Which mountain is that? Point your watch at it and find out.

PeakHorizon turns your watch into a peak finder. It draws the ridge lines around you from real terrain data, marks the summits and names the peak under the crosshair, with its height, distance and direction. Optionally it adds lakes, sea, glaciers, towns, and the sun and moon, with when the sun really sets behind the ridge in front of you.

HOW IT WORKS
• Hold the watch up in front of you, like a camera: the mountains are right behind the screen
• Turn around: the compass turns the view with you
• Lift or lower your wrist to look higher or lower
• The peak nearest the crosshair is named at the bottom

WHAT IT SHOWS
• Ridge lines up to 50 km away, the skyline in bold
• Every named summit in view; peaks hidden behind nearer ridges are left out
• Name, height, distance, bearing and elevation angle of the selected peak, and the distance to the terrain under the crosshair
• Optional: lakes, sea and glaciers where you can actually see them, towns as little orange houses, and the sun and moon with their paths
• Earth curvature and refraction are taken into account

BUTTONS AND TOUCH
• UP / DOWN, or swipe down / up: move the view up or down
• Swipe left / right: fine-tune the compass, 2° at a time, if the ridges don't line up with the real ones (Reset compass in the settings undoes it). On touch watches, exit with BACK
• Tap the screen: lock the peak under the crosshair, so you can find it again (an arrow points the way). Tap again to unlock
• START (top right) or hold UP: settings. Lock a peak, choose which peaks to mark (all, major, or main summits), turn water, glaciers, sun & moon and towns on or off, and pick a light or dark screen. The same settings are in the Connect IQ app on your phone

WORKS WORLDWIDE
The relief is computed for your position on the PeakHorizon server and arrives through your phone in about a second, and again after you move 150 m. Your phone needs Garmin Connect and mobile data. The watch keeps the peaks and the last 30 reliefs, so reopening the app or walking back the way you came works offline.

SETUP
1. Open PeakHorizon with your phone nearby, connected to Garmin Connect.
2. Allow the permissions when asked.
3. Wait for the GPS fix; the relief appears a second later.

GOOD TO KNOW
• If the view doesn't line up, calibrate the compass in your watch's sensor settings.
• Watches without a compass can only turn the view from your GPS direction while you walk.
• Ridges are stretched 2× upwards to read clearly on a small screen.
• Terrain detail is about 185 m within 12 km, 900 m beyond. Peak names and heights come from OpenStreetMap; coverage varies by region.
• Uses GPS, compass and motion sensor while open: close the app when done to save battery.

PRIVACY
To compute the relief and find the peaks around you, the app sends your position to the PeakHorizon server through your phone. There are no accounts and no advertising. See the privacy policy.
