React Native is a popular framework for building cross-platform mobile applications that work on both the iOS and Android platforms. It is an open-source framework that is based on the React library used for building web applications.

React Native uses the same fundamental UI building blocks as regular iOS and Android apps, but with the added advantage of using a single codebase for both platforms. This allows developers to write code once and use it on both platforms, making development faster and more efficient.

Some of the key benefits of using React Native for app development are:

Cross-Platform Compatibility: React Native allows you to build apps that work on both iOS and Android platforms with a single codebase. This makes development faster and more efficient, as there is no need to write separate code for each platform.

Hot Reloading: React Native supports hot reloading, which means that changes made to the code are instantly reflected in the app. This makes development faster and more efficient, as developers can see the results of their changes in real-time.

Improved User Experience: React Native provides a smooth and responsive user interface, making the app feel like a native app. This improves the overall user experience and can lead to higher user engagement and retention.

Cost-Effective: As React Native allows you to use code on both platforms, it can be a more cost-effective option.
