This is a digital compass that can tell you the direction at any time.
Keep the device away from metal objects to avoid false results. When the device is close to a metal object, the compass will point to the wrong direction. Then you need to calibrate the device by moving it in figure 8 pattern. You can re-calibrate it at any time to make sure the direction of the compass is right.
Your device must have magnetic sensor to use this application. If your device does not have magnetic sensor there is no compass app can work on it.
The button at the bottom of the screen can close/show the digital clock.
