Live RaceClock
Central to cloud timing is synchronized clocks. This clock is running on our race server, making sure that all devices you use for timing are in synch. This results in precise timing from multiple devices for one and the same race. Timing accuracy is NOT depending on the speed of your internet connection.Learn more...

What race directors say
"My compliments to your product and service. I have used RaceClocker for several events, and I have to say - I LOVE IT! Your program has made timing rowing head races very easy. It is easy to use, accurate, and probably the best feature is live results."
Gregg Hartsuff
Head Coach University of Michigan Men's Rowing
"We have been using RaceClocker for the past 4 editions of our annual ADR Regatta. Over the years we have seen it develop into a reliable and easy to use timing solution at very low cost. Among others live results and split times are what rowers enjoy at our event."
Giovanni Margaroli
Race Director ADR Regatta
"Thanks for a wonderful tool. We started using RaceClocker recently for our annual events as an upgrade from stopwatches, pen and paper and Excel sheets. It works smooth, simple, intuitive, accurate and easy. We spend a lot less time on post-race calculation and the live results are a bonus."

RaceClocker's key features
Import start list
Upload an Excel or other CSV based start list to get going quickly. RaceClocker will group by category and for each participant you may include a bib number, name and club information. Sample file and instructions are provided.
Time anywhere
Your start, finish and split points can all be at different locations. RaceClocker is cloud based and centrally managed from the race managers dashboard. Timekeepers in the field can use any smartphone, tablet or laptop.
Correct mistakes
RaceClocker includes several features to recover from timing errors that happen with manual timing. Accidental timings can be 'undone' or assigned later to another participant. Time stamps from a backup system can be manually added at any time.
Time trial, waves and mass start
RaceClocker is great for time trial races where participants start one after another. Or for races where a wave or 'flight' of participants starts at the same time. Mass start races are also supported.
