Ratings and reviews

Seems like a good lap for certain kinds of racing like slot cars. I've been trying to use it for short-course racing trucks on a dirt oval. Motion detection mode doesn't have a great range, you have to risk hitting the camera in order to get it to recognize a lap. Also, I couldn't get the Colortrax function to work. My truck is blue on the front half that fades to black at the rear half. When attempting to pick either color it keeps stating that the color is part of the background.

Fantastic App! I love the display and motion detection! Spoken lap times are tremendously valuable! Works flawlessly on S9+ I would like to see a YouTube video on how to use each function. A listing of laps and times at the end of a race would be nice. It only gives a partial list. I would love to see a Minimum Lap Time option to weed out false double lap captures like what can happen when your RC car crashes in front of the camera. Whomever it was that made this app, Great Work!!!

I needed a consistent and audible lap timer that was quick to reset on the fly and keep stats on performance. This is very snappy! Short (read as: brief) learning curve for basic feature customization (depending on how you want to set it up), but very well designed, customizable, and consistent. Voice feedback customization is a big plus in my book!
