Twenty-five minutes is the classic focused work-session length, familiar to anyone who has used the Pomodoro Technique's standard work interval, though it works perfectly well on its own as a general-purpose focus block too, no named technique required. It is long enough to get properly into a task and short enough that a break always feels close.
This page loads already set to twenty-five minutes, full screen and readable from across a room. If you want the full technique with its short-break cycle built in and explained, the dedicated Pomodoro timer sets that structure up for you.
Need a different length? The full timer page has quick presets from ten seconds to ten minutes plus a custom field for anything else, and pairs well with charades cards, bingo cards and word searches if you are running a game rather than a work session.
FAQ
Is this timer free?
Yes, completely, no signup, no account and no limit on how many times you run it. Pick it and press start.
Does it keep correct time in a background tab?
Yes. The countdown is worked out from the clock rather than counted tick by tick, so a tab you switched away from comes back showing the correct time even if the browser paused it while it was hidden.
Do I have to follow the Pomodoro Technique to use this?
No, twenty-five minutes works as a plain focus timer on its own. If you want the named technique's short-break cycle, the dedicated Pomodoro timer page sets that structure up rather than just the raw length.
