About Reaction Test
How fast are you, really? The Reaction Test measures the time between a visual signal and your tap, in milliseconds. Average human reaction to a visual stimulus is around 250 ms — beat it.
How to Play Reaction Test
- 1Tap to arm the test; the panel turns red — wait.
- 2After a random 1.5–5 s delay it flashes green.
- 3Tap the instant you see green; your time is measured in milliseconds.
- 4Tapping early on red resets the attempt.
Tips & Strategy
- ◆React to the colour change with your eyes relaxed on the centre — do not anticipate.
- ◆Use a finger already resting on the screen; travel distance adds real milliseconds.
- ◆Take five attempts and trust the average — single readings swing wildly.
Frequently Asked Questions
What is a good reaction time?
Under 250 ms is average, under 200 ms is quick, and under 170 ms approaches esports-level reflexes. Touchscreen latency adds a little to every reading.
Why is there a random delay?
A fixed delay would let you count instead of react — randomness guarantees you are measuring genuine reflex.
Does age affect reaction time?
Yes, it slows gradually with age — but regular practice measurably sharpens it at any age.
