I like the new backcountry ski activity app. Coming from Suunto, who have a history of having an outdoor/mountaineering focus, this makes the transition to Garmin easier for me.
However, there is an annoying bug. In backcountry ski mode, the watch stops incrementing the step count (it still counts floors). This makes no sense for me as uphill in backcountry skiing is essentially a walking activity (with lots of steps due to reduced stride length).
