LapTracker - Auto Timer

I am getting back into HO scale slot car racing after a 45year hiatus. I found some lap counter/timer systems that cost as much as $200 or more and use old technology. I’m glad I came across a YouTube video that suggested this app.

I got this app to try with a portable slot car track. I was a bit skeptical, but it actually works fantastic. My only gripe is that I wish it could display in landscape mode. Other than that I think it’s great.

The best for a four lane track, no wiring involved just set, calibrate, and race. Hats off to the developer, simple and fun!

Great tool for testing cars and running trials. Ran a few multi-lane events. Ghost and shadow counting occurs regularly. With and without the phone flashlight. Tried the LED light bead as well. Limited improvement. Like to be able to save and send data too. Features been inactive since I downloaded. Great app for the $$$$.

Tested with Turbo Racing, Kyosho Mini-Z, and Losi Mini B. Works great. Tons of adjustability and settings. Voice call out works very well. Takes less than a minute to get it setup and running.

The app works flawless on an HO slot car track. This app has all the needed info to set it up properly to get it to work.

I use this to tune my cars. I can determine on my home track when I’m tuned properly to be competitive at the club.

Used this today to work on improving my lap times at my local RC track. Put my phone on a little bendy tripod pointed across the start/finish line and set the zone height to cover the whole width of the lane. I wasn’t sure if the spoken lap times would work with bluetooth but was pleasantly surprized to hear the lap number and time spoken through my airpods up on the driver’s stand. Excited to try the “Stop after X Time” and “Finish Last Lap” options to simulate a 5 minute qualifier or Main next time I use this. Of course, the timing only worked accurately because I was the only one on the track - multiple cars passing through the timing zone would have completely messed up the timing. Sure you can set multiple timing zones or “lanes” but this only really works for slot-cars, hotwheels or other activities where the object being timed stays in a specific lane on every pass. RC cars and their drivers are far less predictable. Still, for the price and what i needed this for it works great!

Simple to setup and use. Would recommend

This works great for slot car lap counting. Simple to use, easy to set up on a tripod with phone. It is light sensitive so be sure your in a well lighted area and not casting light/shadows as you walk by or around the track. Set it up in an easy to reach spot. $200.00 cheaper than the in-track unit although not as in depth, not that you really need one of those at a home family track.
