How to use the Pomodoro timer

Step 1: Pick a mode

Click one of the three tabs above the time: Pomodoro for focus, Short Break for a quick reset, or Long Break for a longer recharge. The time updates to match the chosen mode.

Step 2: Start the session

Press Start (or hit Space). The countdown begins, and the remaining time syncs into the browser tab title so you can keep working in another window without losing track.

Step 3: Pause, resume, reset

Press Pause (same button, or Space) to hold the countdown without losing progress. Press it again to continue from the same remaining time. Reset (or R) returns the current mode to its full duration.

Step 4: Let the alarm tell you to switch

When the session ends, the alarm plays and the tab title flashes. The timer auto-advances: Pomodoro → Short Break, or Pomodoro → Long Break after every 4 Pomodoros. The four dots below the time show your current cycle position.

Customize to your rhythm

Click the settings icon to change any duration, pick a different alarm sound, set how many times the alarm repeats, or toggle the automatic long break. All settings persist in your browser's localStorage.

Keyboard shortcuts (desktop)

What is the Pomodoro Technique?

The Pomodoro Technique is a time management method invented by Francesco Cirillo in the late 1980s, while he was a university student. He used a tomato-shaped (pomodoro in Italian) kitchen timer to structure his study sessions, and found that committing to a short, non-negotiable block of focus was more sustainable than open-ended cramming.

The core rules are simple:

1. Pick a task.
2. Work on it, and only it, for 25 minutes. This is one Pomodoro.
3. When the timer rings, take a 5-minute short break. Stand up, look out the window, grab water.
4. After every 4 Pomodoros, take a longer 15-30 minute break. This is when real recovery happens.

The trick is that each Pomodoro is indivisible: if you get interrupted, you either defer the interruption or start the Pomodoro over. That friction is what trains you to protect focus time.

Why the Pomodoro Technique works

• Fights decision fatigue. "I'll stop when I feel like it" is a decision you have to keep re-making. A 25-minute timer is one decision up front.
• Makes procrastination small. Starting an 8-hour writing project is terrifying. Starting one 25-minute Pomodoro is not.
• Protects attention. The timer is a visible commitment: no email, no Slack, no just-checking-one-thing until it rings.
• Schedules recovery. Most people know they should take breaks. Almost no one takes enough on willpower alone. The Short Break is non-optional.
• Exposes your real capacity. Counting Pomodoros per day is a blunt but honest measure of how many hours of actual focus you got - usually a lot less than you think.

When to use a Pomodoro timer

Deep work & writing

Essays, research papers, code reviews, long-form writing - anything that needs 90 minutes of continuous attention and collapses the moment you check email. Stack 3-4 Pomodoros back-to-back in the morning before the day's interruptions start.

Studying & revision

Block subjects into Pomodoros: one for biology vocab, one for math problems, one for history notes. Label the break as "walk" or "stretch" so you actually leave the desk. For exam prep, track completed Pomodoros like practice reps - the count is a more honest signal than "hours studied".

Programming & debugging

Debugging especially benefits: a bounded 25-minute sprint forces you to either solve the bug or surface the fact that you're stuck and need a break / different approach. Engineering fatigue is real; the Long Break is when subconscious pattern-matching actually happens.

Creative work

Drawing, music practice, design iteration. A fixed timebox sidesteps perfectionism - finish something in 25 minutes, then step back and evaluate during the break.

Admin tasks & email

Batch email, invoicing, expense reports, form-filling into a single Pomodoro rather than letting them bleed through the day. The timer becomes a lid on low-value work.

ADHD & focus-challenging work

Many people with ADHD find the structure of fixed intervals much easier to engage with than open-ended "just work on it" instructions. A 15- or 20-minute Pomodoro (customize in settings) can be a gentler starting point.

Pomodoro vs regular timer vs stopwatch

• A Pomodoro timer cycles between focus and rest automatically. Use it when you want to sustain work across a full day without burning out. This page.
• A countdown timer counts down once from a duration you set. Use it for one-off countdowns - cooking, workouts, a single focus block.
• A stopwatch counts up from zero. Use it when you want to measure how long something actually takes.

Rule of thumb: if the task is "work for a few hours and don't fry my brain", Pomodoro. If the task is "tell me when 15 minutes are up", the timer. If the task is "how long did that take?", the stopwatch.

Tips & tricks

• Actually leave the desk on breaks. A "short break" spent doomscrolling on the same screen doesn't recover the same attention a real walk does.
• Plan the first 30 seconds. Before pressing Start, decide exactly what you'll type or open. Starting fast prevents the Pomodoro from evaporating into setup.
• Guard the Long Break. The 15-30 minute break after 4 Pomodoros is the one most people skip. It's also the one the whole rhythm depends on.
• Count, don't judge. Log Pomodoros per day as a number, without grading them. 5 honest Pomodoros in a day is already a strong week's worth of focus.
• Customize the durations. 25/5/15 is a starting point, not a law. Many writers prefer 50/10/30. Many ADHD'ers prefer 15/5/20. The best Pomodoro is one you actually finish.
• Go fullscreen for group sessions. Run the page fullscreen on a second monitor or shared screen during coworking calls and silent-study sessions.
• Pick a calm alarm. Radar and Digital are loud and attention-grabbing; Chime and Gentle are softer and less disruptive if you share the space.
