Reaction Test
A simple browser reaction speed test that saves your best score locally.
Do not click early. Wait until the box turns amber and says Click now.
How it works
Press start, wait through a random delay, then click as soon as the amber signal appears.
The score is the browser-measured time between the signal and your click or tap.
Tips
- Keep your pointer or finger ready, but do not click before the signal.
- Compare scores on the same device for the fairest trend.
FAQ
What is a good reaction time?
Many casual browser scores land around 200 to 350 ms. Your device, display, mouse, sleep, and focus can all affect the result.
Why did an early click fail?
The test only counts clicks after the screen tells you to click. Early clicks are blocked so the score stays fair.
