Launch the app and point it towards the peak to display the peak’s name in AR. Holding the phone upright activates AR mode, while pointing it downward switches to Terrain mode. In AR mode, aligning the guidelines with the peak on the screen allows you to confirm the peak’s name.


AR Mode

This mode is activated by holding the device upright. In the camera preview, AR overlays the peak’s name label and ridge guidelines. You can adjust the position of peaks or guidelines via swiping.


Terrain Mode

This mode is activated by pointing the device downward. 3D terrain created from data obtained by artificial satellites is displayed, providing a top-down view of the current location. You can adjust the angle and height with a swipe.


Edit Mode (Stable Mode)

Holding down the shutter button freezes the camera preview and switches to edit mode. Even if you load an image from the album, it still switches to edit mode. The gyroscope sensor stops, and the zoom in/out () button appears, which can be toggled on or off. This mode is useful not only for saving photos with the peak’s name but also for verifying the peak’s name or altitude.


Basic Operations


Tapping the peak’s name label (or the name at the bottom center of the screen) selects that peak. Tapping the selected peak again or the  icon displays details about that peak.



You can move the peak label and ridge guideline up, down, left, and right. If the AR display, such as the peak label, is misaligned with the actual mountain, use swipe gestures to move and align it.



You can zoom in or out on the image. Useful for checking distant peaks or adjusting the photo’s range.



You can rotate the peak’s name label or ridge guidelines. Useful if the loaded photo is tilted.
