A Pomodoro is a 25-minute block of single-tasking focus, the core of the Pomodoro Technique. Start this 25-minute timer, work on one thing until it rings, then take a short break — and after four Pomodoros, a longer one. It runs full-screen in your browser and stays accurate even in a background tab.
What is a pomodoro timer good for?
- One focused 25-minute work or study sprint (one “Pomodoro”)
- Pairing with a 5-minute break, then repeating
- Beating procrastination by committing to a single block
- Protecting deep work from notifications and task-switching
How this pomodoro 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 25 minutes, 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. Need a different length or a stopwatch and date countdown? Open the full timer.
Frequently asked questions
What is the Pomodoro Technique?
The Pomodoro Technique, created by Francesco Cirillo, breaks work into 25-minute focus blocks called Pomodoros, each followed by a short 5-minute break; after four Pomodoros you take a longer 15–30 minute break. The rules are simple: during a Pomodoro you work on one task and resist every interruption, and if a distraction is unavoidable you end the Pomodoro and start fresh. The fixed 25-minute length is short enough to commit to even when you do not feel like starting, which is what makes it so effective against procrastination. This timer gives you the 25-minute block; start it, silence your phone, and work until it rings.
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.
