Aim the camera and a live overlay shows azimuth, pitch angle, level and GPS position right on the scene, so you read the field without juggling separate instruments. ▶ Measure the horizontal and vertical angle between two points by sighting each one. Estimate distance and height with trigonometry from your eye height and the target angles. ▶ Read your position in the format you work in: latitude and longitude in decimal or DMS, plus UTM and MGRS grids used worldwide. Switch true north and magnetic north as needed. ▶ Capture a photo with the heading, angle and coordinates stamped on it, a clean record for the site. Save station notes and reuse them later. ▶ Everything runs on device with no region data, so it behaves the same anywhere. Calibrate the compass for a steadier reading before you start. Results are field estimates based on your phone's sensors and are not a substitute for professional survey equipment. Confirm critical measurements with proper instruments. ## Key features - Live camera overlay for azimuth, pitch, and GPS - Measure horizontal and vertical angles - Estimate distance and height with trigonometry - Multiple coordinate formats (Lat/Lon, UTM, MGRS) - Capture photos with data stamps - Save and reuse station notes ## Frequently asked questions about AR Theodolite ### Does AR Theodolite have ads?
