Expo

Expo is an open-source platform for developing mobile applications in the React Native environment. It allows you to create both Android and iOS apps using a single code, without the need for in-depth knowledge of native development.

The platform includes a number of tools, libraries and pre-made components that speed up and simplify the work of developers. Expo also offers the ability to test the app directly on the mobile device without the need for compilation, which speeds up the development process and saves time.

Expo is most often used in the development of simple to medium complex applications, prototypes or MVPs. It is also suitable for companies that want to quickly validate an idea or maintain smaller internal tools without high demands on technical infrastructure.

Some of the companies that use this platform include Pizza Hut or Codecademy.
