Measured in the browser

Each test times your clicks and keys with the browser's high-resolution clock and shows how the number is worked out.

Tested

Every test is checked automatically in the three browser engines (Chromium, Firefox and WebKit), on phone and computer screens.

Your best scores

Your personal bests are kept in your own browser, so you can try to beat them.

Private

Nothing you click or type is sent to a server: the tests run on your device.
