Peak identification · iPhone
Point your camera at a mountain. Trig identifies it, and every peak around it, in real time.
01 · Scan
Trig checks every nearby summit against an elevation model before it labels it, so you see the peaks the terrain says are in view, not every name on a map. The mountains in front of you get their names; the ones hidden behind a ridge do not.
Terrain-model visibility, not photo recognition.
Visibility check
Every candidate is traced across the elevation model from where you stand. Only a clear line of sight earns a name.
02 · Summit view Pro
Open an interactive 3D panorama from where you stand or from any summit. Switch elevation and relief palettes, follow the sun and the moon across the sky, and change lenses.
03 · Offline regions Pro
Save a region with a 5 to 150 km radius, including maps, terrain and peaks, then scan and explore with no connection, for the whole hike. Trig tells you when a region is fully ready.
How Trig identifies peaks: every view, line mode and style →
How it works
Allow location and camera. Trig loads the peaks around you from its built-in catalogue.
Aim at a clear ridge and pause. Trig matches the skyline to the terrain. If a label still sits off its peak, align it by hand; your alignment stays locked until you change it.
Tap any label for its name, height, distance and bearing, then open it on the map or share it.
Made in Bosnia and Herzegovina · Works worldwide
Trig was born here, on the mountains of Bosnia and Herzegovina, and its catalogue knows them by name. The same catalogue goes wherever you go: more than 1.4 million named peaks worldwide, and the AR sight check works on mountains from 56° south to 60° north. A few of them, from home to the roof of the world, exactly as the app stores them:
