PeakNav

See the mountains around you in 3D — now with the paths across them: trails graded by difficulty, named and numbered along the way. Still fully offline.

PeakNav shows you the world's mountains in 3D — as if you were standing there.

Pick any place on Earth and PeakNav rebuilds the landscape around it from real elevation data: ridges, valleys, glaciers and summits, each peak labeled with its name and height. Turn the view with a finger, or just point your iPhone at the horizon and let the motion sensors aim the view where you are looking.

WORKS OFFLINE Download an area once and everything works with no connection at all — perfect for the summit, the trail, or the airplane window. Elevation, peak names and map data are stored on your device.

NAME THAT PEAK Wondering what you are looking at? Center your position with one tap on the location button and compare the labeled 3D horizon with the real one. Around a quarter of a million summits, towns and villages are searchable by name on the device, in their local spellings too — Großglockner, Grossglockner and Monte Bianco all work.

YOUR HIKES IN 3D Open a GPX track from Files, Mail or any app's share sheet and see the whole route draped over the terrain — every switchback, every col, the way it actually climbs. Then fly the route as a tour, seek bar included. Great for planning tomorrow's hike or reliving today's.

A REAL SKY, AND A WAY AROUND EVERY PEAK Sun, moon — with its phase — and stars stand where they really do for the date, time and place you are looking from, with the compass points marked on the horizon and an optional sky map with an astronomical grid. Tap a summit and choose orbit to circle it and see it from every side.

PHOTOS KNOW WHERE THEY WERE TAKEN Choose a photo and PeakNav flies you to the exact spot it was shot from, so you can finally put a name on that summit in the background.

SATELLITE AND MAP IMAGERY Drape the terrain in satellite imagery — USGS Imagery Topo or NASA Landsat — choose the source you prefer, or add your own tile provider (any https tile URL).
