1. 5/5Great tool for RC Race Practice!

   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!

2. 5/5Updates

   I’ve been using LapTracker for a while now, once used an speedometer when my motorcycle didn’t have one, and, now using it to count and track laps on my four lane HO scale slot car track. Just want to know, has there been any updates for LapTracker? Have not heard, seen, or received any text or email messages referring to updates for LapTracker, just curious, Thanks and have a good day, DDR.

3. 4/5Good lap counter and timer for the price

   I use this on my four lane 1/64 scale slot car layout. I use a cable from my IPad to on old computer monitor so everyone car see the screen. It is a little finicky but better than the expensive alternatives. I wish the screen would go landscape.

4. 5/5Perfect for slots

   I found out via forums & You Tube about this app being good for slot car hobbyist. And in deed it is. I use it every time I play with my set. Easy to use with many different settings. Makes racing more exciting & challenging timing your laps. Many thanks to Lap-tracker.

5. 5/5Great for Slot Car Lap Times

   Saved a bundle over diving headlong into an Arduino board, LCD, reed magnetic switches, tracking down someone who knows C++, and everything else it would have taken to set up a home made electronic lap timer for my slot car track. Instead, I dug some poster tack out of the junk drawer, and a juice glass out of the cabinet to hold my iPhone at the right angle, and paid $1.99 for an app. BOOM! Now I have an awesome lap timer. My brain is racing, thinking about all the things I can time, like my 5 year old running figure eights around our house chasing monsters on his Vtech watch, or how fast I run to the pantry and back when I’m making curry, because my misen place skills are crap and I never have everything I need at hand. If it moves, you can time it... this is sooooo good for my OCD, you have no idea.
