All the features of ViewRanger will work on OpenPisteMap, so you can; record your track of distance covered and performance stats for après ski bragging rights, tag the location of restaurants or picnic spots, as PoI’s, so they are easy to find. And the BuddyBeacon location sharing feature will be really useful to reunite your group after someone has taken a wrong turn**.
