This is the bundle for everyone focussed on vehicle performance. It includes the well known Harry's Petrolhead app, the advanced tool for track day participants. It records all types of sensor data provided by your iPhone/iPod/iPad (or external sensors), combines them, and makes them available to optimize your drive. Over time, you will get insights on your car and in your driving, not known before. Furthermore it has included our new Harry's Dyno app, a high precision performance measuring app. It utilizes GPS and OBD sensor input to recognize arbitrary speed ranges like 0-60 mph or 100-200 km/h. Both acceleration and deceleration testing is supported. We use LapTimer on track and Dyno for drag racing and other performance tests.
