Average unique session duration (d)

The average session duration in seconds per device during the specified period.

Avg. session dur. per device = sum of average sessions durations of each device /  number of devices.

The session is a time interval during which a user continues to interact with the app.

For mobile apps, the session starts with the launch and stops when the application goes to the background for more than 30 seconds. You can change this interval by configuring the LaunchTimeout parameter of MyTracker SDK (see documentation for iOS, Android, Unity, Flutter).

For web apps, the session starts with a page view and stops when more than 30 minutes have passed since the last view.
