What makes it different
An alarm that rings on time, even in a background tab
The alarm is scheduled the moment you press start, so it still goes off on time when the browser slows down tabs you are not looking at.
Full screen
Put the countdown on a meeting room display or a classroom screen.
Shareable links

No install, no sign-up
Everything runs in your browser, and nothing you enter is sent to a server.
Frequently asked questions
Does the alarm ring if I am in another tab or another app?
On a computer, yes. If you close the tab the timer is in, the alarm goes with it.
What happens if I turn off my phone screen?
While the timer is running, the page asks the browser to keep the screen on. If you turn the screen off yourself or switch to another app, the phone pauses the browser and the alarm may not sound. On a phone, keep the screen on.
I can't hear the alarm.
Check your device volume and silent mode first. Browsers only allow sound after you press a button, so the alarm is scheduled when you press Start yourself.
Does pausing and resuming throw the time off?
No. When you resume, the end time is recalculated from the time that was left.
