I can't find the LapMonitor app on Appstore or Playstore:

LapMonitor Apps are FREE but are right now on invite only

Once you have bought your LapMonitor or a transponder you will receive a mail from Apple to install the App or a link on google Playstore for Android users

LapMonitor apps are compatbile with the following smarphone/tablet

  • Iphone 4S,5/6/7/8/X, Ipad 3/4, Ipad mini 2/3/4, ipad Air/Air 2 (with IOS 9,10 or 11)
  • Android 5.0 or higher with Bluetooth 4.0 or higher

Apps will be avaible for download directly on the stores in the coming weeks

How it works

Here is short video that explain how LapMonitor works:


Does the LapMonitor support multiple cars passing side by side ?

Which connector type for your transponder ?

The transponder with JR connector can be powered directly by your receiver

The transponder with the Molex connector can be powered by 

  • a 1S/2S LiPo battery with 2 PIN Molex 51005 connector
  • your car/motorbike receiver using the Molex to JR adapter
For 1:8 IC, we recommend  the transponder with Molex connector that very versatile and fast to install on the car body
