OnlyTrails

Your hike is saved on your phone before anything else — no signal, no account. Offline topo maps, an off-route alarm, and the same navigation on Apple Watch.

Your hike is saved on your phone before anything else. Not in an account, not after a sync: the recording, the route and the map are on the device in your hand from the moment you press start.

It works with no signal and no account. Download a trail’s topo tiles once and follow it with the radio off. Finish and save a hike with no session, no server and no bars.

Apple Watch runs the same navigation, not a remote control for it — the route, the off-route alarm and the eyes-free cues are on the watch, and stay there when the phone is in your pack.

OFFLINE TOPO MAPS • OpenTopoMap tiles with true contour lines and hillshade, plus USGS Topo and standard basemaps • Download the tile corridor along the whole route, not a rough box around it • Trail lines colored by steepness, with an elevation profile and grade chart

NAVIGATION THAT SURVIVES THE DAY • Off-route alarm plus a saved breadcrumb log for retrace and where-am-I, offline • Eyes-free mode: spoken and haptic fork cues on a near-black glance screen • Adaptive GPS drops to coarse between forks and counts steps with the motion coprocessor, waking full GPS at the decision points • A battery-versus-ETA budget that tightens power saving as your charge drops

BRING YOUR OWN ROUTE • Open any .gpx from Files, AirDrop or another app • Draw a route on the map, snap it to real paths, or fork someone else’s and edit it • Automatic distance, elevation gain and drop, grade and difficulty

ALWAYS FREE, NEVER GATED • Starting, finishing and saving a recording • Opening an offline map you have already downloaded • Exporting your own routes and recordings as GPX • Following a route, the off-route alarm, retrace and where-am-I • Watch navigation of a route on the phone • The app itself, without an account, offline, indefinitely

THE CATALOG, HONESTLY The community catalog is deepest in Chiang Mai and northern Thailand today — that is where the hikers and the verified routes are. Anywhere else, bring your own: import a GPX, draw a route, or just record as you walk. Recording, navigating and saving work the same everywhere on earth.

COMMUNITY • Share and discover routes, with crowd difficulty voting and reviews • Junction markings (Bee · Thorn · Slippery · Fork) and “What-the-Fork” photos pinned to confusing forks • Group hikes and events, with a poster you can paste straight into a chat
