 # FirebaseUI for Android — UI Bindings for Firebase
 
-FirebaseUI is an open-source library for Android that allows you to quickly connect common UI elements to the [Firebase](https://www.firebase.com) database for data storage, allowing views to be updated in realtime as they change, and providing simple interfaces for common tasks like displaying lists or collections of items.

 A compatible FirebaseUI client is also available for [iOS](https://github.com/firebase/firebaseui-ios).
