Work until the bell — stay focused on one task until the timer reaches zero. A notification sound plays when time is up.
3
Take a short break — after each pomodoro, take a 5-minute break. After 4 pomodoros, take a longer 15-minute break.
4
Track tasks — switch to the Tasks tab to add what you're working on. Completed pomodoros are counted against each task.
5
Customise intervals — go to Settings to change focus duration, break lengths, and notification preferences.

Frequently Asked Questions

What is the Pomodoro Technique? ▾
The Pomodoro Technique is a time management method developed by Francesco Cirillo. It works in cycles: 25 minutes of focused work (one "pomodoro"), followed by a 5-minute break. After 4 pomodoros, you take a longer 15–30 minute break. This pattern improves mental agility and prevents fatigue.
Can I change the timer duration? ▾
Yes — go to the Settings tab. You can set any focus duration (1–120 minutes), short break length, long break length, and how many pomodoros trigger a long break. Click Save Settings to apply your changes immediately.
Will the timer work if I switch browser tabs? ▾
Yes. The timer uses JavaScript's setTimeout/setInterval which continues running in background tabs. However, some browsers may throttle background tabs — for best results keep the timer tab active or visible. The page title also updates with the countdown so you can see it from any tab.

Running the Pomodoro Technique With a Simple Online Timer

The appeal of the Pomodoro Technique isn't really about the number 25 — it's that committing to a short, fixed block of focused work feels far more achievable than committing to an open-ended "work until it's done" session. A Pomodoro timer makes that commitment concrete: a visible countdown, a clear stopping point, and a built-in break on the other side of it.

The Structure Behind the Technique

The method, developed by Francesco Cirillo in the late 1980s, follows a simple cycle: 25 minutes of focused work, called a pomodoro, followed by a 5-minute break. After completing a set number of pomodoros — 4 by default — a longer break of 15 minutes follows before the cycle starts again. All of these durations, along with how many pomodoros trigger the long break, can be adjusted in the settings if the default 25/5/15 split doesn't fit your work rhythm.

What the Tomato Row Actually Shows

The row of tomato icons beneath the timer fills in as you complete pomodoros within your current cycle, resetting once a long break is triggered. It's a quick visual gauge of how close you are to your next longer break, at a glance, without needing to do the arithmetic of "how many have I done since the last long one" yourself.

Using the Task List Alongside the Timer

The Tasks tab lets you keep a simple list of what you're working on, each with a checkbox to mark it done. It's worth being clear that this list runs independently of the timer itself — checking a task off is a manual action you take when you finish it, rather than something the timer automatically updates as pomodoros complete. Think of it as a lightweight to-do list you keep open next to your focus sessions, not an automatic time-tracking log per task.

Why Structured Breaks Matter as Much as the Focus Blocks

It's tempting to treat the break as optional once you're in a flow, but the break is part of what makes the technique sustainable over a full day rather than just a single burst of focus. Skipping breaks repeatedly tends to erode the same concentration the technique is meant to protect — the short breaks exist specifically to prevent the kind of fatigue that makes a fourth or fifth pomodoro much harder to sustain than the first.

Frequently Asked Questions

Does the timer keep running if I switch to another browser tab?

The timer continues to run using your browser's own timing functions, so it should keep counting in the background. Some browsers do throttle inactive tabs to save resources, which can occasionally cause a very slight delay — the page title also updates with the live countdown, so you can check progress from another tab without switching back.

Does completing a pomodoro automatically add to a task's count?

No — the task list and the timer run independently. Tasks are a simple checklist you check off yourself; completed pomodoros aren't automatically linked to a specific task in the list.

Can I change the 25-minute default to something longer or shorter?

Yes — the Settings tab lets you set any focus duration, short break length, long break length, and how many pomodoros trigger a long break. The classic 25/5/15 split is a starting point, not a fixed rule.

Are my settings and stats saved if I close the tab?

Yes — your interval settings and task list are stored in your browser and will still be there the next time you open the page on the same browser and device, though they won't automatically carry over to a different device.

Related Tools and Resources

A few related tools suit slightly different focus styles than the fixed Pomodoro structure.

Use a Focus Timer for a single uninterrupted deep-work block without the built-in break cycle.

Try a Study Time Tracker if you want an open-ended stopwatch and a subject-by-subject log instead of fixed intervals.

A Daily Habit Tracker is useful for building a consistent daily focus routine over time, beyond a single session.

Use a Countdown Timer if you just need a plain single countdown without the Pomodoro cycle structure.

A Small Commitment That's Easy to Actually Start

The real value of the Pomodoro Technique isn't the specific numbers — it's that a 25-minute block feels small enough to start without much resistance, and the built-in break makes the next one feel achievable too. The timer's job is just to hold that structure so you don't have to think about it.
