ReactiveX

You can’t get around functional programming when you develop an app. ReactiveX combines the observer pattern, iterator pattern, and functional programming all in one. It’s a core framework that makes it easy to combine front end and back end, and it’s available for most platforms. We use this framework in most of our Android projects.

Realm

Realm is a powerful framework for mobile databases. It can replace the cumbersome SQLite while being much simpler and faster. With well-written official documentation and simple setup, Realm promises to save weeks of development time. As an added bonus, search speeds with Realm are much faster than with other database frameworks. In terms of the user experience, this means a faster, more agile app.

Retrofit

Retrofit is a client-server framework for exchanging data between an app and a server. Retrofit is much easier to work with than alternatives such as Google’s Volley library.
