Firebase (via BigQuery)
Firebase is Google's mobile app analytics platform. Firebase lets you share users, data, and analytics across platforms, meaning your users have the same experience whatever device they’re on and you can manage performance all in one place.
You can use Data Studio to turn your raw Firebase Analytics data into informative reports that are easy to read, easy to share, and fully customizable. It does this by leveraging its BigQuery connector: after you link your Firebase app to BigQuery, your BigQuery dataset can be visualized beautifully in Data Studio.
How to connect to Firebase via BigQuery
To help get you started, Data Studio provides two sample reports that are based on a comprehensive set of metrics and dimensions available through your BigQuery schema. Please refer to this article in the Firebase Help Center to learn more.
