# Firebase ABTesting SDK for iOS

A/B testing is a Firebase service that lets you run experiments across users of
your iOS and Android apps. It lets you learn how well one or more changes to
your app work with a smaller set of users before you roll out changes to all
users. You run experiments to find the most effective ways to use the
Notifications composer and Firebase Remote Config in your app.
