A free online countdown timer that just works

A countdown timer is the simplest productivity tool there is: you decide how long something should take, you start the clock, and you get told when the time is up. That small act of committing to a duration is what makes it powerful. Instead of working until you drift off, or checking the oven every two minutes, you hand the job of watching the clock to something that will not forget.

This countdown timer runs entirely in your browser. There is nothing to install, no account to create and no trial that expires. Open the page, type the hours, minutes and seconds you need, and press start. It works the same on a laptop at work, a tablet in the kitchen and a phone at the gym, and it stays free because the site is supported by advertising rather than subscriptions.

What you can do with it

Set any duration

Enter hours, minutes and seconds directly — anything from a single second up to 99 hours, 59 minutes and 59 seconds. Values larger than 59 roll over on their own, so typing 90 into the minutes box becomes 1 hour 30 minutes.

Choose how it alerts you

Eight built-in sounds — Bell, Chime, Alarm, Digital, Gong, Cat, Synth and Buzzer — with a volume slider and a preview so you can hear each one before you commit. Mute it entirely if you need a silent countdown.

Name your timer

Give the countdown a label such as "Bread proving" or "Draft the report". The name appears above the clock and is saved with the entry in your history, which matters once you are running several timers in a day.

Labelled in the tab and the address bar

Setting a duration renames the browser tab to match it — "25 Minute Countdown Timer" — and rewrites the page address to the same timer. A crowded tab bar stays readable, and the link you copy reopens exactly what you set.

Reuse recent timers

Finished countdowns are collected in a history panel beside the clock. Reopen a duration you used yesterday instead of typing it again.

Bookmark a preset

Common durations have their own web address — a 25 minute Pomodoro sits at /countdown-timer/pomodoro/25m. Bookmark it, pin it to your home screen, or send the link to a colleague and it opens ready to go.

How people actually use a countdown timer

The tool is deliberately generic, but the reasons people reach for it fall into a few familiar groups.

Focused work and study

The best known method is the Pomodoro technique: work for 25 minutes, take a five minute break, and after four rounds take a longer one. The countdown does the enforcing, which is the part willpower is bad at. Longer blocks of 50 or 90 minutes suit deep work — writing, coding, revision — where the cost of being interrupted is high. Students use fixed durations to rehearse exam sections under realistic time pressure rather than guessing how long a question is taking.

Cooking and the kitchen

Eggs are the classic case: roughly six minutes soft, eight medium, ten hard. Beyond that, steeping tea, resting a steak, proving dough, boiling pasta to al dente and pulling a pizza out at the right moment are all jobs where thirty seconds either way is the difference between right and ruined. A timer with a clear audible alert is more reliable than a mental note taken while doing three other things.

Training and exercise

Interval training depends on honest timekeeping — a Tabata round, a plank hold, ninety seconds of rest between heavy sets. Counting in your head almost always cuts rest short when you are tired. Setting the duration once and letting the alert decide keeps a session consistent from the first set to the last.

Everyday life

Hair dye and face masks come with instructions measured in minutes. Meetings run long unless someone is watching the clock. Children respond better to a visible timer than to being told "five more minutes" twice. Screen time, laundry cycles, meditation and the twenty seconds you are meant to spend washing your hands all benefit from the same simple mechanism.

Timer lengths and what they are good for

You can enter any duration you like, but in practice most people reach for the same handful of lengths. If you are not sure where to start, pick the nearest row below, set it, and adjust once you have seen how it feels in real use.

Under five minutes

DurationTry it for
20 secondsWashing your hands properly — the length health guidance actually asks for, and far longer than it feels.
30 secondsA plank hold, a sprint interval, or letting a coat of something set before the next one.
1 minuteA turn in a board game, rest between light sets, or a one-minute answer you are rehearsing for an interview.
2 minutesBrushing teeth for the full dentist-recommended time, a cold shower you would otherwise cut short, or an IELTS speaking answer.
3 minutesSteeping green tea before it turns bitter, or a short round of breathing exercises.

Five to twenty minutes

DurationTry it for
5 minutesA quick bodyweight workout or HIIT round — long enough to be worth doing, short enough that you will not talk yourself out of it. Also the standard Pomodoro short break, resting a steak, and a fair warning before a child has to stop playing.
10 minutesReading. Ten minutes is the length people most often commit to when building a daily reading habit, because it survives a busy day. Equally good for meditation, a hard-boiled egg, or a stretching routine.
15 minutesCooking — roasting vegetables, baking cookies, simmering a sauce down. It is also the Pomodoro long break, a face mask, and about the right length for a stand-up meeting that would otherwise sprawl.
20 minutesA power nap short enough to avoid grogginess, rice on the hob, or a focused brainstorming session before ideas start repeating.

