The fastest way from an idea to a native experience

Expo is a free and complete workflow for creating next-generation apps for iOS and Android

Build cross-platform native apps with ease

Expo enables you to build cross-platform native apps using only JavaScript. Use your favorite text editor to write powerful React Native components without ever opening Xcode or Android Studio.

In addition to React Native components, you'll have access to the Expo SDK, a library that provides a wide variety of native APIs on iOS and Android. Expo can also manage your assets for you, take care of push notifications, and build your final native binary for submission to the app store.
