7. Mammut Safety (iOS/Android)
Avalanches remain a threat for those speeding down a slope. Here is a multi-platform app that reduces the risk of being buried alive in snow by informing snow sport enthusiasts with up-to-date warnings in the area. It accomplishes this through the use of a clinometer that estimates the angle of a slope, plus a compass and altimeter to determine any dangers. In the event something transpires while out on the run, users can send SOS text messages to emergency services with co-ordinates to aid in any rescue missions.
