Comments on LapTrax - Advanced Lap Timer for Android

★★★★★ 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!!!

★★★★★ Using this app for HO slot cars on my Android phone this app works great. Made a bracket to suspend the phone over the racetrack out of foam core board and this is all I need to keep track of laps and Times of laps you have to play with it a little to learn what all the little buttons and gizmos do. Perfect for the home track and way cheaper than any other lap counter and timer I have seen

★★☆☆☆ Motion detect works ok but only with 1 car on track, color detect doesn't work well with red cars and not at all with red/white cars. The app also freezes occasionally (countdown doesn't start) and the final lap 'buzzer' still sounds even when deactivated. Saved files can't be deleted "in app" as far as I can tell. Overall the app suffers from limited functionality at least with my phone (Huawei P Smart 64gb) Hate to be critical as the app has potential and is free but only 2 stars from me.

★★☆☆☆ Can only add one racer for motion. Very seldom does color Trax even work. If you only need lap time for one racer, then this is the app for you. This was used for HO slot car track.

★★☆☆☆ Go to work one time with two players no matter what I can do it will not work with two players it won't even open the goddamn camera no matter if you give it permission to every time there's a different problem
