Pomodoro timer

25 minutes of focus, 5 minutes of break, repeat. The hourglass auto-advances through every phase so you can keep your head in the work.

Total session: 115 min

The long break is configurable for when you run a second set; this session ends after the final focus block.

What is the Pomodoro Technique?

The Pomodoro Technique was developed in the late 1980s by Francesco Cirillo, an Italian university student who couldn't get more than a few minutes of work done before his attention drifted. He grabbed a tomato-shaped kitchen timer - pomodoro is Italian for tomato - set it to 25 minutes, and committed to working until it rang. Out of that small experiment grew one of the most widely used productivity methods in the world.

The shape of the technique is simple: 25 minutes of focused work, then a 5-minute break, repeated four times, then a longer 15-30 minute break. Two ideas make it work. First, 25 minutes is a sustainable concentration window - long enough to make real progress, short enough that almost anyone can ride out the urge to switch tasks. Second, the breaks are not optional rest; they let the focused mind reset so the next block can be fresh. Skip the breaks and the technique stops working.

The three phases

Each phase has a different job. Treating them as the same thing is the most common reason Pomodoro stops working.

  • Focus - 25 min

    One task, no switching. The whole point of the focus block is that you commit to one thing before you start, and you don't change your mind mid-block. If a stray thought arrives, write it on a notepad and keep going.

  • Short break - 5 min

    Stand up, look at something far away, drink water, stretch your shoulders. Five minutes is long enough for the brain to switch modes; not long enough to fall down a feed. Avoid screens during the break - that defeats the rest.

  • Long break - 15 min

    After every fourth focus cycle, take a longer break. Step outside, eat something, talk to a person, lie down. The long break clears the cache so the next set of cycles starts with full attention again.

When the Pomodoro timer earns its keep

Reach for Pomodoro whenever the work is shapeable but you keep getting pulled away from it. It is especially useful when you need to:

  • Make real progress on knowledge work - writing, coding, design, analysis - without checking your phone every few minutes.
  • Break a procrastination spiral. The commitment is only to the next 25 minutes, which is a much smaller deal than committing to "the whole project".
  • Study for an exam - the focus-rest rhythm matches how memory consolidates better than a single long session.
  • Pace a coding session so you do not burn out by hour two and produce nothing usable for the rest of the afternoon.
  • Build a daily writing habit - three or four cycles a day adds up to a meaningful word count without ever feeling heroic.

How to use it

A handful of taps and you are off:

  1. Pick one task before you press start. Be specific - "draft the introduction" beats "work on the report".
  2. Eliminate the obvious distractions. Close unrelated tabs, silence notifications, put the phone face-down somewhere you cannot see it.
  3. Start the timer. Work on that one task until the focus phase ends. If you finish early, use the remaining time to review or polish what you just made.
  4. Take the break. Stand up, walk a few steps, drink water. Resist the temptation to check messages - the rest is doing real work for you.
  5. Repeat. After four cycles, take the long break. After two long breaks in a day, you are at the upper end of what most people can sustain - anything more becomes diminishing returns.

Frequently asked questions

What if 25 minutes is not enough?

Try the Flowtime preset (50/10/30 × 3) for longer focus blocks. Some people genuinely need 50 minutes to settle into a hard problem. The trade-off is that longer blocks need more discipline to protect - interruptions hurt more, and the rest in between has to be longer to clear the load. If 25 feels too short and 50 feels too long, try 35 or 40; nothing about Pomodoro is sacred about the exact number.

Should I really take the breaks?

Yes. The breaks are not a polite afterthought - they are doing load-bearing work. Skipping them means the next focus block starts with a tired brain, and quality drops fast. People who try Pomodoro and conclude it does not work for them are almost always the people who skipped the breaks. Try it as designed for a week before changing anything.

What if I am interrupted mid-Pomodoro?

The orthodox Cirillo answer is that the Pomodoro is voided - you stop the timer, handle the interruption, and start a fresh 25 minutes. The pragmatic answer is to pause the timer, deal with the interruption, and resume where you were. Both are fine; pick the rule that keeps you actually using the technique. What matters is not letting interruptions accumulate without notice.

Why four cycles before a long break?

Four 25-minute cycles plus their breaks comes out to roughly two hours, which is close to the body's natural 90-minute ultradian rhythm - the cycle the brain uses to alternate between focused and diffuse thinking. After two hours of deep work, attention drops sharply no matter what you do, so a longer break is the only way to come back fresh. Three cycles works too if you find four too long; six is usually too many.
