Pomodoro Timer

What is the Pomodoro Technique?

The Pomodoro Technique breaks work into focused 25-minute intervals ("pomodoros") separated by short 5-minute breaks. After four focus sessions, you take a longer 15-minute break. This rhythm helps maintain concentration while preventing burnout over long study or work sessions.

Where the Pomodoro Technique comes from

The method was developed by Francesco Cirillo in the late 1980s, while he was a university student looking for a way to actually get studying done. He used a kitchen timer shaped like a tomato pomodoro is Italian for tomato to time 25-minute study blocks, and the name stuck even though this timer doesn't require an actual tomato.

Why the short-interval structure works

The technique's core idea is that sustained, unbroken focus is hard to maintain attention naturally drifts after 20-30 minutes on a single task, and knowing a break is coming soon makes it easier to resist checking email or your phone in the meantime. Breaking work into short, timed sessions with a hard stop also reduces the temptation to multitask, since you've committed to just one task until the timer ends. The mandatory breaks matter too: stepping away, even briefly, helps prevent the mental fatigue that builds up over a long work session.

The standard rhythm and why round 4 is different

The classic structure is four 25-minute focus sessions, each followed by a 5-minute short break, with a longer 15-30 minute break after the fourth round instead of another short one. This timer follows that pattern by default (25 / 5 / 15, with the long break triggered every 4th round) but lets you adjust all three lengths some people prefer 50-minute focus blocks with 10-minute breaks for deep work, or shorter 15-minute sprints for tasks that are hard to start.

How to use this timer

Click "Start" to begin a focus session. When the timer ends, it automatically switches to a break and plays a sound. Use "Skip" to move to the next session early, or "Reset" to start the current session over. Pick one task before starting, work on only that task until it rings, and take the break even if you feel like continuing the discipline of actually stopping is part of what makes the technique effective over a full day, not just a single session.

FAQ

Does it play a sound when time is up?
Yes a short tone plays when a session ends, so you don't need to watch the screen constantly.

Can I change the session lengths?
Yes adjust the focus, short break, and long break lengths any time; changes apply the next time that session type starts.

Who invented the Pomodoro Technique?
Francesco Cirillo, in the late 1980s, using a tomato-shaped kitchen timer which is where the name comes from (pomodoro is Italian for tomato).

Why is there a longer break every 4 rounds?
The longer break (15 minutes by default) gives you a more substantial recovery period after four consecutive focus sessions, which helps sustain concentration across a full work day rather than just a single hour.

What happens if I close the tab mid-session?
The timer stops running, since it's calculated while the page is open. Reopening the page resets the current session back to its full length it doesn't resume from where you left off.

Is 25 minutes the "right" length for everyone?
No 25 minutes is the traditional default, but the ideal focus length varies by person and task. Use the input fields to try longer sessions for deep, uninterrupted work or shorter ones for tasks you're avoiding.
