A Pomodoro timer that stays accurate when you look away
Built for students and remote workers across Canada, this timer fixes the flaw most online timers share: they count ticks with a simple interval loop, so when the browser throttles a background tab, they silently fall behind by minutes. It anchors every session to a real timestamp and recalculates the remaining time on each tick, so switching tabs, locking your laptop, or presenting in another window never costs you a second. Everything runs in your browser: tasks, stats, and the timer itself work with the internet switched off, and nothing you type is sent anywhere.
What is the Pomodoro Technique?
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. You work in focused intervals, traditionally 25 minutes, called pomodoros, separated by short breaks of about 5 minutes. After four pomodoros you take a longer break of 15 to 30 minutes. The name comes from the tomato-shaped kitchen timer Cirillo used as a university student; pomodoro is Italian for tomato.
The method, its rules, and its history are documented in Cirillo's book The Pomodoro Technique.
How to use the Pomodoro Technique
The method has six steps. The discipline is in treating the pomodoro as indivisible: once started, it either completes or does not count.
Choose one task
Pick a single task and add it to the task list above with an estimate of how many pomodoros it will take. Estimating is half the skill; comparing estimates to reality trains your planning over time.
Set the timer to 25 minutes
Start the timer. The classic interval is 25 minutes, but the presets above offer longer ratios if your work rewards deeper immersion.
Work until the timer rings
Work on that one task only. If a distraction surfaces, jot it down on paper or in a task entry and return to the work. If something truly urgent interrupts, abandon the pomodoro and start fresh later; a pomodoro cannot be paused into halves and still count.
Mark the pomodoro complete
When the timer rings, the session logs automatically here. One full, undisturbed interval is the unit of progress, not the number of items crossed off.
Take a short break
Step away for about 5 minutes. Stand up, stretch, get water. Avoid feeds and inboxes; the break is for your attention to recover, not to be re-captured.
After four pomodoros, take a long break
Take 15 to 30 minutes after every fourth pomodoro. The cycle dots under the dial track your position in the cycle automatically.
Pomodoro intervals compared: 25/5 vs 50/10 vs 52/17 vs 90/20
The 25-minute pomodoro is a convention, not a law. Different ratios suit different kinds of work, and all four below are available as one-click presets in the timer. The chart shows how each ratio structures the same 3-hour block; the totals are pure arithmetic.
| Preset | Work / break | Origin | Best suited for | Watch out for |
|---|---|---|---|---|
| Classic Pomodoro | 25 / 5 | Francesco Cirillo's original method from the late 1980s | Studying, email, admin, tasks you procrastinate on, building the habit | Interrupts deep states; some people find 25 minutes ends just as they get going |
| Extended | 50 / 10 | Common doubling of the classic ratio, popular with study-with-me communities | Reading, writing drafts, problem sets, longer meetings between blocks | Harder to start than 25 minutes when motivation is low |
| 52 / 17 rule | 52 / 17 | Reported by DeskTime in 2014 as the average rhythm of its most productive users | Office-style knowledge work with generous real breaks | It is an observed correlation from one product's data, not a controlled experiment |
| Deep work | 90 / 20 | Aligned with the roughly 90-minute ultradian rest-activity cycle described by sleep researcher Nathaniel Kleitman | Programming, design, mathematics, anything with heavy context to load | Demanding; most people manage only two or three true 90-minute blocks a day |
The science behind timed focus sessions
The Pomodoro Technique was invented from practice, not theory, but several well-studied effects explain why structured intervals help.
Unfinished switches tax the next task
Research by Sophie Leroy found that when people switch tasks, part of their attention stays with the previous task, degrading performance on the next one. A pomodoro counters this by making single-tasking the explicit rule and by giving stray thoughts a place to go: write them down, return to the work.
Alertness moves in cycles
Nathaniel Kleitman described a basic rest-activity cycle of roughly 90 minutes that continues during waking hours. Timed breaks work with this wave instead of against it, which is the rationale behind the 90/20 preset for deep work.
Small commitments beat big intentions
The hardest moment of most work is the first one. Committing to a single 25-minute interval is a far smaller psychological ask than committing to finish the task, which is why the technique is so often recommended against procrastination.
Pomodoros make planning measurable
Estimating tasks in pomodoros, then comparing the estimate to the count it actually took, gives fast feedback on your planning accuracy. Over weeks this calibrates your sense of how long work really takes, which no calendar can teach.
Anatomy of a Pomodoro cycle
One full cycle is four focus intervals, three short breaks, and one long break. Inside each interval, the first minutes settle you into the task and the final minutes are for a quick recap of where to resume.
