Winter and avalanche safety on iPhone
Last updated 2 June 2026
Winter travel adds real hazards, avalanche terrain, hypothermia, and frostbite among them, and signal is often worst exactly where the risk is highest. Ferdinands Outdoor Companion (FOC) covers avalanche awareness and cold-weather injuries in its offline reference, free and on the device. It is a reference, not a replacement for avalanche training.
What winter safety covers
FOC's hazards and first-aid sections cover avalanche awareness, recognizing dangerous terrain and conditions, plus hypothermia and frostbite, how to spot and respond to them. Related sections cover shelter in snow and staying warm. Because it lives on the device, it is there in the backcountry where there is no signal.
Knowledge, not overconfidence
Avalanche terrain demands proper training, the right gear, and good judgement; an app supports those, it does not replace them. FOC is free, with no ads, no in-app purchases, and no tracking, and works fully offline. Take an avalanche course, carry a beacon, shovel, and probe in avalanche terrain, and travel with people who know the area.
