Tool guide
A countdown is for intervals you already know: 12 minutes for dough, 15 for a warm-up, 45 for a study block, an hour until a call. Type values into the Hours, Min and Sec fields or take a preset — 1, 5, 10, 15, 30 minutes or 1 hour — and the +1 min button stretches a running countdown on the fly. An alert sounds at zero, and the Sound button mutes it. It all runs in the browser, and the time you type is never transmitted. See also: pomodoro timer that keeps a session history, stopwatch for counting time upwards, sound test for speakers and headphones.
It is a plain countdown: one interval, one alert. There is no alternation of focus and breaks, no long break after the fourth round and no session history — that is what the pomodoro tool is for. In exchange you get an arbitrary duration up to 99 hours and the ability to add a minute mid-run.
Hours accept up to 99 and minutes and seconds up to 59, so roughly 99:59:59. In practice long countdowns are fragile: the tab gets closed, the laptop sleeps, the browser unloads the page from memory. For a reminder many hours away, a phone alarm or a calendar entry is far more reliable.
Elapsed time comes from the system clock, so the numbers stay correct. The sound is another matter: desktop browsers usually let a background tab play it, while phones with a locked screen often suppress it entirely. When the alert really matters, keep the tab in front of you.
Split it across fields: Hours 1, Min 30, Sec 0 gives 01:30:00. The same trick covers 75 minutes as 1 hour and 15 minutes. Alternatively, take the 1 hour preset, start it, and top up the remainder with the +1 min button as many times as you need.
Yes — that is what +1 min does: each tap adds a minute to the remaining time while the countdown keeps running. Reset does the opposite and restores the display to the value you entered. There is no way to shave time off a running countdown; reset it and enter a new one.
It goes back to zero. The state lives only in the open tab and is not restored after a reload or a close. For the same reason, the time you type is never stored or transmitted. If the tab is easy to close by accident, open the timer in a window of its own and leave it alone.
Three usual causes: the button is switched to Sound off, system or tab volume is muted, or the browser blocked autoplay because the page had no click after loading. Pressing Start counts as that click, so start the countdown by hand rather than by reloading the tab and walking away.
Before: Dough needs to rest for 12 minutes
After: Hours 0, Min 12, Sec 0 gives 00:12:00 on the display and an alert at zero
Before: Exactly 45 minutes for one chapter
After: The 30 min preset plus 15 in the Min field gives 00:45:00 as a single run
Before: The speech is capped at five minutes
After: The 5 min preset, with +1 min held in reserve for an answer that overruns
