Features

  • Hours, minutes and seconds, or one-tap presets from 30 seconds to an hour.
  • +1 min adds a minute while it runs — for when the pasta needs longer.
  • A repeating alarm at zero, and an optional overtime count-up so you know how late you are.
  • Restart automatically for repeating reminders, and optional spoken warnings at one minute and ten seconds.
  • The end time is shown on the display, the tab title counts down, and the timer survives a reload.

Timers by length

Questions

Will the alarm sound if the tab is in the background?

Yes, as long as the tab stays open and your device isn't asleep. Browsers only allow sound after you've interacted with the page, so press Start yourself rather than relying on a bookmark to start it.

Can I set a timer for more than an hour?

Yes — enter hours, minutes and seconds directly. The timer handles up to 99 hours.

What does overtime do?

With Count overtime on, the display keeps counting after zero in red, so you can see exactly how long it has been since the timer ended.

Does the countdown keep going if I refresh?

Yes. The end time is saved on your device, so a reload shows the correct time remaining.
