    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!
