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 the sun marker (or a peak label you recognize) until it sits exactly on the real thing: sideways aligns heading, up and down tunes the camera field of view, remembered on this device.
