Six React Native Apps Worth Watching in 2021

Five years ago, in 2016, React Native was presented to the mainstream audience. Released by Facebook and based on already popular React, the framework made a massive impact on the development world. React Native’s way of creating native mobile apps for multiple platforms using only one JavaScript codebase took the world by storm back then, and still is relevant today. Let’s shortly examine six apps built with React Native worth following in 2021.

1. Coinbase

According to their own account , rewriting the whole Coinbase app in React Native started out great, with everything going smoothly until more features were added. That’s when issues with performance, particularly on Android, started. The development team later found out that a library they used caused unnecessary re-rendering, slowing the app down. After finding the root cause of the issues, they managed to reduce the total time spent rendering by over 90%.

2. Flipkart

They started using React Native back in 2016 to ease the development effort, back then heavily divided to create every feature for every platform Flipkart was on. One codebase, access to each system’s native components, and ability to send the JavaScript code over the air seemed to resolve the challenges the company faced. Today, Flipkart developers use React Native (and React-Native-Web) in combination with native languages to unite the best of both worlds and share their React Native journey online.

3. Nerdwallet

In a recently featured story, Nerdwallet developers explain their decision to develop their app with React Native and why they stick with their decision up to this day. By 2016, the Nerdwallet website was already rewritten from an old PHP code to an ecosystem of 12+ separate apps built on React, among others. But the only mobile presence they had was an iOS-only app that connected users with their financial advisor via chat. With some previous knowledge of React and impressive React Native use at company-level hackathons, the Nerdwallet engineers decided on choosing React Native to create their brand-new mobile experience.

The big advantage of choosing React Native was the ease with which web developers using React became effective in React Native code. It worked in the other direction too, and Nerdwallet could reuse a lot of mobile application code on their website. For example, now both the mobile app and web app share the same context-based analytics infrastructure.

4. Foreca

In 2018, Foreca decided to invest in a big mobile app update. Up to this day, the Android and iOS apps were created separately in native code, meaning they were basically different apps, both in terms of functionality and customer experience. To unify that experience efficiently, the development team chose Facebook’s React Native.

Although they met their fair share of challenges during development, including the need for quick post-update fixes and management of accumulated dependencies, Foreca is still satisfied with switching from two native codes to one RN codebase.

5. Guild

Choosing the right technology stack was a fantastic way to achieve a balance between performance and cost. With the recent increase of public interest in WhatsApp alternatives, Guild is definitely worth observing in 2021.

Writing about React Native without mentioning Facebook would be impossible, but when it comes to apps to watch in 2021, the app to watch from Facebook’s family of products is definitely Instagram. Since 2012, when Facebook bought the app, it changed in a lot of ways and introduced various new features. This continuous change is in part enabled by React Native. Instagram developers started using it back in 2016 to accelerate its development speed by allowing code reuse. Since they integrated React Native to an existing native app, instead of rewriting the whole thing from scratch, the company encountered unique challenges on its way.

With fresh features, like the COVID-19 Information Center and Live Rooms feature debuting in early 2021, Instagram feels fresh again and will make some more waves in the current year.

React Native apps, mobile and desktop ones, are here to stay. Not all developers are still in love with the framework, but on the other hand, the collective knowledge vastly expanded, with more issues and challenges being documented regularly, since React Native launched in 2016.
