@Wenzudeg This is a more complex issue than it seems. In my opinion, it’s currently too easy to accidentally end an activity (e.g., by putting on a jacket, gloves, etc.), and the obvious solution for me is to use the map screen, which doesn’t offer an option to end the activity.
Suunto could reconcile these two different philosophies, allowing for quick and convenient activity termination without the risk of accidentally ending it too soon, which currently happens.
