About Click Test Pro

Click Test Pro is a set of free mouse and keyboard tests: a clicks-per-second test, a click counter, a spacebar counter, tests for faulty mouse switches and scroll wheels, and tests for the common fast-clicking techniques. Every test runs in your browser. There are no accounts and no downloads.

How the timing works

All the tests share one timing engine. It listens for pointer and key events and records each one's own timestamp, the moment the browser received the input, rather than the time the page got round to handling it. The clock starts on your first press, and that press counts. Held keys count once. If the tab is hidden or the window loses focus mid-test, the run is void rather than quietly wrong.

Browsers round event timestamps slightly for privacy, and mice and keyboards differ in how they report fast presses, so treat small differences between devices with care. Compare your runs on the same setup.

Scores

Your bests are saved in your browser's local storage and never leave your device. There is no leaderboard. The rating bands shown with results are this site's own scale, not population data: we have not found a published average CPS we can cite, and we will not invent one.
