Reflex — frequently asked questions
What is a good reaction time?
For a visual click test, around 200–250 milliseconds is typical for adults; under 200 ms is fast.
How do I improve my reaction time?
Stay relaxed but focused, watch the whole panel rather than staring at one point, and don’t anticipate — react only once it actually turns white.
Is the reaction test free?
Yes — it is completely free, with no download and no sign-up.
