Pomodoro Timer

How Pomodoro Timer works

A 25-minute focus timer with breaks and session counting. Work in focused blocks with automatic breaks; a short beep marks each phase change. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

Work, rest, repeat

Set a work length (25 minutes by default, adjustable 1–90) and a rest length (5 minutes, 1–30), and the timer alternates between them. The point is not the specific numbers but the rhythm: short focused blocks with enforced breaks.

The classic 25/5 comes from the technique's origin; 50/10 suits work that needs a longer warm-up, and 90/20 matches a natural ultradian cycle.

Why the break is not optional

Skipping breaks is the most common way to make the technique useless — the value comes from sustained focus across a day, not from one long block. A five-minute break away from the screen resets attention far better than five minutes of scrolling.

Four cycles then a longer rest is the usual pattern.

Running it

The timer runs in the page, so the tab must stay open. It is deliberately simple: no accounts, no statistics, no streak to maintain — which is also why it does not nag you when you ignore it.

Good to know

• Works offline once loaded, including on flights and in locked-down networks.
• No file size limit beyond your device's own memory.
• Free to use, with no account and no usage counter.
• Results are produced locally, so they are not logged or shared with anyone.
