ACCURACY, HONESTLY
A phone compass reads the magnetic field around it. Metal, magnets, speakers and magnetic cases can pull the needle off, and a case can block the sensor. Compass One warns you when the field looks disturbed and tells you when to recalibrate, but no phone compass is an instrument. Do not rely on it for critical navigation.

PRIVACY
No account. No analytics. No server. Your location is read only when you ask for it, and nothing leaves your device.

Requires a device with a magnetic field sensor.
