Frequently asked questions
What is a good reaction time?
Most people score between 200 and 300 milliseconds on a visual test like this one. Under 200 ms is very fast.
Why do my results vary?
Attention, fatigue and your device all matter. Mice, touch screens and monitors add a few milliseconds of delay of their own.
