To use the app simply hold your phone flat, just like you would hold a real compass.

Important:

1. Your device has to have a Magnetic Sensor. Otherwise you won't be able to use the compass app.
2. If you have a magnetic case this will interfere with the device's readings. In order to use the compass please, remove it from the case.

When the compass is in use, the rose is aligned with the real directions in the frame of reference, so, for example, the "N" mark on the rose really points to the north.

In addition to the rose, angle markings in degrees are shown on the compass app.
