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. ### 4/5 — Slot cars *2025-03-30, version 4.0.1* Hi all, I use LapTracker for slotcar timing and it’s great but I’d love more options too.. ### 5/5 — Slot Car Track *2025-03-25, version 4.0.1* Best bang for your buck easy setup ### 3/5 — Great when working *2025-02-08, version 4.0.1* I’ve been using LapTracker for Scalextric racing, for a while now and it’s mostly good. Sometimes though the camera either sees nothing or records a time for both lanes even though only one car has passed. Adjusting the sensitivity doesn’t help. Another feature that would be great would be to choose different colours for different lanes. I have red and blue controllers - I’d love to colour the lane ids red and blue too. ### 5/5 — Amazing *2025-01-08, version 4.0.1* You have to figure it out a bit at the start, but this app works great and detects the cars really easily. worth your money. ### 5/5 — Slot car racers *2024-12-06, version 4.0.1* The best for a four lane track, no wiring involved just set, calibrate, and race. Hats off to the developer, simple and fun! ### 5/5 — Lap tracker 👍👍 *2024-11-24, version 4.0.1* I purchased lap tracker to use with my HO slot cars and it works fantastic. I’ve mentioned it numerous time on slot car groups and it gets a very high rating from other users too. Thanks it’s a great app. ### 4/5 — Good lap counter and timer for the price *2024-10-07, version 4.0.1* 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. ### 5/5 — Updates *2024-09-12, version 4.0.1* 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. ## Frequently asked questions about LapTracker ### What does LapTracker do?
