About the test

This is a simple tool to measure your reaction time.

The average (median) reaction time is 215 milliseconds, according to the data collected so far.

If you want, you can keep track of your scores, and see your full history of reaction times.
Just do at least 5 clicks and then click save.

Clicks faster than 100 milliseconds will be saved, but they will not count towards your score on the leaderboard.
