A Pomodoro timer that plans the session, not just the minutes
Most Pomodoro timers count to twenty-five and stop there. This one asks what you are working on, how many blocks you think it will take, and then keeps score — so you find out how long your work actually takes rather than guessing forever. It works the same whether you are revising or at your job.
Estimate in blocks, then find out how wrong you were
Add a task and say how many blocks you think it needs. Each completed block fills a dot against that estimate, and blocks under ten minutes do not count, so a false start never eats an allowance.
After three finished tasks it tells you the truth: whether you consistently underestimate, by roughly how much, and what to do about it. Almost nobody knows how long their own work takes, and this is the only way to learn it.
Plan what happens inside each block
Open a task and write a line for each block — read the chapter and mark what I do not follow, work problems one to eight, write up what I got wrong. That line then shows under the dial while the timer runs.
It means you sit down to a specific instruction you chose while thinking clearly, rather than a vague intention twenty minutes in.
Sound that is generated, not streamed
Seven soundscapes — brown, pink and white noise, rain on glass, slow surf, room tone and a deep hum — plus eight pieces of music, all synthesised in your browser as you listen. Nothing streams, nothing buffers, and there is no loop point for your ear to find and start waiting for.
The music is composed as it plays from a scale and a chord progression, so a two-hour session never repeats a bar. It also means no licensing, which is why it is free.
It tells you when the block ends
The whole point of a focus timer is that you stop looking at it. So the tab title alternates, the favicon becomes a badge, and if you allow it you get a real notification saying how long you worked and on what.
There is a zen mode too: the dial fullscreen with everything else stripped away, and the controls fading out after a few still seconds.
Common questions
Is it free?
Yes. The timer, all the soundscapes, the music, the task planner and the session history are free and always will be. Only the parts that call an AI model cost credits.
Do I need an account?
Yes — an email and a password, about twenty seconds. It is what lets your tasks and session history survive a cleared browser or a new laptop.
Does the timer keep running if I change tab?
Yes. It tracks real elapsed time rather than counting frames, so switching tabs, minimising or locking your phone does not slow it down.
Is it only for students?
No. You choose studying or work when you sign up. The timer, calendar and goals are identical either way; what changes is what sits around them — flashcards and practice papers, or projects, meetings and a workload check.
Can I change the length?
Drag the ring to set it, or use the steppers. Focus, short break and long break lengths are all adjustable, along with how many rounds before a long break.
