Compass - Magnetic North

Compass reads your device's magnetic sensor and shows which way you are facing, measured from magnetic north. The main screen shows your heading in large degrees with the nearest of eight directions, from North through Northwest, above a dial that turns as you turn. Open Details to see the heading, the direction, the strength of the magnetic field in microtesla and the sensor status. When nearby metal, magnets or electronics push the field outside the normal range, the app warns you about interference. A hint reminds you to move the phone in a figure-8 to recalibrate the sensor. The app does not use your location or ask for an account. It never asks for location permission, because the heading comes from the magnetic sensor alone. The compass itself works without an internet connection. Magnetic north differs from true north by a few degrees depending on where you are. Available in English, Korean, Japanese, Chinese (Simplified and Traditional), Spanish, French, German and Portuguese.
