Twenty-five minutes is the focus block that Francesco Cirillo named after his tomato-shaped kitchen timer in the late 1980s. The idea is that twenty-five minutes is the longest interval most people can sustain undivided attention, and the firm endpoint protects you from drifting. One Pomodoro, one task, no exceptions — and a five-minute break afterwards before the next one starts. This page replaces the kitchen timer. The 25 minute countdown runs server-side, so closing the tab does not abort it. Pick a notification channel before you start and the ping reaches you the second the block ends — Telegram message, browser push, or email. Label the timer with the task you are sitting down to ("draft outline", "essay paragraph 3", "debug auth flow") and the notification will include that label, which makes the next-action handoff instant. Four Pomodoros is the textbook morning. After the fourth, take a longer 15–30 minute break instead of the usual 5. Use the 5 minute timer for those short breaks; jump to 30 minutes if you need a slightly longer block; or use the hub to set up a recurring focus reminder every weekday.

FAQ

Why 25 minutes for a Pomodoro?
Cirillo found that 25 minutes is long enough for meaningful progress on a task and short enough that almost anyone can resist distraction for the full block. After four Pomodoros, take a longer break.
Should I really stop at 25 minutes if I am in the flow?
Cirillo says yes — the discipline of stopping is what makes the system work, and the 5 minute break is what lets you sustain six or eight Pomodoros across a working day. If you need to keep going, treat the next block as a fresh Pomodoro.
Does the timer survive a closed tab?
Yes. The 25 minute countdown runs on the server. Close the tab, lock your laptop, switch devices — the notification still arrives on the channel you picked.
Can I save this as a recurring focus block?
Yes. After running it once you can save the timer as a daily or weekday-only reminder so the 25 minute block is queued up automatically.
