25 Minute Timer
Twenty-five minutes is the classic Pomodoro interval: long enough to make real progress on a task, short enough that starting does not feel like a big commitment. This timer is already set to 25:00 — press “Start” and go.
New to the Pomodoro Technique? The rest of this page covers what it is and how to run a full session using the timer above.

What the Pomodoro Technique actually is
The Pomodoro Technique is a time-management method built around working in short, fixed sprints instead of open-ended stretches. Each sprint — a “pomodoro,” named after the tomato-shaped kitchen timer its creator, Francesco Cirillo, originally used — is traditionally 25 minutes of focused work on a single task, followed by a short break.
The point of the fixed length is not magic in the number 25 itself; it is that a short, clearly bounded sprint is easy to commit to even when a task feels big or unappealing, and having a visible countdown running gives you a concrete reason not to check your phone until it ends.
Running a full session with this timer
Pick one task before you start — the technique works best when the 25 minutes has a single clear target, not a to-do list. Press “Start” and work until the timer hits zero and the alert sounds.
When it ends, stop — even mid-sentence — and take a short break, typically about 5 minutes. To time it, change the minutes field above to 5 and press “Start” again, then set it back to 25 for the next pomodoro. After roughly four pomodoros, take a longer break of 15 to 30 minutes before starting the cycle again.
When 25 minutes is (and is not) the right length
25 minutes suits tasks that need sustained attention but can tolerate a natural pause: writing, studying, code review, inbox cleanup. For work that is hard to interrupt mid-flow — deep debugging, a long creative session — a longer block with a longer break afterward can suit better.
If 25 minutes ends up feeling too short or too long once you have tried it a few times, there is nothing special about the number — adjust it up or down until the rhythm fits the kind of work you are actually doing.
