About KLKK

KLKK is a free suite of browser tools for gamers who care about speed and precision. Measure your click speed, test your reaction time, train your aim, convert your mouse sensitivity between games, and check your mouse for faults — all in a couple of clicks, with no download or account.

We built KLKK because the tools that already existed were slow, cluttered with ads, or inaccurate. Timing here is measured with the browser's high-resolution clock for millisecond precision, the interface is fast and clean, and your results stay private in your own browser.

Whether you're a Minecraft PvP player chasing a higher CPS, an FPS player dialing in your aim, or just settling a "who clicks faster" argument with a friend, KLKK is built to be the quickest, most accurate way to find out.
