About this tool

Full-featured online stopwatch and countdown timer. The stopwatch mode tracks elapsed time with centisecond precision and supports lap recording — each lap is saved with its timestamp for split-time analysis. The timer mode counts down from any duration with preset buttons for common intervals (1, 3, 5, 10, 15, 25, 30 minutes, 1 hour) and plays an audio alert when the timer reaches zero. Both modes feature large, easy-to-read displays with start, stop, and reset controls. Use it for workout timing, cooking, presentations, Pomodoro technique, and any time-tracking need.
