A one-minute timer is the quickest way to put a hard edge on a short task — long enough to matter, short enough that you actually finish. Press start and the full-screen countdown runs in your browser, accurate to the second even if you switch tabs, with an alarm when it hits zero.
What is a 1 minute timer good for?
- Holding a plank, wall-sit or stretch for a full minute
- A single slow-breathing or box-breathing reset
- Speed rounds in games, quizzes and classroom transitions
- Giving a child (or yourself) a one-minute warning before a change
How this 1 minute timer works
Press Start and the countdown runs full-screen in your browser; press it again to pause and resume, hit Reset to return to 1 minute, or +1 min to extend. You can also press the spacebar to start or pause. It is wall-clock accurate, so it stays correct even in a background tab, and it rings when it reaches zero.

Frequently asked questions
What can you actually do in one minute?
More than it feels like. One minute is the standard length for a plank or wall-sit, a round of fast push-ups, a single box-breathing cycle to calm down, or a quick tidy-the-desk sprint. Teachers use one-minute timers for transitions and speed drills; parents use them as a fair, visible warning before switching activities. Because this timer is wall-clock accurate it stays exact even if you glance away, and it rings so you do not have to watch the numbers.
Does the timer keep accurate time if I switch tabs?
Yes. Instead of counting ticks (which browsers throttle in background tabs), it records the exact end time and works out the remaining time from your clock on every update, so it is always correct. When you return to the tab the display instantly shows the true time left, and the alarm is scheduled through the Web Audio API so it still rings on time even while the tab is hidden.
Will it make a sound when it finishes? Is it free?
Yes to both. When the countdown reaches zero the timer plays an alarm tone and the card flashes with a “Time’s up” message, so you are notified even with the sound off — use the speaker button to mute or unmute. The first time you press Start the browser unlocks audio from that tap, which is why a timer you start yourself can ring later. It is completely free, runs entirely in your browser, needs no sign-up, and nothing is uploaded.
