CompassPro turns your phone's magnetic sensor into a compass.
- Live heading in degrees, with the direction written out (north, north-east, east and so on).
- A clear dial with ticks every 5 degrees and labels every 45 degrees (N, NE, E, SE, S, SW, W, NW).
- An accuracy indicator (high, medium or low) that tells you when to recalibrate, with a simple figure-eight prompt.
- Optional true north: allow one approximate location check and bearings show true north as well as magnetic; say no and bearings stay magnetic.
- Bearing detail: declination, magnetic field strength, an interference check and the back bearing.
- Sight: aim through the camera to line up a bearing, then save it with a photo.
- Log: every saved bearing, with its photo, time and direction. Share, copy or delete any entry, with undo.
- Degrees or mils, a photo stamp you can turn on, and a light, dark or system theme.
Good to know
- The compass points to magnetic north by default. True north uses one approximate location check to work out the local difference (declination); your position is never stored, logged or shared.
- Metal objects, magnets, magnetic phone cases and electronics nearby can disturb the reading. If the heading looks wrong, move away from them and move your phone in a figure-eight to recalibrate the sensor.
- Hold the phone flat for the steadiest reading.
- Your phone needs a magnetic sensor (magnetometer). The compass works without an internet connection, and your saved bearings and photos stay on your device.
- CompassPro is a general-purpose compass. Do not rely on it as your only means of navigation.
