Record your hike
Tap record and put the phone in your pocket. OpenHikes keeps the track with the screen off and fuses the barometer into the elevation, so the climb is the climb. A recording survives the app being closed. Siri and Shortcuts can start, pause and stop it, and Control Center can start and stop it.
Plan a trail
Put stops on the map and each leg is routed along real paths, so the length is the length of the walk. Reorder the stops like directions in Apple Maps, then save the trail and hike it.
Maps that work with no signal
OpenStreetMap is the default, and free. Areas you browse are kept automatically, so the map you looked at last night is still there in the valley with no bars. Color the route by steepness or by difficulty.
Bring the GPX you already have
A .gpx file from Files, AirDrop, Mail or any share sheet opens straight into the app, with its statistics and an elevation profile you can scrub. Share a hike and you get a standard GPX file back, so nothing is locked in.
Places along the trail
Viewpoints, summits, water, shelters, camps and parking along your trail, from OpenStreetMap. Attach your photos to them, or mark places of your own.
Photos where you took them
Pictures from the hike are pinned to the point on the trail where they were taken, found by their timestamps or picked from your library. Share a hike as a picture: its line and figures over one of your own photos.
Trails other people have hiked
Pan the map and ask, or search by name, for hikes other people have published and the waymarked routes OpenStreetMap knows about. Publishing your own is free, and a person reviews every hike before anyone else sees it.
On your Lock Screen and Home Screen
A widget draws your trail with its progress. While you record or follow a trail, a Live Activity keeps the figures on the Lock Screen and in the Dynamic Island.
Weather, Health and iCloud
Apple Weather sits over the map. Finished hikes can be saved to Health as workouts, and your hikes follow you to your other devices through your own iCloud.
