Consciously counting mistakes (i.e. everything you wouldn't do again that way) stimulates learning.
Moto Score is intended to be used with a headset with a button on it.
Simply press the button to log a mistake while riding.
Keep the button pressed for a full second to signal start or end of a ride.
MotoScore is open source:
