Porsche enthusiast site flatsixes.com has an exclusive first look at the app, which is still in development but is reported to be coming “soon.” Based on preliminary screenshots provided by Porsche, the app instructs users to set up a variety of courses -- cone slalom, autocross and reaction-time challenge courses are shown -- then uses the iPhone's internal accelerometer and GPS receiver to track and record your performance. You'll also be able to use the app's “record your curve” function to share favorite drives with friends on Facebook.
