Pomodoro Timer
Twenty-five minutes of work, then a break you actually take
Focus
Focus rounds finished: 0
Custom lengths (minutes)
Set a focus block, run it, and let the timer tell you when to stop — a chime sounds at the end of every round and the countdown shows in your browser tab, so it keeps working while you are in another window. Focus, short break and long break lengths are all adjustable, and finished rounds are counted for the session.

Frequently asked questions
Is Pomodoro Timer free to use?
Yes. Every tool on ZeroGPT is free, with no account, no trial period and no credit card. There is nothing to unlock.
Is my text or file uploaded anywhere?
No. Pomodoro Timer runs entirely in your browser using JavaScript. Your content is read from the page, processed on your device, and discarded when you close the tab.
How accurate is it?
It is a strong signal, not a verdict. Pomodoro Timer measures statistical patterns, and patterns can be wrong in both directions. Use the result as one input into your own judgement, especially when the stakes are high.
Does it work on my phone?
Yes. The layout adapts to small screens and the tools are built to work with touch. Very large files may be slower on an older phone.
Which languages are supported?
ZeroGPT is available in English, French, German, Spanish, Italian and Portuguese. The text tools work best on English but handle other Latin-script languages reasonably well.
