# BackpackMap

> BackpackMap is a free iPhone app for hikers and backpackers, in a free TestFlight beta. It warns you when you leave the trail, gives the exact distance along the trail to any point you touch, keeps topo maps offline, and gets the weather, active fires and flash-flood risk back from one iPhone Messages text, sent as a regular text or as a satellite text on an iPhone 14 or later. Texts go through Signal Fire, a separate service BackpackMap integrates with.
