React Native
React Native is Meta's framework for mobile apps: a single codebase for iOS and Android instead of two separate developments.
React Native is an open-source framework, released by Meta in 2015, that allows for the simultaneous development of an app for iOS and Android. Instead of two teams for two platforms, one team writes JavaScript, yet the app is still rendered with true native elements.
Typical projects include customer apps for e-commerce, employee apps, and MVPs for startups. Its strength lies in the vast React talent pool. Developers with React web experience can build their first app without needing new specialized knowledge, often leveraging the Expo toolkit.
Google's Flutter is its direct competitor and often smoother for complex animations; FlutterFlow even offers a no-code entry point for it. React Native's weakness: for hardware-intensive functions, native rework in Swift or Kotlin becomes necessary.
It's the right choice if your company needs an app for both platforms and lacks the budget for two separate native developments. Before committing, honestly assess whether a good mobile website would suffice, as a bad app can do more harm than no app at all.
