Apps are important in today's world. Users like apps that are small, especially in markets that use pay-by-byte usage plans. Some developers are experiencing a React Native app that is too large to install on their phone. This can be caused by various reasons, such as an app having too many modules or components. One solution to this problem is to use the Expo app. The Expo app is an app that is specifically designed for developers who are creating React Native Apps. Expo provides a mobile environment for the developer to test their app on the go. The Expo app is also significantly smaller than the React Native app, which means that the Expo app will not take up as much space on your phone. If you are a developer and are experiencing this problem, you should use the Expo app to test your React Native app.
