Trailtether: Hike & Stay Safe

A tactical navigation and GPS application supporting multiple coordinate systems (WGS84, SK-42, UTM, MGRS), a compass with magnetic correction, and tools for measuring distance and area on topographic maps.

When traveling, hiking, or fishing, save your position such as a parked car or hotel location, and return back using the directional arrow.

The app provides offline maps and navigation based on OpenStreetMap data, but in recent versions users encounter frequent crashes, map loading issues, file import problems, and aggressive monetization.
