The app includes many great ideas but fails on the basics: Providing reliable information about the distance and the altimeters skiied. Several members of our skiing group used the app, often it did not track properly (e.g. one day it only tracked the vertical drop but not the distance skiied, another day it did not track at all even though tracking was activated, the data given was often clearly wrong). Nearly all members of the group had problems with the app crashing. For one member of the group the daily totals skiied do not add up to the total calculated by the app. And so on ... I also do not understand why the app does not use the information from the ski lift gates to calculate the precise vertical drop if one enters the number of the ski-pass, as done for instance by skiline.cc. All in all a potentially great app that is poorly programmed and needs more work!
