Our app measures how fast you really are. Wait for the screen to flash green, then tap as quickly as you can — but jump the gun and you'll have to wait again.
Five rounds give you an average reaction time in milliseconds, and the app remembers your personal best so you can train to beat it. Simple, addictive, and honest about your reflexes.
