What is a 1 minute timer?
A 1 minute timer is an online countdown that runs for exactly 1 minutes and alerts you when it reaches zero. This one is already set when the page opens: press Start or the space bar and it counts down from 01:00, keeps exact time if you switch tabs or lock your phone, and rings until you stop it.
What 1 minutes is good for
One minute is the unit of a lot of short tasks: a plank hold (beginners aim for 20–30 seconds and work up to a full minute), a 60-second elevator pitch, one round of a timed quiz, a child's turn with a toy, or waiting for a microwave dish to stand. Dentists recommend two minutes of brushing, so run this timer twice.
Because the countdown is so short, the display matters: it shows whole seconds, rounded up, and the last three seconds are easy to read on a phone held at arm's length. If you need something between one and two minutes, start and press +1 min once, then −1 min is available again.
Start it in one click
There is nothing to set: the time is loaded, the Start button has keyboard focus on a computer, and the alarm sound, volume and screen settings are remembered from your last visit. If you need a different length, type it into the hours, minutes and seconds boxes or pick another preset below the timer.
It keeps counting in a background tab
The end time is fixed the moment you press Start, so a slow or sleeping tab cannot make it late: whenever the page is drawn it recomputes the remaining time from the clock. The alarm is pre-scheduled on the browser's audio clock and backed by a system timer and a desktop notification, and if the device was asleep when the time came, the page rings as soon as you return and shows how long ago the 1 minutes ended. On iPhone keep the tab on screen, since Safari pauses hidden pages; Keep screen on, which is on by default on phones, prevents auto-lock while it runs.
Alarm, repeat and phone use
Choose Beep, Bell, Digital, Soft, Cuckoo, Chime, Pipe or None and set the volume; all but the cuckoo are generated in the browser and work offline, and the cuckoo is a short clip of about 65 KB fetched once and then kept by the browser. The alarm repeats until you press Stop alarm, Space or Esc, and gives up after 60 seconds. Android phones vibrate as well; iPhones on iOS 17 or later play it even with the silent switch on.
Need a slightly different time?
For a slightly longer job open the 3 minute timer; for something shorter, start this one and press −1 min to shave it down to the seconds you want after it begins, or type 0:30 into the seconds box before starting.
Other time tools
For measuring how long something takes, use the stopwatch, which counts up and records laps. For the days and hours until a date, use the countdown. For alternating focus and break periods, the Pomodoro timer runs the whole cycle, and the interval timer repeats work and rest rounds for training. They all share this timer's clock engine, sounds and settings.
