Does the timer keep running in a background tab?

Yes. It is based on real timestamps, so the remaining time is correct when you come back even if the browser throttled the tab.

Can I reuse the same length quickly?

Yes. Presets start a new countdown with a single click, without retyping the numbers.

No. The timer works in any modern browser with no install and no account.

How to set the timer

Tap the large time display to enter hours, minutes and seconds, or pick a preset. Start begins the countdown, pause holds it and cancel resets it.

Popular countdown lengths

Common lengths have their own pages: 1 minute for quick tasks, 3 minutes for tea, 5 or 10 minutes for short study blocks, 15 to 30 minutes for workouts and cooking, and 60 minutes for longer sessions.

Timer with sound and notification

When time is up the selected alarm sound plays at your chosen volume. With notifications enabled you also get an alert while the tab is in the background.

Use the timer full screen

Full screen mode shows the countdown large enough to read across a room, and the display scale can be increased further.
