RaceChrono is a GPS based lap timing software for Nokia Series 60
smart phones. It can be used to measure lap times on almost any
vehicle and track. It can be used to measure laptimes for example
for motorbikes, bicycles, cars, water jets and quadbikes.
The main feature is of course the Live Timer, which shows your
lap- and sector-times in real-time. Also included are a scalable
graphical display of traveled path, satellite reception display,
speedometer and a compass. When you're back at the pits,
you can also browse through your lap and sector times, or view your
trap speeds. Or maybe analyze your laps by graphs of time,
speed and altitude compared to any another lap.
All lap timing sessions are logged, and the results can be viewed
afterwards. The raw NMEA-output from the GPS is also saved,
so you can use that in other compatible software if you wish.
And yes, there's always the question of accuracy when it comes
to timing anything. After extensive testing, we feel really confident
on RaceChrono's accuracy. Our tests together with commercial lap
timers have showed an accuracy of between +- 0.03-0.10 seconds with
a cheap 5 Hz receiver. Switching to an ordinary 1 Hz SirfStar3
receiver RaceChrono was still very accurate - on the level
of +- 0.10-0.15 seconds. Keep in mind however that accuracy is
fully dependent on the quality of your GPS receiver and signal reception.
