About Reaction Time
The Reaction Time test measures how fast your reflexes are in milliseconds. Wait for the screen to turn green, then click or tap as fast as possible. The test runs five rounds and calculates your average. The average human reaction time is around 250 milliseconds — under 200ms is considered fast, and under 150ms is exceptional. Factors like caffeine, sleep, age, and practice all affect reaction time. Athletes, gamers, and pilots regularly test and train their reflexes. Flario's Reaction Time test is scientifically structured to give you a fair, repeatable measurement you can track over time.
How to Play
Click to start
Wait for green — random delay 1–4s
Click immediately when green
Too early = attempt cancelled
💡 Tips & Tricks
Hover hand before green
Focus on centre of screen
Breathe out while waiting — reduces tension
🏆 Scoring
Lower is better. Best time saved. Under 150ms = world-class.
Frequently Asked Questions
What is a good reaction time?
The average human reaction time is around 250 milliseconds. Under 200ms is faster than average, under 170ms is excellent, and under 150ms is in the top percentile. Elite gamers and athletes often score in the 150–180ms range with regular practice.
Can I improve my reaction time with practice?
Yes, to a degree. Regular testing and training can improve your reaction time by 20–40ms over several weeks. The biggest gains come from reducing anticipatory guessing and maintaining consistent focus. Sleep, hydration, and caffeine also measurably affect results.
Why does my reaction time vary between tests?
Reaction time naturally varies due to attention, fatigue, and the random timing of the green signal. A single result is not a reliable measure — your average across five rounds gives a much more accurate picture of your reflexes.
Is clicking faster than tapping on a touchscreen?
Mouse clicks and trackpad taps are typically 10–20ms faster than touchscreen taps because touchscreens add a small detection delay. For the most accurate measurement, use a mouse or trackpad on desktop.
Why does the green appear at a random time?
Random timing prevents you from anticipating the signal and clicking early. If the timing were predictable, the test would measure anticipation rather than true reaction speed.
How many rounds does the Reaction Time test run?
The test runs five rounds. After each round your time appears, and after all five your average is calculated and displayed as your final score. Your all-time best average is saved locally.
