Reaction Time Test

Tap the screen as fast as you can the moment it changes from red to green. Your record is the average of 3 reaction times. A typical adult's visual reaction time is between 200 and 300 ms, and it can vary by tens of milliseconds depending on the device and screen.

How to play

1. Tap the screen to start, and a red screen appears.
2. Tap the moment it turns green.
3. If you tap before it turns green, that round starts over.
4. Your average reaction time over 3 rounds is your record.

Tips for a better record

• Watch the center of the screen and keep your finger just above it.
• Turning off low-power mode makes the screen respond a little faster.
• When competing with a friend, playing on the same device is the fairest.
