The Classic 25/5 Pomodoro Timer
25 minutes on, 5 minutes off, a longer break every fourth round.
You searched for the classic setup, so here it is, ready to run. Twenty-five minutes of work, five minutes of rest, and a longer break after four rounds. Nothing to install and no account to make.
This is the exact ratio Francesco Cirillo used with a kitchen timer in the late 1980s. It stuck around because it fits most tasks most of the time. Twenty-five minutes is long enough to make real progress and short enough that starting never feels like a big deal.
Pick one task, press start, and let the timer keep the rhythm for you.

Questions
Why 25 and 5 specifically?
It is short enough that beginning feels easy and long enough to get something done. The five minute break is a real pause without letting you drift too far from the work.
Can I change the lengths?
Yes. Open settings on the timer and adjust the focus and break minutes to whatever suits you. The 25/5 values are just the starting point.
What happens after four rounds?
The timer gives you a longer break, fifteen minutes by default, then starts the cycle again. The dots under the label show where you are in the current set.
