Why hikers and riders keep it

Made for the places where the signal ends.

Works where the signal doesn't

Download your country once: topo map, trails, huts, contour lines and elevations stay on your phone.

Plan in a minute

Tap the map and the route follows real trails, with distance, gain, estimated time and arrival time. Or ask for a loop from where you start.

Know the grade

Trails colored by the SAC T1–T6 hiking scale and the Singletrail S0–S6 MTB scale, with filters for what you don't want to see.

Honest numbers

Elevation gain from the barometer, filtered for noise, not inflated. Every track keeps its profile and stats in your log.

Apple Watch on the trail

Start from your wrist, keep an eye on heart rate and effort zone, and find the workout in Health afterwards.

The weather ahead

Precipitation radar, lightning and hour-by-hour forecasts for any spot on the map, from public weather services.

Peak Explorer is not a safety device. In the mountains, always carry a paper map, a compass and good judgment.
