Pomodoro Timer

What is the Pomodoro Technique?

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It uses a kitchen timer (originally shaped like a tomato, hence the name) to break work into focused 25-minute intervals separated by 5-minute breaks. After four pomodoros, you take a longer 15 to 30 minute break.

The system works because it externalizes the discipline of starting and stopping. Knowing a 5-minute break is coming makes a 25-minute sprint of focus feel doable. Most people who try the Pomodoro Technique are surprised by how much they get done in eight focused pomodoros (3 hours and 20 minutes of real work) compared to a typical "I worked all day but got nothing done" pattern.

How to use this timer

1. Pick one task. Choose a single task and type it into the focus field. One pomodoro, one task — no multitasking.
2. Choose a preset. 25/5 is the classic Pomodoro. Move to 50/10 or 90/20 once focused work is already a habit.
3. Start the timer. Press Start (or the spacebar) and work only on that task until the timer rings.
4. Take the break. When the chime sounds, step away from the screen. The break is part of the method, not optional.
5. Repeat, then rest longer. After four pomodoros the timer gives you a long 15 to 30 minute break. Then start a fresh set.

Why 25 minutes works

Twenty-five minutes is long enough to make real progress but short enough that starting never feels daunting — which is the hardest part of focused work. The fixed end point also fights "attention residue", the lingering pull of the last thing you looked at: a clear sprint boundary tells your brain that email and messages can wait until the break. And because the pomodoro is unfinished when the timer rings, the Zeigarnik effect keeps the task primed in your mind, so you drop back into it quickly after the break.

Which preset should you use?

25/5 (Classic) — the original Pomodoro. Best for getting started, for admin-heavy days, and for studying, where frequent breaks help retention.

50/10 (Deep) — once focus is a habit, a 50-minute block wastes less time on spin-up. Good for coding, design, and writing.

90/20 (Ultra) — roughly one ultradian cycle. Reserve it for your deepest, lowest-interruption work and protect the 20-minute break.

Common Pomodoro mistakes

• Working through the break — it is what keeps the day sustainable.
• Stacking several tasks into one pomodoro instead of one focused task.
• Spending the break on a screen, which never lets your attention reset.
• Counting interrupted or half-hearted sprints as completed pomodoros.
• Skipping the long break after four sessions and burning out by mid-afternoon.
