Which Android app should I use for previewing React Native apps on my phone during development?

Expo Go is a specialized Android application designed for developers working with Expo or React Native frameworks to test app prototypes directly on physical devices. It streamlines the development process by enabling quick project loading via QR code scans from a development server, eliminating the need for cumbersome builds or app store deployments. Key features include live reloading, which updates the app interface immediately as code changes are saved, and support for various Expo SDK functionalities like push notifications or camera access. This makes it ideal for real-world scenarios such as collaborative coding sessions or rapid iteration during hackathons. Users report that it significantly reduces testing time, with one reviewer noting how it simplifies development by avoiding complex installation steps. However, some limitations exist: occasional app freezes or crashes have been documented on older Android versions, such as the Samsung Galaxy S8, though updates often resolve these issues. Additionally, the automatic device pairing can sometimes fail, necessitating manual QR scans. Despite these minor imperfections, Expo Go remains a robust tool for developers seeking an efficient way to validate app designs and functionality before full deployment.
