Understand the in-app experience for your connected mobile apps
The App developer collection summarizes data about the in-app user experience for versions of your app that include the Google Analytics for Firebase SDK. The collection is meant to help Android and iOS app developers monitor the performance of their app.
Access the report
The App developer collection is added on the left automatically when you add the Google Analytics for Firebase SDK to an app in your Google Analytics property.
Available reports
The App developer collection includes the Firebase overview report, which provides the same information as what the Firebase Dashboard provides.
