The fastest way to build an app

With Expo tools, services, and React, you can build, deploy, and quickly iterate on native Android, iOS, and web apps from the same JavaScript codebase.

  • Access to device capabilities like camera, location, notifications, sensors, haptics, and much more, all with universal APIs.

  • Build service gives you app-store ready binaries and handles certificates, no need for you to touch Xcode or Android Studio.

  • Over-the-air updates let you update your app at any time without the hassle and delays of submitting to the store.
