Median unique session duration (d)

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

Median session duration per device is defined by the number that divides a sorted ascending list of median sessions durations of each device in half (excluding broken sessions).

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.

MyTracker records information on the occurred session after the user ends or interrupts it and launches a new session.