What most online Pomodoro timers are missing
We reviewed the typical feature set of popular free Pomodoro timer sites before building this one. The pattern: a start button, fixed intervals, and not much else without creating an account.
| Capability | Typical online timer | This timer |
|---|---|---|
| Accurate in background tabs | Often drifts; interval counting is throttled | Yes, timestamp-anchored, recalculated every tick |
| Task list with pomodoro estimates | Usually behind a signup | Yes, free, on the same screen |
| Session stats without an account | Rare | Pomodoros, focus minutes, tasks done, daily goal |
| Research-grounded interval presets | Single fixed 25/5 | 25/5, 50/10, 52/17, 90/20 with provenance |
| Custom durations and long-break interval | Sometimes | All four values adjustable |
| Auto-start controls for breaks and focus | Sometimes | Independent toggles |
| Sound choice, volume, optional ticking | Single fixed beep | Three synthesized sounds plus tick, no audio files |
| Desktop notifications | Sometimes | Yes, permission asked only when enabled |
| Countdown in the tab title | Sometimes | Yes |
| Keyboard shortcuts | Rare | Space, R, S, Z |
| Zen full-screen mode | Rare | Yes, one key |
| Works offline | Sometimes | Single self-contained page |
Pomodoro timer for studying, work, coding, and ADHD
Students and exam prep
The classic 25/5 rhythm suits reading, flashcards, and problem sets, whether the library is at UBC, Waterloo, U of T, or McGill, and the task list doubles as a study plan: list topics, estimate pomodoros per topic, and watch estimates improve week over week. The long break is a natural point to switch subjects.
Remote and office work
Timeboxing email and admin into dedicated pomodoros stops them from leaking across the whole day. The 52/17 preset matches an office rhythm where breaks are real breaks: walking, coffee, a conversation, rather than a feed scroll at the desk.
Developers, designers, writers
Work with heavy mental context punishes interruption, because rebuilding state is expensive. The 90/20 preset protects longer immersion, and the recap habit at the end of each interval, noting exactly where to resume, makes the next start cheap.
ADHD and focus difficulties
Many people with ADHD report that externalized time, a visible countdown rather than an internal sense of duration, makes starting easier and hyperfocus less costly to exit. Short intervals lower the activation barrier; the bell gives permission to stop. This is a widely reported pattern and a reason clinicians often suggest timer-based methods, not a treatment claim.
A Pomodoro timer built around Canadian routines
Focus works the same everywhere, but schedules do not. This site is built for how Canadians actually study and work.
December and April crunch
Canadian universities concentrate final exams in December and April. The task list doubles as an exam plan: enter each course or topic, estimate pomodoros, and the goal dots turn a vague study week into a countable one. The 50/10 preset suits long library blocks; switch to 25/5 when motivation dips.
From Pacific to Newfoundland
Canada spans six time zones, including Newfoundland's unusual half-hour offset. None of that matters to a pomodoro: the timer measures duration, not clock time, so it behaves identically in Vancouver, Winnipeg, Toronto, Halifax, and St. John's, and it keeps running offline on a flight or a train with no signal.
Remote work across 4.5 hours
A team spread from Vancouver to St. John's spans four and a half hours of clock difference, which shrinks the shared meeting window and raises the value of protected solo focus. Pomodoro blocks pair naturally with async work: focus during your own hours, surface updates at the overlap.
Long nights, structured focus
Canadian winters mean early darkness and long indoor evenings, which can blur into unstructured screen time. A visible countdown carves the evening into deliberate focus and genuine rest, and the bell gives you a clean stopping point instead of an endless scroll.
Six Pomodoro mistakes that make it fail
Spending breaks on feeds
Five minutes of social media is not rest; it is a different demand on the same attention, and it routinely overruns the break.
Stand up, move, look out a window. Keep breaks physical and screen-free.Treating the timer as a suggestion
Pausing mid-pomodoro to check one thing dissolves the entire structure. The interval only protects you if it is indivisible.
Write the distraction down and handle it after the bell. If truly urgent, abandon the pomodoro and restart cleanly.Multitasking inside an interval
Running two tasks in one pomodoro reintroduces the switching cost the method exists to remove.
One pomodoro, one task. Split mixed work into separate entries on the task list.Skipping the long break
Chaining six or eight intervals back to back feels productive and quietly degrades the later ones.
Honour the long break after every fourth pomodoro; the cycle dots exist to make it visible.Never estimating
Using the timer without estimates discards half the method: the feedback loop that improves your planning.
Estimate pomodoros per task before starting, then compare with the actual count.Forcing one ratio on every kind of work
25 minutes can be too short for deep technical work and too long for grinding admin, and abandoning the method entirely is the usual result.
Change the ratio, not the method. Try the presets and keep what your work responds to.Pomodoro and focus terms, defined
- Pomodoro
- One indivisible focus interval, traditionally 25 minutes, named after the tomato-shaped kitchen timer Francesco Cirillo used. Also the unit for estimating tasks.
- Long break
- A 15 to 30 minute break taken after every fourth pomodoro, closing one full cycle.
- Timeboxing
- Allocating a fixed time period to an activity and stopping when it ends, regardless of completion. The Pomodoro Technique is timeboxing with a fixed box size and mandatory rest.
- Attention residue
- The portion of attention that remains on a previous task after switching, described in research by Sophie Leroy. It degrades performance on the task you switched to.
- Ultradian rhythm
- A biological cycle shorter than a day. The roughly 90-minute basic rest-activity cycle described by Nathaniel Kleitman is the one most cited in discussions of focus and is the basis of the 90/20 preset.
- Deep work
- Cal Newport's term for cognitively demanding, distraction-free work that creates new value and is hard to replicate. Longer intervals such as 90/20 are designed for it.
- Context switching
- Moving between tasks or projects, which carries a cost in time and accuracy while the mind reloads the new context. Single-task intervals exist to minimize it.
- Flowtime
- A variation that drops fixed intervals: you note your start time, work until focus naturally fades, then take a break proportional to the session. Useful for people who find the bell disruptive in flow.
