Expo Go

What Expo Go does

Expo Go is an Android companion app for developers building mobile experiences with Expo, JavaScript and React Native. It lets you open and test projects on a physical Android device while you work from a computer, making it useful for checking layouts, interactions and device behaviour without creating a separate app package for every change.

Who it suits

This app is aimed at developers, learners and teams experimenting with React Native projects. Some programming experience is recommended, since Expo Go is a development tool rather than a general-purpose app for everyday users. It is also useful when a project needs testing on real Android hardware instead of relying only on an emulator.

Features available to projects

• Run JavaScript and React Native experiences on an Android device.
• Test interfaces built around interactive gestures and graphics.
• Work with device capabilities such as the camera and background location.
• Experiment with audio, video and SQLite-backed app data.
