Native applications are developed specifically for mobile or smart devices. There are two camps: Android, which uses Java, and iOS which uses Swift/Objective C.
The benefit of native apps is that they provide a very smooth user experience, are high-performing and allow an application to have continuous engagement with the user. React Native allows for apps to be developed across the two camps without having two completely separate source codes.
How it’s used
React Native apps are practically indistinguishable from true native apps. They demonstrate excellent performance, with only a slight variation to a native app. This can be attributed to the fact that React Native apps are able to take advantage of the graphics processing unit (GPU) of a device. They provide a superior user experience to hybrid apps (web applications within a native app shell).
React Native uses components to accerelate the development process. Because only one team is required to create a React Native app, this means that development time is potentially halved.
For startups and most businesses, a React Native app is a time and cost-efficient way of getting their application on a smart device (barring a web responsive application).
