Set any time from a few seconds to many hours and this countdown timer counts down in large digits with a progress ring. When it reaches zero it plays an alarm sound and shows a clear message. Quick buttons start a 1, 2, 3, 5, 10, 15, 20, 30, 45 or 60 minute timer with one tap.
The remaining time is shown in the browser tab title, so you can work in another tab and still see it. Turn on Restart automatically to use it as an interval timer for workouts or study breaks, or go full screen for a classroom or meeting.

Tips for using an online timer
Press Start once with sound turned on: phones only allow web pages to play sound after you tap the page, and the Start button takes care of that. Keep your device volume up and the page open (it can be in the background).
The timer calculates the finish time when you start, so it stays accurate even if the browser slows down background tabs. On phones, the timer asks the system to keep the screen on while it runs, where the browser supports it.
Frequently asked questions
Will the alarm ring if the tab is in the background?
Yes, as long as the page stays open and your device is not muted. On some phones, sound may be held back while the screen is locked, so keep the screen on for important timers.
How do I set a timer for more than an hour?
Type the hours in the Hours box, for example 1 hour 30 minutes. Any length up to 99 hours works.
Can I use it as an interval timer?
Yes. Tick Restart automatically and the timer starts again each time it reaches zero, with an alarm at every round.
Is there a timer for studying?
Try the pomodoro timer, which switches between 25-minute focus sessions and short breaks automatically.
