Im sure some of you know about this already and also possibly know of others that may work but if your like me and like free things them this is for you. Its called Racechrono and i got it free from the OVI store for my 5800 nokia. It does all sorts of timing as well as lap timing, because its GPS based i think it will auto reset the counter as you complete a full lap leaving you to concentrate on doing your hot laps. It works a treat on my phone as you know some applications are poor this is not.
