A precision stopwatch for race day.

Sync Start is a mobile-first race stopwatch built for obstacle courses, track events, and any competition where many athletes start at the same instant but finish one by one. Instead of juggling multiple stopwatches or scribbling times on a clipboard, a single phone runs one master clock for the whole field. When a racer crosses the line, a tap records their finish, and the next one is ready instantly — with live ranks, splits, and podium colors as the heat unfolds.

It is made for the people standing at the finish line: coaches timing their squad, race officials running a meet, volunteers at a school field day, and clubs organizing obstacle races or time trials. Anyone who needs to start a group together and capture each person's time — without a second pair of hands or an expensive chip-timing system — can pick up Sync Start and run a clean heat in minutes.

Sync Start is built and maintained by the Sync Start team. We focus on a fast, reliable, distraction-free tool: a clock that keeps ticking if you switch apps, large tap targets for gloved hands, wake-lock so the screen never sleeps mid-race, and exports to Excel and CSV the moment a heat is done. Heats save to your account, organize into folders, and archive automatically — or pin a meet to keep it forever.
