Alpingo is an iPhone field GPS for hikers, climbers, geologists and prospectors. Save an area once — map, terrain, peaks and trails — and navigate, draw, route and log samples with no signal at all. No account needed; a one-time purchase on the App Store with no subscriptions, ads or in-app purchases.
Features
Offline use
GPS needs no cell signal or internet. Position, compass, waypoints, routes, track recording, alarms and tools all work in airplane mode. For maps, terrain, peaks and trail routing, download the area beforehand.
| Offline mode | What you get | How to prepare |
|---|---|---|
| Vector map pack | Roads, place names, water, forest and land cover; sharp at every zoom | The download button at the top left of the map screen, or Tools → Terrain Data |
| Terrain data | Slope/avalanche shading, hillshade, contours, 3D terrain, Peak Finder, ground elevation where you stand | Tools → Terrain Data → download the area |
| Peaks, huts & water | OpenStreetMap points on the map, in search and in Peak Finder | Downloaded together with terrain data |
| Path network | Walking and mountain-path routes that follow the trail with no signal | Downloaded together with the area |
| Weather forecast | The last mountain forecast you downloaded | Open it once while online |
| MBTiles | Your own raster maps (topographic sheets, orthophotos…) | Settings → Map → Offline maps (MBTiles) → Import |
| Viewed tiles | Topo and imagery areas you have already looked at | Kept on the device automatically |
| Magnetic model | Magnetic declination (WMM2025, valid 2025–2030) | Built into the app, nothing to download |
Apple does not make offline Apple Maps downloads available to third-party apps, so Alpingo uses its own vector packs and MBTiles files for offline maps.
