Love the 3d maps and trail descriptions. This app functions as a great trail map, and very happy to see Crystal my home mountain. I wouldnt use this to track your runs though. Seems like a big lost opportunity. Maybe I just dont get the UI, but what I really wanted to see is where I skied today, the app doesnt seem to offer the feature of overlaying your tracks on the map??? Also couldnt find the battery saver feature - app ran until it drained my battery, most ski trackers auto shut off at 20% battery.
