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.

In addition to measuring your reaction time, this test is affected by the latency of your computer and monitor. Using a fast computer and low latency / high framerate monitor will improve your score.

This is discused in further detail on the the statistics page. While an average human reaction time may fall between 200-250ms, your computer could be adding 10-50ms on top. Some modern TVs add as much as 150ms!

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