About the Pomodoro Timer
Work for 25 focused minutes, take a 5-minute break, and after four rounds take a longer 15-30 minute break. This timer switches to the right next mode and length automatically — just press Start again. No sign-up.
Francesco Cirillo devised the Pomodoro Technique in the late 1980s, naming it after the tomato-shaped kitchen timer he used at university: 25-minute focus blocks, five-minute breaks, and a 15-minute break after every fourth block. This timer tracks the cycle — when a session ends it sets up the next mode and length, so you only press Start. Your last 30 days of completed sessions are logged so you can see how the week went.

When the Pomodoro Timer helps
- Long study sessions where you drift to your phone after twenty minutes.
- Knowledge work that gets interrupted constantly — coding, writing, research.
- Solo creative work — drawing, music practice, language drills.
- Pair programming or study buddies — both partners work the same cycle.
- Starting a task you've put off — 'just one Pomodoro' is easier to commit to than 'a whole afternoon'.
How to use the Pomodoro Timer
- Tap Focus to confirm a 25-minute work block, then press Start.
- Work without distraction — no email, chat or quick browsing.
- When the bell rings, the timer switches to a five-minute Short break. Stand up and stretch.
- After the fourth focus block it switches to a 15-minute Long break instead.
- Change the focus and break lengths below the timer if 25/5/15 doesn't suit you.
Tips for a better Pomodoro
- Keep a notebook by the keyboard; jot down distractions during a focus block and deal with them on the break.
- Pick one specific outcome for each Pomodoro before you start. "Write the intro paragraph" beats "work on the essay".
- Don't skip breaks — they are what makes the technique sustainable.
- If 25 minutes is too short for deep work, try 50/10 by changing the focus value.
- Check the 30-day stats panel to see when in the day you focus best.
Pomodoro Timer FAQ
Why 25 minutes? Where does the number come from?
Cirillo found 25 minutes long enough for real progress and short enough to stay focused, and 25 + 5 fits neatly into a half-hour calendar slot.
Should I take a break if I am in flow?
Usually yes — the rhythm is what trains focus. If you cannot stop, finish the thought and use the break to note where you were.
How many Pomodoros should I aim for in a day?
6-8 is a strong day for most knowledge workers. Consistency matters more than the occasional huge day.
Can I customize the lengths?
Yes — change the Focus, Short break and Long break minute fields at any time. Your preferences are saved per device.
Does ClockAura log my Pomodoros?
Yes — each completed session is recorded against an anonymous ID, showing your last 30 days of focus minutes and breaks. No account needed.
Can I use this as a study timer?
Yes — it is one of the most popular study timers. Each session is a 25 minute focus block followed by a short break, which is easy to repeat for a whole revision day. Many students run it on a second screen for "study with me" style sessions.
Why is it called a tomato timer?
Pomodoro is Italian for tomato. Francesco Cirillo, who created the technique, used a tomato-shaped kitchen timer, so people still call it the tomato timer. This pomodoro online version works exactly the same way without the ticking.
