Online timer, a countdown with an alarm.

Pick a preset or type any time, press Start, and an alarm rings when it reaches zero. The time left shows in the tab's title, the timer keeps going when you switch tabs, and full screen makes it big enough to read across a room. Handy for talks, recordings, workouts, cooking and classes.

Questions

Good to know.

Does the timer keep running in another tab?

Yes. It counts from the time it should end, not by ticks, and the alarm is set in advance on the browser's sound clock, so it rings on time even when the browser slows down pages in the background. Keep the tab open, and keep a phone's screen on, since phones pause pages that are not on screen.

Can I link to a set time?

Yes. Add ?t= to the address with the time, for example motionshine.com/tools/online-timer?t=10m, ?t=90s or ?t=1h30m, and the timer opens set to it.

I did not hear the alarm.

Check the volume here and on the computer, and press "Hear the sound". Browsers only allow sound after you click on the page, which pressing Start does.

Is there a stopwatch too?

Yes, the stopwatch counts up with laps, and the Pomodoro timer switches between work and breaks for you.

How long can the timer run?

Up to 99 hours. Long timers work as long as the computer does not go to sleep.
