The Screen time dashboard
How long people stay on each screen (the typical and the long visits), which screens hold them longest and which they open most. A visit is recorded when its screen is popped or replaced, so a screen covered by a push and never popped, such as a home screen, is missing.
Who it is for: Product and design: where people spend their time, and which screens hold them longest.
Open it from Dashboards in the Observatory: choose Screen time. It is a built-in board, so it is read-only; Save a copy makes one you can change. How every panel reads the range, its colors and its empty states is on Reading a board.
The toolbar: the filters Build, Platform and Screen, each All until you pick a value, and the time range. Each menu lists the values dartastic.screen.time_spent carries in the range. Each panel below names the filters that narrow it.

Long visits (p95)
One visit in twenty that ended in this range was longer.
- How it is computed: The 95th percentile of
dartastic.screen.time_spent. One figure for the whole picked range. - Compared: Beside the figure, its change from the prior range of the same length.
- Filters: Build, Platform and Screen narrow it.
- Opens: its title opens the Metric screen on
dartastic.screen.time_spent.
Screen visits
Visits that ended in this range. A visit is recorded when its screen is popped or replaced, so a screen covered by a push and never popped is missing.
- How it is computed: The number of
dartastic.screen.time_spentsamples. One figure for the whole picked range. - Better: Higher is better. Beside the figure, its change from the prior range of the same length: green when it moved the better way, red when it moved the other way.
- Filters: Build, Platform and Screen narrow it.
- Opens: its title opens the Metric screen on
dartastic.screen.time_spent.
