The ski performance app collects accelerometer and gyroscope data from your phones´ sensors to measure how much g-force power you put in to your skiing and how consistent your turns are."
To get the best data, you should put the phone in your pant pocket after pressing start. The system will then output your best 20 seconds of skiing.
The system calculates the accelerometer variance from the phones' 3 axes to find out how much power you put in to your skiing. This means that the more the acceleration oscillates, the higher the variance will be. Powerful turns with high frequency will therefore output a high variance. If you score 100% it means that you have skied with the same turn power as a professional Austrian skier with the highest ski instructor education.
