Activity (Sessions) List

This screen allows observing and analyzing your movement/activity sessions throughout the day without having to turn on explicit Activity Tracking on the watch.

Activity List dashboard

Make sure to adjust your personal settings and goals, available in menu: Settings → About you (or now also available via Settings → About you in the Charts screens → Settings icon.

  • Step length → this will be used to calculate distance from the number of Active steps.

The following items will be used to calculate percentage charts between your achievement and your goal:

  • Daily target: distance
  • Daily target: active time
  • Daily step target

Activity sessions

You can change how activities are being detected, via Charts → Settings → Activity list. Here are the determinig factors:

  • Activity session is detected by steps per minute or by activity intensity. Minumum steps per minute (this is internally linked to minimum intensity) required for an activity to be detected as activity session can be set in the settings Minimal steps per minute to detect activity
  • Activity session must be at least X minutes long, this minimal duration can be set in the settings Minimal activity length
  • Activity session ends with a pause longer then a given interval, it can be set in the settings Pause length to split activities
  • Activity session is marked as Running if steps/m > 120, this can be set in the settings Minimal steps per minute to detect run
  • Activity session is marked as Excercise if it has less the 200 steps but has heartRateAverage > 90 && intensity > 15

Icons meaning:

  • icon steps total Total Steps - this is the number of your total steps today. It is shown to be able to see a difference between active and total steps.

Intensity of activity

One of the new items in Activity List but also in the Sleep charts is intensity icon intensity. It is an interesting value which typically does not surface as a number, but in fact it has been used throughout Gadgetbridge charts a lot: the green spikes on axis Y in activity charts? Intensity. The light and dark blue spikes on axis Y in your sleep charts? Also intensity. It is a value (normalized to decimal between 0 and 1) that is representing a strength or an intensity of your activity, as determined by the bracelet. At night, the more you move, the higher this intensity is. During an activity or walk, the more your arm moves, the number seems to go up. So it seems good to expose this number even more, to be able to observe it, typically labeling it as Movement intensity. The displayed result is not calculated as an average but rather as a total sum of the intensity of a particular activity in activity list or in your sleep. Hopefully you'll find it useful.

Further possible improvements:

  • detect activities by ActivityKind (if stored in db)
  • better detection of activity sessions - right now, there is one generic threshold. Maybe we could try to detect more "levels of activity" and split activities by these levels.
  • add nicer names to some activity sessions (e.g. Morning walk)
  • burned calories
