Frequently asked questions
What is a reaction time test?
It measures how quickly you respond to a visual signal — usually in milliseconds (ms). Our test uses a random wait, then a green GO signal.
How accurate is this test?
We use performance.now() for timing. Results also depend on your screen, mouse, and browser. For fair comparisons, use the same device each time.
Is it free?
Yes — completely free, no account, no download. Play as many sessions as you like.
Can I improve my reaction time?
Yes. Sleep, focus, warm-up rounds, and regular practice help. Many users improve 20–40 ms over a few weeks.
Does age affect reaction time?
Reaction time tends to slow slightly with age, but practice and alertness matter more for day-to-day scores.
Where is my data stored?
Scores and settings are saved in your browser (localStorage) on your device. We do not upload your test results to our servers. Clear site data in your browser to reset everything.
Does Fast Reaction Test work on mobile?
Yes. The benchmark and tools are touch-friendly. Mobile screens may add a few milliseconds compared to a gaming mouse on desktop — compare scores on the same device for fairness.
Will you show ads?
We may display third-party ads (such as Google AdSense) to keep the site free. Ads are separate from the test timing engine and do not change how your reaction time is measured.
