Firebase Analytics is user and event-centric and gives you insight into what your users are doing in your app. You can also see how your paid advertising campaigns are performing with cross-network attribution, which tells you where your users are coming from. You can see all of this from a single dashboard.
Firebase Analytics is also integrated with other Firebase offerings to provide a single source of truth for in-app activity and through a feature called Audiences. Audiences let you define groups of users with common attributes. Once defined, these groups can be accessed from other Firebase features -- to illustrate, we’ll reference Audiences throughout this post.
