Expo

The fastest way to build an iOS and Android app.

Expo enables you to build cross-platform native apps using only JavaScript. Expo provides a native runtime with a wide range of native APIs and components exposed to you right out of the box. We combine that with APIs already included with React Native, so most people only have to write JavaScript to build their native apps. In addition to React Native components, you'll have access to the Expo SDK, a library that provides a wide range of native APIs on iOS and Android. Expo can also manage assets for you, handle push notifications, and build your native binary for submission to the app store.
