What is the Pomodoro Technique®?
It is a time-management method created by Francesco Cirillo, who began developing it in the late 1980s while at university, using a tomato-shaped kitchen timer (“pomodoro” is Italian for tomato; see pomodorotechnique.com). In short: choose a task, work on it for 25 minutes, take a short break, and after four rounds take a longer break of 20 to 30 minutes (archived guide). Short breaks are typically 5 to 10 minutes (Wikipedia). The method is the creator’s; this page only keeps time for it.
Presets: 25/5, 50/10, 15/3 or your own
| Preset | Focus | Short break | Long break |
|---|---|---|---|
| Classic 25/5 | 25 min | 5 min | 15 min after every 4th focus |
| Deep 50/10 | 50 min | 10 min | 20 min after every 3rd focus |
| Quick 15/3 | 15 min | 3 min | 10 min after every 4th focus |
Deep suits long writing or coding; Quick helps you get going. Custom opens the steppers in Settings: focus from 1 to 120 minutes and a long break after 2 to 8 sessions. Changes start with the next phase.
Plan the session with tasks
Give each task an estimate of 1 to 10 sessions. The first task becomes Working on, and every completed focus adds one to it (“1 / 2”). Pick another task with its radio button, tick finished ones, and reorder by dragging or with Alt+↑ and Alt+↓. The line below the list, such as “6 sessions left · finish ≈ 4:05 PM”, includes the breaks.
Your focus stats, stored on this device
Your focus (this device) shows today’s sessions and minutes, this week’s minutes (Monday to Sunday), your streak of days with at least one finished focus, and a 7-day chart. A skipped focus adds its minutes only after a full minute. Reset stats clears the stats; Clear my data removes everything.
Break alerts, notifications and auto-start
A chime ends each focus session and a bell ends each break, each ringing for 10 seconds by default. Auto-start breaks is on and Auto-start focus is off, so the next session waits with “Focus done — start your break” in the tab title. Notify me when a phase ends adds a desktop notification while the tab is hidden.
A study timer for fullscreen and streams
Press Fullscreen or F to use it as a pomodoro clock on a second screen: the time, phase word, dots and current task. The buttons fade after three seconds, and the screen stays awake while the timer runs where the browser allows it.
Calm looks
Look in Settings switches from Phase colors (navy focus, green breaks, indigo long breaks) to Night, High contrast, Ocean, Dusk or Forest. For a calm clock all day, try the aesthetic clock.
Study-with-me streams and videos
Share → Copy OBS link gives a browser source for OBS or Streamlabs with the time and phase word on a transparent background; add task=1 to the link to show your current task.
Options explained
Ring for (10 s by default), Focus-end sound (Chime) and Break-end sound (Bell) each have a test button. Volume is 70 % and M mutes. Keep screen on, Show time in tab title and Show progress in tab icon are on.
How this timer keeps time
When a phase starts, the timer saves the moment it should end and shows that moment minus your device clock, so a hidden tab can’t drift, and the end sound is scheduled on the audio clock in advance. It works offline after loading and uploads nothing. A phase that ended while the page was closed still counts, but the next one waits instead of inventing sessions. See how our timers stay accurate.
Tips and limits
- Closing the tab stops the alerts; a sleeping laptop can’t ring, and phones pause background pages.
- Private windows may forget your stats.
- One break without a cycle? Use the 5 minute timer. For open-ended study time, a stopwatch counts up.
FAQ
What is a Pomodoro-style timer?
It is a timer that runs a focus and break cycle: 25 minutes of focus, a 5-minute break, and a longer 15-minute break after every fourth focus session. The rhythm comes from Francesco Cirillo's Pomodoro Technique. This one adds a task list and stats that stay in your browser.
Is a pomodoro always 25 minutes?
No. 25 minutes is the classic length, but you can pick Deep 50/10 for long writing or coding blocks, Quick 15/3 to get going, or Custom for anything from 1 to 120 minutes of focus. New lengths start with the next phase, so a running session is never cut short.
Is 60/10 a good rhythm?
It is a common variation for long tasks, and you can set it with Custom: Focus 60, Short break 10. Whether it suits you depends on the work. Try it for a few days and compare your focus minutes in the stats panel with your usual rhythm.
Is this timer free, and do I need an account?
Yes, it is free, and there is no sign-up. Your settings, tasks and stats are saved in this browser only and never sent to a server. That also means they don't follow you to another device, and Clear my data in Settings removes them.
Will I hear the break alert in another tab?
Yes, while your computer is awake. The chime is booked on the audio clock when a phase starts, so it rings on time even in a background tab. Turn on Notify me when a phase ends for a desktop notification too. A sleeping computer can't ring until it wakes.
How do I use it on iPhone?
Open the page in Safari and tap Start; that tap also turns on sound. Fullscreen fills the window, because Safari can't make a page truly fullscreen. Keep Safari in front with the screen on: iPhone browser tabs can't show notifications, and a locked phone pauses web pages.
Does it play music or ticking sounds?
No. You hear two short cues and nothing else: a chime when a focus session ends and a bell when a break ends, each ringing for 10 seconds unless you change Ring for. If you like background sound, play it from your own app.
Is this timer endorsed by the Pomodoro Technique's creator?
No. Pomodoro® and Pomodoro Technique® are trademarks of their owner. This Pomodoro-style timer is independent and not affiliated with or endorsed by the trademark owner. The technique was created by Francesco Cirillo; this page is an independent tool that only keeps time for the rhythm.
