Adding App Usage As a Data Source
Data Collection Behavior
The App Usage data source collects data for all apps that run in the foreground on the participant's Android device. Data collection starts automatically when the participant grants the necessary permissions and continues as long as the app is running and has the required permissions.
Monitoring App Usage Data
There are two ways to monitor and export App Usage data: using the Data Export page and using Kibana.
