About Zeno

Zeno started as a single tool — a chess clock built for two players sharing one screen — and grew into a small set of timers that share the same design and the same principle: open the page, get a working timer immediately, and never be asked to sign up, install anything, or look at an ad to do it.

Every timer on this site runs entirely in your browser. Settings you set once, like your preferred Pomodoro lengths or your chess clock's time control, are remembered locally on your device for next time. Nothing is uploaded, tracked, or sold — the tools work the same whether it's your first visit or your hundredth.

If you're looking for something more specific than the general-purpose version of a tool, the pre-set links above jump straight to a version tuned for a particular use — blitz chess, exam-day countdowns, ADHD-friendly focus sessions, and more — each with its own defaults and guidance so you don't have to reconfigure it yourself.
