Expo

Expo is a developer tool for building rich interactive experiences with JavaScript and React Native directly on your Android device and computer. Start coding immediately without complex setup—leverage your device's native capabilities to create and test applications in real time.

Build with camera integration, background location tracking, audio and video playback, and SQLite database support. Each feature is accessible through a straightforward API, letting you focus on what matters: crafting engaging user experiences. Test your work instantly on your device as you develop, catching issues and iterating faster than traditional workflows.

Designed for developers who want to experiment, prototype, or ship production apps using JavaScript and React Native, this tool streamlines the development cycle from concept to deployment. Some programming experience is recommended to get the most from Expo.
