A focus timer that stays out of your way
This free online Pomodoro timer helps you work in focused sprints and take regular breaks, using the time-management method made famous by Francesco Cirillo in the late 1980s. You pick a task, start a 25-minute focus block — a “pomodoro” — and when it ends the timer rolls you into a short break automatically. After four pomodoros you earn a longer break. That simple rhythm is what makes the technique stick: it turns an intimidating workload into a series of small, finishable rounds.
What sets this timer apart is the floating window. Press Float and the countdown pops out into a small, always-on-top pane that stays visible while you write code, read, or design in another app — so you never lose track of time, and never have to hunt for the tab. The whole thing runs in your browser with a clean glassmorphism design, dark mode, and zero sign-up. There is nothing to install and no paid account. If you want that float to live outside the browser — a native glass window that stays on top of every program — there is a free desktop app too.
Where the Pomodoro Technique came from
The method has an almost comically humble origin. In the late 1980s, a university student named Francesco Cirillo was struggling to concentrate and challenged himself to focus for just ten uninterrupted minutes. The only stopwatch he had on hand was a kitchen timer shaped like a tomato — pomodoro is simply Italian for “tomato” — and that ordinary tomato timer gave the technique both its name and its core idea. Cirillo refined the rounds to 25 minutes, added the short and long breaks, and wrote up the rules that people still follow today. The lesson buried in that story is that the tool barely matters: a tomato timer, a phone, or the timer on this page all do the same job. What matters is committing to a single block of focused time and honouring the break at the end of it.
How to use the Pomodoro Technique
- 1 Write down the one task you want to focus on — and roughly how many pomodoros you think it will take. Planning in pomodoros is a skill in itself: it forces you to break a vague project into concrete, 25-minute-sized pieces.
- 2 Start the 25-minute focus timer and work on only that task. No email, no messages, no “quick” tab switches — the whole point is one unbroken block of attention.
- 3 When the timer rings, stop and take a 5-minute break — stand up, stretch, look away from the screen. Stopping on time matters as much as starting; the break is what keeps the next pomodoro sharp.
- 4 After four focus sessions, take a longer 15–30 minute break to recharge, then start the cycle over.
Two rules make the difference between a timer you ignore and a technique that actually works. First, handling interruptions: when someone breaks your focus, Cirillo’s advice is to inform, negotiate, and call back — tell them you are mid-pomodoro, agree on a later time, and write the request down to deal with in your break. Most interruptions can wait 15 minutes. Second, what counts as a completed pomodoro: a pomodoro only counts if you worked the whole block on the one task. Cut it short to check a message and it does not count — you start fresh. That strictness is the feature, not a bug: it is what turns the running tally on this timer into an honest record of focused time rather than time spent “sort of working.”
Prefer longer stretches? Switch to the 50/10 preset for deep work, the 90/20 ultradian rhythm, or the gentle 15/3 blocks that many people with ADHD find easier to start. You can also set fully custom focus and break lengths.
Why 25 minutes works
There is nothing magical about the number 25 — but the shape of a short, timed sprint lines up well with how attention actually behaves. Focus is a limited resource that drains over time, so a block short enough to hold your full attention, followed by a real rest, tends to produce better work than grinding for hours. A hard deadline also fights Parkinson’s law — the tendency for work to expand to fill the time available. Give a task an open-ended afternoon and it will happily consume the whole afternoon; give it a 25-minute box and you find the essential version of it. Committing to “just 25 minutes” is also far easier than committing to a vague, open-ended task, which is why the technique is so effective against procrastination: the barrier to starting is what it lowers most. The enforced breaks, meanwhile, are not wasted time — stepping away lets attention recover so the next block starts fresh instead of fatigued. Treat the specifics as guidance rather than gospel: if 25 minutes feels wrong for you, a shorter or longer block that you will actually stick to beats a “correct” one you keep abandoning.
When the Pomodoro Technique doesn’t work
Being honest about its limits is part of using it well. The technique is a poor fit for deep-flow work — the kind of programming, writing, or design where it takes 20 minutes just to load the problem into your head. Interrupting that with a break every 25 minutes can do more harm than good; for those sessions, reach for a longer block — the 90/20 preset above matches a full ultradian focus cycle, and 50/10 suits work that needs a warm-up before it flows. It also struggles on meeting-heavy days, where your calendar, not you, owns the clock and there are no clean 25-minute gaps to protect. And for many people with ADHD, the standard 25/5 rhythm is either too long to sustain or too rigid to start — a gentler, more flexible adaptation usually works better, which is why we keep a dedicated Pomodoro guide for ADHD. None of this makes the technique bad; it just means a good Pomodoro timer is one tool among several, best used when the work suits it. Whether you are studying, writing, coding, or clearing a backlog, that simple loop of focus-and-break is still one of the easiest productivity upgrades you can make.
