      A Pomodoro timer that runs the whole cycle for you

      This Pomodoro timer switches between 25 minutes of focus and 5-minute breaks on its own, then gives you a 15-minute long break after every fourth session. The phase name, its colour, the session number and four cycle dots always show where you are. Use it as a study timer or a focus timer for work. Everything runs in your browser with no account: your settings, tasks and stats stay on your device.

      The Pomodoro technique in a nutshell

      The method was developed in the late 1980s and takes its name from a tomato-shaped kitchen timer (pomodoro is Italian for tomato). It comes down to four rules:

      1. Pick one task.
      2. Work on it for 25 minutes without interruption: no messages, no phone, no other tabs.
      3. Take a 5-minute break: stand up, get some water, look out of the window.
      4. After 4 sessions, take a longer break of 15 to 30 minutes.

      With the default settings, one full cycle lasts 4 × 25 + 3 × 5 + 15 = 130 minutes, or 2 hours 10 minutes, of which 100 minutes are focus time.

      Why it can help

      It does not suit everyone, but many people find three things useful. It breaks work into chunks: "revise biology" feels endless, while "one session on photosynthesis" is easy to start. It keeps distractions at bay, because everything else can wait until the break. And it builds in regular rest, which is easy to skip when you are busy.

      How to use this timer

      1. Type what you are working on in "Current task" and click "Add". The selected task gets a tomato every time a focus session finishes.
      2. Click "Start" or press the space bar. The countdown starts at 25:00 and the time left also appears in the browser tab title.
      3. "Pause" stops the clock, "Resume" picks up where you left off. "Skip phase" jumps to the next phase, and "Reset" takes you back to session #1.
      4. A soft sound plays at the end of each phase. If "Start the next phase automatically" is unticked, the timer shows the next phase and waits for your click.
      5. "Full screen" makes the countdown huge, handy on a second monitor or a tablet on your desk.

      "Browser notification" alerts you when the tab is hidden; your browser only asks for permission when you tick the box. "Keep the screen on" stops the screen from going to sleep while the timer runs, if your device supports it.

      The "Today" panel counts completed sessions and focus time: after four 25-minute sessions it shows 4 and 1 hr 40 min. The counters reset at midnight, and small bars show the last 7 days.

      Changing the lengths

      Each length can be set from 1 to 90 minutes. For a dissertation or deep coding work, many people prefer 50 minutes on and 10 off: four sessions then add up to 200 minutes of focus. For a child doing homework, 15 minutes of work and a 5-minute break often works better. A new length applies straight away if the phase has not started yet, otherwise from the next phase.

      Ways to use it

      • Exam revision: one session per topic for GCSEs, A levels or finals, with breaks spent away from screens.
      • Homework: two short sessions after school, then stop.
      • Working from home: deal with email in one dedicated session instead of all day long.
      • Writing: set a simple target, such as 300 words per session.
      • Decluttering: 25 minutes for one cupboard, and stop even if it is not finished.

      Handling interruptions

      An idea pops up, or you remember something to buy? Jot it down on paper and go straight back to your task; you can deal with it during the break. If someone really needs you, click "Pause". If the session is lost, "Skip phase" lets you start fresh: a skipped phase does not count as a completed session and earns no tomato.

      Frequently asked questions

      Does the timer stay accurate in a background tab?

      Yes. The time left is worked out from the phase's end time, not counted second by second. If you reload the page, the phase and time left come back. On a phone that goes to sleep, the sound may not play.

      Why am I not getting notifications?

      They are off by default. Tick "Browser notification" and accept the prompt. If you blocked it, allow notifications for this site in your browser settings.

      Are my stats sent anywhere?

      No. They stay in this browser on this device. "Clear statistics" deletes them.

      How is this different from the 25 minute timer?

      The 25 minute timer runs a single countdown. This Pomodoro timer chains focus sessions and breaks, counts sessions, triggers the long break every 4 sessions and keeps your daily stats.
