A pure reflex trainer. A target appears at a random location: tap it the instant it shows. Your average reaction time is tracked across every round.
Wait for the green target circle to appear anywhere on screen. Tap it as fast as you can. After each tap you will see your reaction time in milliseconds. Complete all rounds to see your average and best times.
Tap every target as quickly as possible to minimize your average reaction time.
