Expo

About

Expo is an open-source framework and platform for universal native app development. It allows developers to build, deploy, and iterate on iOS, Android, and web applications from a single JavaScript codebase, primarily using React Native.

It provides a set of tools and services that streamline the development workflow, including pre-built components, APIs for device features, and cloud services for building and deploying apps. Expo is designed for developers who want to create cross-platform mobile and web applications efficiently without needing to write platform-specific code.
