How the reaction test works
Wait for green
Don't guess! Tapping early triggers a false start and the round is repeated.
Tap instantly
We measure the time between the green signal and your tap, in milliseconds.
QUICK FACTS
What changes your reaction time?
Focus matters. Notifications, conversations, and even looking away for a moment can slow your response.
Your device matters too. Screen refresh rate and touch delay can slightly affect the number, so compare results on the same phone.
Practice helps. Your later rounds may be faster because your brain already knows what signal to expect.
This game is made for fun and friendly competition—not as a medical or professional reaction assessment.
