- Quick Update-
Having an app store as a mediator between you and your users, when loads of updates are lined up, could cost you a lot of time and competitive edge.
But do not worry! Here comes React Native with code push, which allows you to modify your app and make those modifications directly available to your users without the intervention of the concerned app store. Believe us when we say that you save plenty of your precious time with code push.
- Third-Party Plugins –
A plugin is simply an addition to the software to enhance its functionality and React Native framework does not have any. However, the framework allows you to readily use a third-party plugin for your React Native app.
- Native UI Design –
You already have a very clear idea that React Native framework harnesses the dynamic ReactJS library. You already know that the ReactJS library uses a component-based approach that speeds up the designing process.
But what you do not know is how React Native framework allows you to blend the ReactJS components with the native UI components to create a mobile application with a very native look and feel.
Do we need to say more? We bet that we do not. We are sure that you are persuaded enough to convert your existing mobile app to React Native or just start with a new one.

Frequently Asked Questions to Convert Your Existing Mobile App to React Native (Android or iOS app to React Native)
- How is app development different for iOS and Android using React Native?
There are some significant differences between the React Native app development for iOS and android. We have explained them briefly below –
- As far as app testing is concerned, React Native-based android apps can be tested on Windows as well as Apple devices.
However, testing a React Native-based iOS app on Windows is not at all probable because there has not been a testing tool designed to test iOS apps on Windows.
However, manual configuration is not at all required in the case of the React Native-based iOS applications.
- It is known that iOS follows a minimalistic approach with regard to UI design, whereas Android has an entirely opposite approach.
The difference between the design philosophies of iOS and android can be encountered during the UI designing process and have to be taken care of by the developers to maintain uniformity.
2. Which one is better for app development – React Native or Flutter?
It may be difficult to determine the better cross-platform app development framework for your app. You can look at the key differences between them and decide accordingly –
- When compared to Flutter, React Native is endowed with more number of packages which renders it a unique dynamism
- Flutter has its own large collection of widgets that may or may not be adaptive, whereas React Native uses UI elements from a variety of libraries that are mostly platform-compatible
- Owing to its invention much before Flutter, React Native enjoys support from a large community of developers and has less number of unfixed glitches as far as comparison with Flutter is concerned
- As far as UI design is concerned, Flutter does not support 3D designing and animation as it is based on a 2D graphic rendering library, named Skia. However, React Native supports both 2D and 3D design elements
3. Which category of apps can be developed better using React Native?
We have defined below the app categories to which React Native app development will perfectly suit –
- React Native framework is best for those apps who will function for a very short span of time, but have to be urgently developed
- React Native app development is best for developing minimum viable products (MVPs) that require very minimal designing and development
- When it comes to developing e-commerce apps with very systematic architecture, React Native is the best framework
- Again, the development of short-term mobile apps for any sort of events, in order to circulate information, can be best done via React Native framework
- When you need to develop an app which has a very rationalised front end, nothing is better than React Native framework
4. Why convert a react web app to react mobile app?
You should definitely convert react app to react native because –
- Obviously, with so many people using smartphones, it is a prudent move to convert your react app to react native
- A react native mobile app is more likely to engage its consumers and retain them into using their mobile applications for longer, which would be good for your business
- With a react native app, you are more likely to give your consumers a very native mobile app experience
- In mobile apps, you have the option to remind your customers of your presence via frequent push notifications
