Compass Calibrator description

Get the correct calibration of the phone's internal compass using this simple application.
Using sun position at each instant, North orientation is automatically calculated, taking into account parameters such as latitude, longitude and time.
Usage is extremely simple. You only have to place your phone in the direction of the sun so that the plate of the compass is showing north position.
It also has an additional indication of the phone's orientation sensor to calibrate the same until it matches the calculated address. Orientation sensor is aligned with Earth's magnetic field, but the app corrects this magnetic declination, so that the compass needle should point to the real north, once calibrated.
