Easy manual sports timing
RaceClocker is a do-it-yourself tool for manual timing of sports races. Our app offers an easy and fast alternative to chip timing or stopwatches. If you're a coach or race manager and you don't use transponders then RaceClocker is an excellent solution for high quality timing of your race.
Made for race managers and coaches
Central to cloud timing is our "RaceClock". This clock is running on our race server, making sure that all devices you use for timing are in synch. This results in precise manual timing from multiple devices for one and the same race. Timing accuracy is NOT depending on the speed of your internet connection.Learn more...
