A countdown that finishes on time
Type the hours, minutes and seconds you want and press start. The ring around the readout empties as the time runs down, so you can judge how much is left from across a room without reading the digits.
The countdown is stored as the moment it should finish, not as a number being decremented. That distinction matters: a decrementing counter falls behind whenever the browser throttles a background tab, and accumulates rounding errors every time you pause and resume. This one cannot drift, and pausing and resuming is exact.
Alerts that reach you
At zero it plays a sound and, if you have allowed notifications, shows a browser notification — so it still reaches you when you have switched to another tab or another application. Through the final minute the readout and its ring turn red and pulse, giving you a warning before the alarm rather than only at it.
You can turn the sound off in the Customize panel if you only want the visual alert. Reduce motion turns off the pulsing while keeping the colour change.
What it suits
- Cooking — eggs, bread proving, anything with a fixed time.
- Focus sessions — set 25 minutes and pair it with a soundscape from the speaker icon.
- Exams and presentations — full screen fills the display and hides every ad, so the room sees nothing but the countdown.
- Workouts — intervals and rest periods, up to 99 hours if you need it.
If you want to count up from zero and record laps instead, use the stopwatch.
