Compass - GPS Digital

Gps Compass For Android is a free and a very easy to use magnetic compass app. It shows information about the direction to the magnetic North Pole and the geographic coordinates. It also provides other useful information such as the strength of the magnetic field (in μT), GPS error and the accuracy of the gravity and magnetic sensors.
The compass graphics can be shown in a pseudo 3D mode.
An important feature is that it can work without network coverage, which is the situation that often occurs in places where a compass and a GPS are required (the countryside, the mountains, the sea, etc).
The accuracy depends on your device. Normally it is better when device is used horizontally. If the accuracy of the magnetic sensor is not good enought, you can improve it by moving your phone a few times, drawing a figure of 8 in the air.
