I create an app for iPhone,/iPad called RC Race Timer. As the name suggests this app acts as a timer which you can use to time from either RC car races to karting heats and compare the final results.

It records laps and calculates final race stats. It's under your control to time up to 4 racers at a time by timing each of the races. It is possible to personalize the car/driver and track image and name in race prefs. After the heat you can manage races, compare results and see who's the fastest lap.

It provides a compare mode with two options(up to 4 racers). In the first it is possible to graphically determine the race winner. The 'lap position' compare chart offer the evolution for lap position along the race. Touch a point on the chart to see the lap time. Pinch to zoom to get more detail.

It is available on the app store by searching RC Race Timer, the author is feuggin.
As it is a new app I have 20 App Store promo codes to give away so you can keep it as yours for free. Please contact by email and I will issue the promo code for you while they last.

I also continue to support the android version which now has more than 1500 downloads on Google Play.
