Features
What the app does on a hike, and what it deliberately does not claim to do.
Recording that survives the trail
Start a hike and put the phone away. Recording continues in the background, keeps going where there is no signal, and picks up again if the app is interrupted. Nothing needs a connection while you walk.
Controls on your wrist
Start, pause, resume and finish from the watch, with live route and effort metrics on the watch face. Heart rate is measured on the wrist; distance, elevation and pace come from the phone, so the two devices never disagree about the same number.
Elevation and effort together
Distance, elevation gain and loss, moving time and pace, alongside heart rate through the hike. Calorie figures are estimates derived from your activity and health data, not measurements.
Weather and air quality context
A snapshot of conditions at the start of a hike and again at the end, plus an air-quality reading, so a hard day has an explanation attached to it afterwards.
A history you own
Every hike is kept on the device with its route, charts and summary. Rename, review, export as GPX, or delete — all without an account.
It notices when you are driving
If the recording starts to look like vehicle travel, the hike pauses and asks. This is a heuristic and it can be wrong in both directions, which is why it asks rather than deciding for you — and why it can never finish a hike on its own.
What it is not
Not a medical device, and nothing it reports is a diagnosis. Not a navigation or route-finding tool. Not something to depend on in an emergency — carry whatever you would carry anyway.
