Compass Pro

Compass Pro shows True North, latitude/longitude, altitude, speed, sensor state, level, magnetic field power, device slope angle, and level error correction. It functions as a realistic 3D compass that works without internet connection.

Yes, Compass Pro works offline and doesn't require internet connection or GPS signal to function as a basic compass. It uses the device's built-in magnetometer sensor.

The compass accuracy depends on the device's magnetometer sensor. Magnetic interference from nearby metal objects, phone cases with magnets, and environmental factors can affect readings. Moving away from interfering objects should restore accuracy.

First try rebooting your device. If that doesn't work, delete and reinstall the app. Also verify your device has a magnetometer sensor, as the app won't function properly without one.

The app supports multiple formats including decimal degrees, degrees-minutes-seconds, magnetic and true north readings, altitude in feet/meters, and various position formats like UTM and MGRS.
