Keep track of Mini4WD and slot cars lap times using your phone camera.

Easy to use:
★ Place the phone alongside the track, with the red line on the camera preview facing on a track lane.
★ Press calibrate: the app will calibrate in a couple seconds.
★ Press start and put your Mini4WD in the track.
★ The app will record your lap times as the Mini4WD passes under the red line.

You can export the lap list as CSV (for import in Excel) or send it directly via email.

Can also be used with slot cars or for other purposes.

Please use the app in a well lit environment. The app uses differences in shadow to detect the passing car. Other moving things that cast shadows on the track will interfere with time recording. Good lighting also improves camera framerate so times will be more precise.

    Great app. But can be improved to make the stopwatch accurate to milisecond, 0.001 sec accuracy. Now only 0.1sec.

    I discovered this when looking for a way to do "qualifying" for our old HO slot cars. It works great, and I want to get the code to add a couple more features! Android rocks my Droid4.

    Works great as a 1 lane lap timer on a 1/32 slot car track. Propped up my sg3 inside a roll of duct tape.. worked 98% of the time. Good enough to tune my cars with. Recommended!
