Digital Wellbeing is an Android application that tracks application usage. This application is now installed by default. Most devices running Android 10 and higher have Digital Wellbeing. According to Barak Goldberg, the Pixel is one of the only devices to have this application on Android 9 - 12.¹  Everything from starting an app, stopping it, pushing it to background and bringing it into focus are tracked in the USERDATA/data/com.google.android.apps.wellbeing/databases/app_usage.  The user leverages this file to see where they are spending time and to configure how frequently and when they are “bothered” by their installed applications. Digital wellbeing also keeps track of web history on Chrome. Web history is not captured by default; user has to enable this feature.

Josh Hickman released research and his blog on Digital Wellbeing, which has been implemented into ALEAPP.

Physical Analyzer and AXIOM also parse this artifact.
