About Stopwatch

Press Start to time and Lap to record a split without stopping the clock. The lap table shows each lap and the running total, with the fastest and slowest laps highlighted. On a computer, Space starts/stops and L records a lap.

The stopwatch is based on your device clock, so it stays correct if you switch tabs or reload the page.

FAQ
