## What is Survey Compass?

Survey compass app for field angles: aim your phone camera at a target and read its bearing, elevation angle and GPS position on one live screen. It is built for quick outdoor checks such as sighting a ridge, a mast or a tree, logging where you stood, and working out a height from two angles.

▶ LIVE CAMERA HUD
• Azimuth ribbon across the top with the bearing in degrees and a 16-point direction (N, NNE, NE…)
• Crosshair reticle with a small bubble that shows when the phone is level
• Pitch gauge on the side with the elevation angle, percent grade and 1:n slope
• Switch between magnetic north and true north (true north appears once your location gives the local declination)

▶ YOUR POSITION IN THREE FORMATS
• Latitude and longitude in degrees, minutes and seconds
• UTM zone, easting and northing
• MGRS grid reference
While there is no GPS fix the panel shows a dash instead of a number, so a coordinate on screen always comes from a real GPS fix, never from a placeholder.

▶ A–B ANGLE AND HEIGHT
Mark point A, mark point B, and read the horizontal angle and vertical angle between the two sightings. Enter the horizontal distance to the object and the app estimates its height from the base and top angles. If you have a slope distance instead, switch to slope mode to get the horizontal distance and the rise.

▶ READING LOG
Save a reading with its bearing, pitch, coordinates and an optional note. Up to 200 readings stay on your phone. A reading saved without a GPS fix is marked as having no position rather than being given a made-up one.

▶ COORDINATE CONVERTER
Type any latitude and longitude, or pull in your current GPS fix, and read it as decimal degrees, DMS, UTM and MGRS at once. Add a second point to get the great-circle bearing and distance between them.

▶ SHARE
Send an A–B result as plain text to a message, a note or a work order.

HONEST LIMITS
Bearing and angle come from your phone's compass and motion sensors, and position comes from GPS. Nearby metal, cars and power lines disturb a compass; move away from them and hold the phone steady for a better reading. The app does not measure distance by itself: for a height estimate you enter the distance. This is a field aid for planning and estimating, not survey-grade instrumentation, so confirm critical measurements with proper equipment.

## 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

### 5/5 — Easy to use

*2026-10-07*

Thank you for the app. Is it possible to add a time stamp or may be I am missing something?

**Developer response:** Thank you for the kind words! Every reading you capture is already saved on the Log tab with its date and time, along with the bearing, angle and GPS position. The time stamp isn't part of the shared text yet; if that's what you need, let us know and we'll consider adding it.

## Frequently asked questions about Survey Compass

### Does AR Theodolite have ads?

Yes, AR Theodolite contains advertisements. As a free utility app, it utilizes ads to support its development and continued availability.

### What devices does AR Theodolite support?

AR Theodolite is currently supported on iPhone devices. Future updates may expand compatibility to other platforms.

### What is the age rating for AR Theodolite?

AR Theodolite has an age rating of 17+. This rating is typically assigned due to the nature of the utility and potential for complex data display.

### How often is AR Theodolite updated?

The latest version, 1.2.1, was released on August 3, 2026. This indicates a recent update, suggesting the developer is actively maintaining the application.

### Can AR Theodolite replace professional survey equipment?

No, AR Theodolite provides field estimates based on phone sensors and is not a substitute for professional survey equipment. Critical measurements should be confirmed with proper instruments.

### What coordinate formats does AR Theodolite offer?

AR Theodolite supports latitude and longitude in decimal or DMS, as well as UTM and MGRS grids, which are used worldwide for precise location referencing.

### How accurate are the measurements in AR Theodolite?

Measurements are estimates based on your phone's sensors. For optimal accuracy, it is recommended to calibrate the compass before use.

### Can I save my survey data with AR Theodolite?

Yes, you can capture photos with heading, angle, and coordinates stamped on them for a clean record. You can also save station notes and reuse them later.

## Version history (last 5 releases)

### 1.2.9 — 2026-10-07

• New name: Survey Compass. The app is the same camera HUD you already use: bearing, elevation angle, A–B height, the reading log and the coordinate converter all work as before.
• Your saved readings and settings stay on the phone exactly as they were; nothing needs to be set up again.

### 1.2.8 — 2026-10-04

• The bearing now follows where the camera points. Aiming up at a summit, mast or roofline no longer flips the reading to the opposite direction.
• Pitch shows a minus sign when you aim below level, so the A–B height, vertical angle and grade come out right for targets below eye level.
• With the phone pointing almost straight up or down, the bearing shows "—" and Capture reading waits, instead of a number that means nothing.

### 1.2.7 — 2026-09-25

• Capture button now sits right under the camera view, and "Saved · N in log" appears only after the reading is really stored
• No GPS fix: coordinates show a dash and the reading is marked as having no position (older versions used a sample location)
• Capture and A–B marking wait until both compass and tilt sensors respond
• Readings saved by older versions at the sample location are labelled unverified
• A–B result now shows a side-view sketch of your two sightings, and the converter draws the A–B bearing on a compass dial
• New icon and line icons

### 1.2.6 — 2026-09-05

Slope-distance reduction on the HUD A-B card.
Verify: HUD tab, mark A on the base and B on the top. Enter 50 in the distance field, tap SD. With A pitch about -10 deg and B about +20 deg, Horizontal distance reads ~49.2 m and Estimated height ~26.6 m. Switch to HD: height becomes ~27.0 m (the old behavior). Reset clears the number but keeps HD/SD.

### 1.2.3 — 2026-08-06

Alerts now arrive properly on Android instead of landing silently, and the app no longer interrupts you in the middle of what you came to do.
