What is Timer & Stopwatch?

Timer & Stopwatch is a free online tool for time management and measurement. In timer mode, an alarm notifies you when the set time is reached, useful for time-limited activities like cooking, exercise, and studying. In stopwatch mode, you can precisely measure elapsed time and record lap times, useful for exercise tracking, work time measurement, presentation rehearsal, and more. No app installation required—use instantly in your web browser, and it works in the background.

How to Use

1. Select 'Timer' or 'Stopwatch' from the top tab.
2. Timer: Set the time and click the start button to begin countdown. An alarm sounds when time is up.
3. Stopwatch: Click the start button to measure elapsed time. Use the 'Lap' button to record split times.
4. Pause and resume functions let you stop and restart at any point.

Tips

Background execution is supported so the timer works even if you close the browser tab. Allow browser notification permission to hear alarm sounds. Stopwatch lap time records reset when you refresh the page, so save separately if needed.
