About the Countdown Timer
The Countdown Timer counts down from minutes and seconds you set and plays an alert sound when it reaches zero. It suits cooking, workouts, study sessions, presentations and quizzes.
The timer measures real elapsed time using your device clock rather than counting ticks, so it stays accurate even if the page is briefly slowed down. Browsers may throttle tabs that are in the background, so for critical timing keep the tab visible and turn the device volume up for the alert.
How to use it
- Enter minutes and seconds.
- Press Start.
- Pause or reset whenever needed.
- Wait for the sound when the time is up.
Tips and good to know
- Keep the tab open; some phones stop sound when the screen is locked.
- Try the Pomodoro method of 25 minutes of focus followed by a 5-minute break.
- Use the Stopwatch to measure how long a task actually takes.
