Frequently asked questions

What's a normal reaction time?
Most adults average between 200-300 milliseconds. Age, caffeine, focus, and even time of day affect your result. Younger people and athletes often test faster. It's worth testing several times since your first attempt may not reflect your actual baseline.
Can you improve your reaction time?
Yes, with practice and focus. Reaction time can improve slightly through repeated testing, especially if you're learning the specific pattern or stimulus. Some people see faster times after warming up. Genetics and age play a role, but attentiveness and training matter too.
Why would I test my reaction time?
Gamers and esports competitors track reaction time as a metric. Athletes use it for training feedback. It's also useful as a simple medical or cognitive baseline. Many people just enjoy the challenge or want to benchmark themselves against friends.
Is my data safe?
Yes. Your test results never leave your device—they're processed entirely in your browser. No accounts, tracking, or data upload required. Take the test as many times as you want with complete privacy.
