Set a countdown, hear it end

Type a length or take a preset. The timer starts immediately, keeps its accuracy while you work in another tab, and makes a sound when it reaches zero.

Presets for the lengths people actually set

Five minutes, a pomodoro, an egg, a plank, a nap that stops before deep sleep. Each preset has a page of its own that starts counting the moment it opens, so a bookmark is a one-click timer rather than a form to fill in again.

It finishes even when you are not looking

The sound plays on completion and the tab title counts down, so a timer running behind a full-screen window is still legible from the tab strip. What it cannot do is reach you once the tab is closed — no web page can, and a page that implies otherwise is wrong.

Questions

Do the timers keep running if I switch tabs?

Yes. The countdown is measured against a monotonic clock rather than counted in ticks, so a backgrounded tab, a throttled timer or a laptop lid closing does not lose time — when you come back it shows what it should, not what it managed to count.

Does a timer survive a daylight-saving change?

Yes, and the distinction matters. A countdown measures elapsed real time, so a timer set for six hours across a spring-forward still runs six real hours even though the wall clock advances seven. An alarm set for a wall-clock time does the opposite: it fires when the clock says so, which is what you want from an alarm.

Will an alarm go off if I close the tab?

Not on its own — a closed tab runs no code, and any site claiming otherwise is relying on a notification permission you granted earlier. An alert that reaches you with everything closed is scheduled on our servers, and that is the one thing here a membership pays for.
