Reaction Time Test: Are You Faster Than Average?

Reaction time here means the gap between seeing the colour change and your finger registering a tap. That includes your screen's refresh rate and your device's touch latency, so treat the number as a fun benchmark rather than a laboratory measurement.

Most people land somewhere between 250 and 350 milliseconds. Under 250 is genuinely quick. Tapping before the green appears counts as a false start — the test will make you redo the round.
