Pomodoro Timer

A Pomodoro timer with focus sessions, short and long breaks, automatic cycling, a daily goal and alerts. Customise the lengths or start from 25/5, 50/10 or 90/20.

Runs in your browser. Nothing you add is uploaded.

What the Pomodoro Timer does

The Pomodoro Technique turns a long, vague work session into short, focused sprints: 25 minutes of work, a 5-minute break, and a longer break every fourth round. The structure keeps you starting, and the breaks keep you fresh. This timer runs the whole cycle for you, rings at each change, can roll straight into the next phase, counts your sessions for the day against a goal and keeps the time in the tab title so you can see it while you work elsewhere.

How to use the Pomodoro timer

  1. Optionally type what you are working on, then press Start. The timer counts down your first focus session.
  2. Work on that one thing until the alarm rings. Do not switch tasks.
  3. Take the short break when the next phase begins. After four focus sessions you get a long break.
  4. Press Skip to move on early, or choose Focus, Short break or Long break to jump to a phase. Reset returns to the first focus session.
  5. Open Timing to choose a preset (classic 25/5, deep work 50/10, 90/20) or set your own lengths, and turn on auto-start if you want phases to follow each other.

The Pomodoro Timer runs entirely in your browser — nothing you enter is uploaded, stored, or logged.

When to use it

Studying

Break a revision day into sessions, with short breaks to move and a longer rest after a block, and watch your completed sessions build up against a goal.

Deep work and coding

Use longer blocks, such as 50/10 or 90/20, for tasks that need sustained concentration, with the screen kept awake.

Beating procrastination

Committing to just one 25-minute session lowers the barrier to starting a task you have been avoiding.

Good to know

  • Write down distractions as they come up and deal with them in the break.
  • Stand up and move away from the screen on breaks, rather than checking your phone.
  • If a session is interrupted and you cannot resume it, reset and start a fresh one.
  • Try longer focus blocks if 25 minutes feels too short to get into flow.
  • The session counter resets every day; your goal and settings stay.

Frequently asked questions

What is the Pomodoro Technique?

Work in focused 25-minute blocks separated by 5-minute breaks, and take a longer break of 15 to 30 minutes after four blocks. It was developed by Francesco Cirillo in the late 1980s and named after his tomato-shaped kitchen timer.

Can I change the 25 and 5 minutes?

Yes. Choose a preset or set any focus, short break and long break length, and how many focus sessions come before a long break. Longer blocks such as 50/10 or 90/20 suit deep work better than 25/5 for some people.

Does it keep my progress if I close the page?

Settings, the current phase and today's count are saved in your browser for a few days. If a phase ended while the page was closed, it moves on to the next when you return.

Why 25 minutes?

It was the length Francesco Cirillo found workable when he developed the method as a student in the late 1980s. There is nothing magical about it: the point is a fixed, short, single-task block. Many people prefer 50 or even 90 minutes.

What counts as a completed session?

A focus phase that runs to the end. Skipping a focus phase early does not count.

Will it alert me if I am in another app?

Keep the tab open for the sound; turn on notifications for a pop-up when a phase ends. The time also appears in the browser tab's title.
