Timer & Stopwatch

Set a countdown with an audible alarm, or time anything with a lap-recording stopwatch. Everything runs locally in your browser.

00:00

An alarm sounds when the countdown reaches zero. Keep this tab open.

Countdown

Great for cooking, workouts, presentations and the Pomodoro technique (try the 25-minute preset).

Stopwatch

Centisecond precision with unlimited laps and split times. Pause and resume any time.

Accurate

Both tools use timestamp-based timing, so they stay accurate even if the tab is briefly in the background.
