Trail alerts
Cairn automatically alerts your safety circle if you’re overdue and communicates important details, like where you’re headed and when you intend to return.
See where others have found cell coverage on the trail. Know where you’ll be able to check in with your contacts or make an emergency call. Cairn is the only place you'll find this specific sort of crowdsourced information for the outdoors.
