Details
The reaction time test measures how fast you click the moment the screen turns green, in milliseconds. Human visual reaction averages 200-250 ms, and the test works as training or a warm-up.
Each session has 5 rounds. Clicking early (before green) is invalid and the round restarts. After 5 rounds, your average and your best time are shown.
Your best time is saved only in your device's local storage, giving you a target for next time. Everything runs in your browser and nothing is sent anywhere.
