"Data recorders can be invaluable tools for driver improvement on the racetrack. If you own a late-model BMW equipped with the BMW apps option, you can now get access to all your car&amp;#039;s crucial data via the free M Laptimer app.  Developed in California by BMW, the M Laptimer records GPS data, throttle position, brake pressure, steering angle and a number of other functions directly from the car&amp;#039;s computer and organizes it in an easy to interpret graphic format.  You&amp;#039;ll be able to scroll through your laps, analyze your performance and compare it with data from a friend, instructor, or social media contacts. So, if you&amp;#039;ve got a newer Bimmer and an iPhone, there&amp;#039;s no excuse not to start crunching your own numbers. The app is available for free on the iTunes App Store      "^^<http://www.w3.org/2001/XMLSchema#string>
