Frequently asked questions
How do I set a 30 minute timer?
It's already set: just press Start. You can change the hours, minutes and seconds at any time, or pick another quick time.
Will the alarm ring if I switch tabs?
Yes, as long as this tab stays open and Sound is on. Turn on notifications to also get a pop-up when time's up.
Does the timer keep running in another tab?
Yes. It's based on the clock, not on counting ticks, so it stays accurate even when the tab is in the background. Keep the tab open for the alarm to play.
Why didn't I hear the alarm?
Check that Sound is on and your device isn't muted. Browsers only allow sound after you've clicked the page, which pressing Start does.
Can I show it full screen for a class or meeting?
Yes. Press the full-screen button next to Reset; the numbers grow to fill the screen.
