Cairn – Hiking Safety Tracker is an outdoor route and trip-sharing app. Users can download offline maps, record a GPS route, and review distance, elevation, estimated arrival time, and predicted cell coverage. A trip can be shared with a safety circle so contacts can follow the route and receive an alert if the hiker is marked overdue.
The listing says maps, trails, and cell-coverage data are free, while Cairn Premium offers additional safety features through a subscription. A seven-day free trial is listed, but current prices and the exact features included should be checked in the App Store.
Trip sharing and alerts depend on device settings, location permissions, connectivity, and the recipient’s ability to receive messages. Cairn cannot guarantee rescue or replace a satellite messenger, emergency beacon, paper map, or trip plan filed with a trusted person. Coverage predictions are estimates, not live service guarantees. We have not tested alert delivery or map accuracy; carry appropriate backup tools and follow local safety guidance.
