Connect Looker Studio to Firebase Analytics.
Firebase is Google's web and 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 Looker 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 Looker Studio.
To create BigQuery data sources in Looker Studio, please refer to the BigQuery connector article.
