Advantages of React Native

Native UI look and feel

For end-users, there is no obvious difference between a React Native app and a native app. This framework delivers a platform-specific UI for both iOS and Android that looks and performs like a native one.


The framework offers a unique benefit of using the same code for developing applications that run on both iOS and Android platforms. It is the most significant advantage of React Native.

Over-the-air updates

Over-the-air updates are a strong point of React Native. This feature allows the delivery of new versions of the software to mobile devices wirelessly without going through the usual review process.

Open source

React Native is an open-source framework. It means that developers can utilize this framework and its libraries literally for free.

Why React Native is the best framework for your mobile app

React Native allows you to create apps running both on iOS and Android without compromising costs and quality. It is also suitable for projects of various complexity. React Native APIs call Objective-C (for iOS) or Java (for Android) for rendering the components of the UI. Therefore, despite being a cross-platform mobile framework, it retains the actual look and feel of the application, similar to a native application. Moreover, the development with the usage React Native is cost-effective because the same code can be used for both platforms.

We wanted to implement a new education platform that offered online courses in finance. The scope focused on the implementation of multiple user interfaces. UpsilonIT used React, GraphQL, and GatsbyJS. UpsilonIT had strong coding skills. The app had a clean codebase and complied with all specifications. They complied with our requirements for the UI. We communicated daily via Slack.

Upsilon’s work was always on time and met all customer expectations. Their team had an ease of communication but what was the most impressive about them is the integrity and work ethic of each member. We had a business manager, a lead architect, and a mix of senior and regular engineers. The workflow was extremely effective - the teams had a regular cadence for communication.
