Work in one focused stretch, then take a real break. The standard rhythm is 25 minutes of focus, a 5 minute break, and a longer 15 minute break after four sessions.
A fixed end makes starting easier, and the break is what keeps attention sharp across a full day.
A time management method that breaks work into short, timed intervals separated by real breaks. Each interval is a Pomodoro. Instead of committing to an open-ended task, you commit to one fixed, short stretch of it, which is easier to start and easier to sustain.
Francesco Cirillo developed it in the late 1980s as a university student, naming it after the tomato-shaped kitchen timer he used to time his study sessions. Pomodoro is Italian for tomato.
Two things do the work. Committing to a short, fixed interval is easier than committing to a task of unknown length, which is why timeboxing cuts procrastination. And attention measurably degrades over long uninterrupted stretches, while short, deliberate pauses restore it.
Four sessions make one round: 25 minutes of focus, a 5 minute break, three more times, with the fourth followed by a longer break instead of a short one. Cirillo's own guidance allows 15 to 30 minutes for that longer break; this app defaults to 15.
50/10 keeps the same 5 to 1 ratio of work to break, doubled: 50 minutes of focus, a 10 minute break. It isn't part of Cirillo's original technique. It grew up alongside it, favored for complex or highly immersive work, where 25 minutes often ends just as concentration arrives. There's no standard long break for it; this app uses 30 minutes, the same 3 to 1 ratio the classic rhythm uses for its own.
The rhythm above is a starting point rather than a rule. Some work does better at 50 minutes, some days only support 15. What holds constant is the structure: one task, a defined end, and a real break, ideally away from the screen, which restores more than a break spent scrolling.
50/10 has no single point of origin. It grew informally, through productivity blogs and timer apps rather than any one source, tracking the broader shift toward protecting longer, uninterrupted blocks of focus for complex work over shorter, more frequent ones.
One focus timer, two breaks, and three quick timers. Breaks don't start on their own. Completions are tallied in dots.
Name what you're working on before you start and it lands in your history for that session. Add a chip to group many different sessions into one long-term total. Quick timers keep no record. Resets leave none either.
Everything is stored in this browser. No account, no tracking, completely private. Clearing your browser data clears the app, so export from the sidebar if you'd like to keep your records.
Focus, short break, and long break durations are all adjustable in Settings, with a one-click preset for the 50/10 technique alongside the classic 25/5/15. Three additional quick timers handle anything that isn't a Pomodoro at all: a kettle, a load of laundry, a phone call.
Every completed focus and break session becomes a colored dot in the day's row and a full entry in the history sidebar, with its intention, chip, duration, and time. The sidebar also totals the current week and every chip's running total, so a chip can track one ongoing project across weeks or months of sessions.
Records export to JSON or CSV at any time, and a JSON export can be imported back in, which also makes moving data between browsers or devices possible without an account. The app installs as a standalone web app and keeps working offline once loaded, since nothing it does depends on a network connection.
Optional browser notifications and a completion sound mark the end of every session. The fourth focus session of the day gets a different notification than the rest, since it's the one that calls for the longer break. The browser tab shows a live countdown in its title and a progress ring on its icon while a timer runs.
