About Mini4WD Lap Timer
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.
❌ Do not cast shadows on the track or measuring will be wrong.
Can also be used with slot cars or for other purposes.
You can export the lap list as CSV (for import in Excel) or send it directly via email.

The app installed fine but it did not work very good. It worked once but after that every time I calibrated for a car it would ask to be recalibrated. Perhaps it doesn't like H.O scale cars or maybe it doesn't work well on my phone.

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!

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.

5 stars for update..Still a few more ideas like sound for every lap and a sound for best lap..and setup to delay sensor readings to avoid false laps;)

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