Reaction Time Test

Wait for the color change, then tap as fast as you can.

Reaction Time Test

Random ready delay, false-start detection, median of attempts.

Your times appear here. Tapping before green counts as a false start, not a time.

How to use it

  1. Tap the pad to start.
  2. Wait for green, then tap.
  3. Repeat a few times to see your median and best.

Example

Five tries of 280, 250, 300, 265 and 310 ms give a median of 280 ms.

Good to know

  • Tapping before the change is a false start and isn't counted.
  • Screen and device delays affect results.
