React Native allows you to build native mobile apps using JavaScript and declarative UI components. The components correspond to the native UI components of iOS and Android.

One code

So, in development for both platforms, we can use Javascript instead of e.g. Swift and Java. This is the biggest advantage of React Native, and thanks to this feature we’re able to share the code between both mobile platforms. This is why you can use the code developed for iOS on Android also. Of course, you’re not able to share the whole codebase, because you use native modules for specific platforms. Still, with React Native you can significantly reduce development time building an app which will be used on both iOS and Android.

One team

Having one team for both mobile platforms gives you flexibility in creating and managing the team. One lead developer in place of two in native approach. As a result, you can have a smaller team that is less costly and easier to manage. Especially, when you decide to simultaneously develop a web app using React.js. You can share some parts of the code between three platforms instead of two. Android, iOS and Web. Then, you can use the approach to have separate modules based on features instead of a specific platform.

Faster results

React Native is a real alternative to native mobile app development. We’ve trusted React Native with one of our mobile apps that took 1.5 months to develop. Based on our experience we’ve been able to estimate that using the native approach would have cost us 0.5 months more, which equals 33%. Summarising, shorter development time, reduced manpower and an easily manageable project are good reasons to consider React Native for developing your next mobile app for both iOS and Android.
