Hunter's comment
Not all android devices have a built-in magnetometer, so please be advised that it may not work with your device.
Icon and text will indicate if device is compatible once application starts.
Accuracy is dependent on manufacturer.
A magnetic field sensor (also known as magnetometer) reports the ambient magnetic field, as measured along the three sensor axes.
