A very reliable, affordable and easy to install lap counter. Customer support is also very helpful. I can only recommend this system. ### 5/5 — Indispensable *2026-05-22, version iOS App Version 1.4.6* Vraiment top avec une oreillette ### 5/5 — Le produit ! *2025-11-19, version 1.4.1* Excellent produit! Solution simple et efficace. L application est très claire et super stable. Je recommande fortement ! ### 5/5 — Perfect for Backyard Rc Racing *2024-10-24* The LapMonitor is every handy rc arsenal tool when *Chollas Racing Team* have a Backyard Rc Racing Event. The small package as a kit and portability I can take it anywhere set it up easly/quick and have everyone start Rc Racing to the finnish line. All the Rcer’s I know have a transponder loves the price also the different types of transponder to choose from. Highly recommend to anyone used LapMonitor for Backyard Rc Racing Event or used it for personal practice track time. Also customer service is on point 5star no doubt. ### 5/5 — So much fun!! *2024-10-03* Ordered the LapMonitor device and we’ve been using it for the last few weeks at our rc hookups. So much fun to hear your lap times, best times, race leader etc announced via a Bluetooth speaker! This app stores and displays race data from the LapMonitor in real time. Works perfectly. Thanks for creating such a fantastic device and app! ### 5/5 — Brilliant bit of kit and app *2024-04-04, version 1.4.1* I have a local track I can use for practice but without being able to monitor lap times it’s hard to see if you’ve made any improvement. With the Lapmonitor you have live timing helping you to dial in your setup and see what really does and doesn’t help you go faster. You can use the Lapmonitor for full race simulations too if others have a Lapmonitor transponder. ### 5/5 — Awesome product and great customer service *2024-02-27, version 1.4.1* Reached out to LapMonitor about some parts and technical help and customer service was excellent. I had a kinda weird request and was surprised that they went the extra mile to help. Product works great and is an awesome tool for tuning on practice or race day. ### 5/5 — Excellent *2023-11-29, version 1.4.1* Je trouve ce système Lapmonitor excellent. En effet désormais, n’importe où, on peut installer son Lapmonitor au bord de la piste avoir ses chronos. Le gros plus pour moi, c’est d’entendre en direct, à chaque tour, ses chronos. Le système est très simple à mettre en route. L’appli est très intuitive et très facile à utiliser. Si vous cherchez un système de chronométrage personnel, n’hésitez pas une seconde. De plus le service clientèle est tres réactif et sérieux. ### 5/5 — Outstanding! *2023-07-03, version 1.4.1* Well where do I begin, Very fast delivery to the U.K. and such helpful customer service. The LapMonitor system and transponders work brilliantly together. The app is easy to use and understand. Absolutely love the product and app! Keep up the great work. We just need a hobby shop in the U.K. to stock them. ### 5/5 — Système de comptage *2023-06-06, version 1.4.1* Très bon système de comptage pour voiture radio commandé, performant, permet de rouler seul et de regarder ses propre chronos sur la durée définie, parfait pour les entraînements, perfectionnement et essais de réglage châssis pour observer les différences de performance obtenus. ## Frequently asked questions about LapMonitor ### Does LapMonitor have ads?
