25/5 Pomodoro Timer — free, with music
This is the original Pomodoro split: 25 minutes on one task, 5 minutes off. Francesco Cirillo timed it with a kitchen timer in the late 1980s and the ratio has survived because it works — 25 minutes is short enough that starting doesn't feel like a commitment, and long enough to actually finish something small.
Use 25/5 when the work is made of small, nameable pieces: replying to a queue, fixing a list of bugs, grinding flashcards, editing a document section by section. If you keep hitting the break mid-thought, your tasks probably need a longer block — try 50/10 or 90/15 instead.
The timer above runs right here, no account needed. Press start, work the block, take the break when it flips. That's the whole method.
Questions
Is this 25/5 timer free?
Yes. The timer on this page runs in your browser with no account and no ads. The full Flow app also has a free tier — the paid plan adds the full music library and extra ambient sounds.
Does the timer keep running if I switch tabs?
Yes. The countdown keeps going in the background and the remaining time shows in the tab title, so you can work in another window.
What is the 25/5 method?
You work in fixed blocks: 25 minutes on a single task, then a 5-minute break, then repeat. The fixed end point makes it easier to start, and the break keeps the next block usable.
Where is the music?
This page is the bare timer. The Flow app pairs the same presets with original focus music produced in-house by Virzy Guns — not stock loops — plus an ambient mixer for rain, café, and similar layers.
