A classic 25-minute work, 5-minute break Pomodoro timer with start, pause and reset, adjustable intervals, a beep at the end of each phase and a session counter. Runs entirely in your browser.
How the Pomodoro Technique works
The Pomodoro Technique, created by Francesco Cirillo in the late 1980s, breaks work into fixed intervals — traditionally 25 minutes — each called a pomodoro, separated by a 5-minute break. After about four pomodoros you take a longer break of 15 to 30 minutes. The rigid structure works because a ticking, finite timer creates gentle urgency and makes it psychologically easier to start, which is usually the hardest part of any task.
This timer automates the cycle for you. When a work phase ends it beeps, flips to a break, and increments your completed-pomodoro counter; when the break ends it beeps again and returns to focus mode. You just keep working until you hear the tone.
Why short intervals beat marathons
Sustained attention naturally decays over long stretches, and pushing through it tends to produce diminishing, error-prone work. Fixed breaks reset your focus, reduce mental fatigue, and give your eyes and posture a rest from the screen. The break is not wasted time — it is what makes the next block productive.
The completed-session counter turns effort into a visible score. Aiming for a target number of pomodoros in a day is a simple, motivating way to measure real focused work rather than hours merely spent at a desk.
Getting the most from the timer
A few habits make the technique far more effective than just watching a clock count down.
- Pick one concrete task per pomodoro so the 25 minutes has a clear goal.
- Treat the timer as protected time — silence notifications and avoid task-switching until the beep.
- Actually take the break: stand up, stretch, or look away from the screen.
- Adjust the work and break minutes to suit deep work (try 50/10) or quick admin bursts.
- Use the session counter to plan a realistic number of focus blocks for the day.
Frequently asked questions
Can I change the 25 and 5 minute lengths?
Yes. Edit the work and break minute fields to any length you like — for example 50/10 for deep work or 15/3 for short tasks — then press Start.
What does the session counter show?
It counts how many work pomodoros you have completed since you last reset, so you can track your focused sessions across the day.
Does pausing lose my progress?
No. Pressing Pause freezes the current phase and the countdown; pressing Resume continues from exactly where you stopped.
Why isn't the beep playing?
Most browsers only allow sound after you interact with the page. Pressing Start counts as that interaction, so the end-of-phase beeps will play from then on.
Does the timer keep running in a background tab?
It continues, though some browsers throttle background timers slightly. Keeping the tab visible gives the most precise second-by-second countdown.
Is any of my activity tracked?
No. The timer is entirely client-side. Nothing about your sessions is stored on a server or sent anywhere.
