Sometime you just don't have a level surface to calibrate on, but by simply rotating the device 180° on it's back, you can take a pair of measurements, the average of which is perfectly level.
Done on the device edge you can calibrate a single axis, and on it's back you can do roll & pitch.
Since this app doesn't measure yaw that doesn't need calibration.