Twenty-five minutes and up

DurationTry it for
25 minutesThe classic Pomodoro work block. Four of these with short breaks between them, then one long break, is the whole method.
30 minutesLanguage practice, an email sprint to clear a backlog, hair dye that specifies a development time, or a yoga session.
45 minutesA longer reading block, gardening, or a laundry cycle you would rather not forget about.
1 hourA study session, meal prep for the week, music practice, or protected time for creative work.
90 minutesDeep work. Ninety minutes lines up roughly with a natural cycle of alertness, which is why it turns up so often in advice about concentration.

None of these are rules. The value of a countdown is not that fifteen minutes is the correct amount of time to roast vegetables — it is that you decided on a number, and something other than your memory is now responsible for it.

Why the timing stays accurate

Many browser timers drift because they count ticks, and browsers throttle background tabs to save battery. This one avoids the problem: when you press start it records the exact clock time at which the countdown should reach zero, then works backwards from your device clock. Switch tabs, open another app or lock your phone and the remaining time is still correct when you come back.

One honest caveat: while a tab is hidden the browser may stop redrawing it, so the digits on screen can appear to pause and then jump to the right value when you return. The underlying time is never lost — only the picture is delayed.

  • End time is fixed at the moment you press start, not recalculated frame by frame.
  • Pausing stores the exact remaining milliseconds, so resuming does not round your time away.
  • Your recent timers are stored in your own browser, on your device, and are never uploaded.

Frequently Asked Questions

Is this countdown timer really free?
Yes. Every timer on this site is free to use, with no account, no sign-up, no trial period and no feature locked behind a payment. Open the page, set a duration and press start. The site is supported by advertising, which is what keeps the tools free for everyone.
Do I need to install an app or create an account?
No. The countdown timer runs entirely inside your browser, so there is nothing to download and nothing to install. It works the same way on Windows, macOS, Linux, Android and iPhone — if the device has a modern browser, the timer works.
Will the timer keep accurate time if I switch tabs or use another app?
Yes. When you start a countdown, the timer records the exact clock time at which it should finish rather than counting frames. If you switch to another tab, minimise the window or lock your phone, the remaining time is recalculated from the system clock the moment you return, so it will not drift or fall behind. Note that browsers slow down background tabs, so the on-screen digits may pause while the tab is hidden and then jump to the correct value when you come back.
Does the countdown timer make a sound when it finishes?
Yes. You can choose from eight built-in alert sounds — Bell, Chime, Alarm, Digital, Gong, Cat, Synth and Buzzer — using the speaker icon next to the timer. There is a volume slider from 0 to 100 percent, and tapping a sound plays a preview so you can pick one before you need it. You can also mute the alert entirely if you prefer a silent countdown.
How long a countdown can I set?
Anything from a single second up to 99 hours, 59 minutes and 59 seconds. If you type a value larger than 59 into the minutes or seconds box it rolls over automatically, so entering 90 minutes becomes 1 hour 30 minutes. Short countdowns suit cooking, breathing exercises and rest between sets; longer ones suit deep work blocks, exams, laundry cycles and slow-cooked meals.
Can I bookmark or share a specific timer?
Yes. Preset timers have their own web address — for example a 25 minute Pomodoro lives at /countdown-timer/pomodoro/25m and a five minute timer at /countdown-timer/5-minute. Bookmark that link, put it on your home screen or send it to someone else, and it opens preloaded with the right duration. No setup is needed on the other end.
Is my timer history private?
Your recent timers are saved in your own browser using local storage, on your device only. That history is never uploaded to a server and we cannot see it. It keeps up to 50 recent entries per tool, you can delete individual entries or clear the whole list from the sidebar at any time, and clearing your browser data removes it completely.
Does the countdown work offline?
The page needs an internet connection to load the first time. Once it is open, the countdown itself runs locally in your browser and does not need to talk to a server to keep counting, so a brief drop in connectivity will not stop a timer that is already running.
When should I use a countdown timer rather than a stopwatch?
Use a countdown whenever the deadline matters more than the measurement. If something will burn, over-steep or over-develop, if a talk has to fit a fixed slot, or if you have committed to working for a set number of minutes, the countdown is doing the one job you cannot reliably do yourself: watching the clock while you are busy with something else. If instead the end point is not decided in advance, and what you actually want is a number at the finish, that is a job for the stopwatch.
Why did my alert sound not play?
Most browsers block audio until you have interacted with the page, which is why the sound is generated after you press start rather than on page load. If you hear nothing, check that the speaker icon is not muted, that the volume slider is above zero, and that your device is not on silent. Tapping a sound name in the settings panel plays a test tone so you can confirm audio is working before you rely on it.
