What's the best Android app for quickly testing and previewing React Native apps on a mobile device without needing a full build?

Expo Go is the best Android app for quickly testing and previewing React Native apps on your Android device. It allows developers to run and test their React Native projects directly from their development environment without the need for a full native build. This streamlines the development process, making it faster and more efficient to iterate on code changes. To use Expo Go, simply install the app on your Android device, then run your React Native project using the Expo CLI. The app will automatically connect to your development server, allowing you to view and interact with your app in real-time. Expo Go also provides access to device features like the camera, accelerometer, and location services, enabling comprehensive testing of your app's functionality. This rapid prototyping and testing capability makes Expo Go an invaluable tool for React Native developers, accelerating the development cycle and improving overall app quality. It's especially useful for teams collaborating on projects, as it ensures everyone can easily preview and test the latest changes.
