Track every adventure.
Hike, bike, walk, run, ski or paddle with live stats on a 3D map — and keep recording when there's no signal at all.
21 activities
On foot, on wheels, on snow, on water — each activity type gets tuned tracking, from pace and splits for runs to vertical and ski runs in winter.
Works with zero signal
GPS doesn't need cell service. Your track keeps recording in airplane mode, deep in a canyon, or three days into the backcountry — and syncs when you're back.
Alerts that wait for real evidence
Follow a trail and Peaksur tells you when you have left it — only after you are clearly off the line for a sustained stretch, never for a single wobbly GPS fix under the trees. One alert per wrong turn, then quiet until you are back on route.
Elevation you can trust
Climb comes from your phone's barometer, the same sensor the best fitness apps rely on, so a flat mile stays flat and a real ascent counts in full.
On your Lock Screen, in Apple Health
Live Activities put your stats on the Lock Screen and Dynamic Island while you move. Workouts, heart rate and calories sync to Apple Health automatically.
Questions
Does GPS tracking work without cell service?
Yes. GPS is independent of cell signal, so recording continues with no service. Download an offline region first and you'll have the full map out there too.
How is battery life?
Tracking is built to be battery-sane and to last a full day out. Live Activities show your stats without keeping the screen on.
Does it sync with Apple Health?
Yes — workouts, heart rate and calories are written to Apple Health automatically, and your recorded activities stay private by default.
