Speedr shows how much time, or how little time, you save by speeding in your car. Discover if speeding is really worth the risk by measuring how much of a time difference it makes.
Speedr has a speedometer showing you your current driving speed and the speed limit of the road. Anytime you drive faster than the speed limit Speedr calculates how much time the extra speed is saving.
