Overview
A stopwatch is an essential timing tool for athletes, coaches, students, cooks, researchers, and anyone who needs to measure elapsed time with precision. Our online Stopwatch provides a clean, easy-to-use timing interface with millisecond accuracy, lap recording, and split time tracking — features found on professional sports timing equipment. The Pomodoro work technique, interval training, exam practice, cooking timers, science experiments, and competitive gaming all benefit from precise time tracking.

It continues running even if you scroll or switch browser tabs (it uses the browser's high-resolution performance timer).
