About this app

Transform your timing experience with our app, designed for racing enthusiasts, whether it's cars, karting, motorcycles, horses or any other competitive individual. Whether you're a professional or an amateur racing fan, this app allows you to time multiple racers simultaneously and share the results in real-time with other users trackside.

The app lets you precisely record lap times using simple push-button controls on the device itself or using an external Bluetooth input device. Each time a racer crosses the finish line, you can record the lap times for each competitor.

But what makes this app stand out is its collaborative connected timing feature. With the shared session feature, you can create or join a timing session with other users. Once connected, your timer not only tracks your own lap times but also syncs with other session members. Together, you can track the performance of multiple racers at once, creating a true live timing experience collaboratively, without the need for expensive transponders or other passive tracking devices.

Users within a session can view live lap times from all participants, providing a complete overview of the competition or training. The app automatically calculates the fastest laps and provides real-time statistics for each racer. This collaborative approach allows for comprehensive tracking of each racer’s performance during the race.

And for even broader visibility, live timing data can also be followed online in real time via Open Live Timing web application, allowing spectators, teams, and remote users to access the same live timing information directly from any web browser.
