The new iPhone app, gForce, from Porsche and Mobil1 answers a very serious question about your driving: “What type of gravitational force are you pulling?” The free iPhone app is simple: press the start button and immediately begin recording your driving speed, distance, duration and g-force. Hit stop when you’ve completed your drive. The app does an excellent job of graphing out your g-force changes throughout the drive with the ability to share it with others.

Play it safe, though. As they state on the app page; “Porsche cannot be held responsible for any damage inflicted on persons or objects of any amount.” Safety first. (cm)
