PeakNav
Mountains in 3D, offline
Free · Designed for iPad. Not verified for macOS.
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).

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
PeakNav now speaks your language: the app was in English on every iPhone and iPad whatever the setting. It now follows the device's language, and has its own Language option in the Settings app.
NEW
• Ski slopes and lifts. Downhill runs are painted blue, red or black, flowing down the slope and named along their way. Lifts show their cabins and chairs moving uphill. Areas downloaded with an earlier version need downloading again to get them.
• Route to here. Tap the map and a new button finds the walk from where you stand to that point along roads, tracks and paths. Walking time follows the slope, so the route prefers the quicker way round a hill.
• GPX info pane: distance, walking time, ascent and descent, highest and lowest point, a height profile, and a speed graph for recorded tracks.
• GPX tour: a marker shows where along the track you are, and a route or a track opened from the web can be shared from the share sheet.
• Search finds about 7,000 famous mountains worldwide, with their country, finds names from their first letters ("Matterh"), and goes to coordinates written in almost any form, including geo:, Google Maps and OpenStreetMap links. Online results come in your own language rather than the local script.
• A slideshow of the app on the welcome screen and while maps download, with the download's percentage.
• The tutorial now works on iPhone and iPad (it showed a blank page), with new pictures of the app as it is now.
• iPad: phone-sized buttons and text, which also keep their size in Split View.
• Longer battery life: at most 60 frames a second, and 20 while nothing on the map moves.
• The Labels switch hides or shows every label at once.
FIXES
• The gyroscope view works on devices without a compass, such as the iPod touch.
• No more black photo when camera access is denied: the app explains and offers to open Settings.
• Buttons and text are sized correctly on iPhones and iPads from 2020 onwards.
• The options menu is no longer covered by the location pin and photo buttons, and the photo bar's close button no longer covers "?".
• Going to a place with no downloaded data no longer leaves "Loading..." on screen: the app offers to download it.
• Changing units updates the labels already on screen and the search results.
