How the reaction time test works
- Tap the box to start. It turns red and waits for a random moment.
- As soon as it turns green, tap. Tapping while it is still red is too soon, and that try starts over.
- After five taps you see your average. Lower is better.
Most people score between 200 and 300 ms. Your screen, browser, and device add a little delay too, so compare scores on the same device.
The test reacts when your finger or mouse button goes down, not when it lifts.
