Improve your lap times with the help of TrackPro: the intuitive and easy-to-use lap timer designed by drivers, for drivers.

TrackPro uses the iPhone's built-in GPS to accurately record lap times at over 80 North American tracks.  Simply mount your iPhone in your car's windshield, turn on TrackPro, and drive!  TrackPro will automatically detect which track you're running and start the lap timer when you've reached 20 mph.  Every time you cross the start/finish line, the elapsed time, top speed, and average speed for the lap are automatically recorded in a lapping session.  You never need to take your hands off the wheel, or even watch your iPhone while you're driving!  A full history of events, sessions, and laps are saved and easily exported so you can save your sessions to your desktop and compare your historical results.

 

Whether you're an amateur driver practicing for an upcoming event or an enthusiast out for a day of fun, you'll find TrackPro to be a valuable data acquisition system that doesn't break your budget and stays out of your way.
