Teraguide

Point your phone at the landscape and see what you are looking at.

Live labels for peaks and places, with terrain-aware visibility: if a ridge hides a summit, its label hides too. Works from a beach, a boat, or an airplane window.

Private by design

No accounts, no analytics, no data collection. Camera, motion, and location are processed on your phone and never leave it. The network is used only to download terrain and place data.

Getting started

Allow camera, motion, and location when asked. To calibrate, drag anywhere; the world follows your finger. Put the ring around the sun or moon (or a peak label on its peak): sideways aligns heading, up and down tunes the camera field of view, remembered on this device.

Keep rotation lock on. For a clean full screen, tap ⛶ or add this page to your Home Screen. Tap ☀︎ to let the app align heading to the sun automatically whenever it is in frame.
