QuickBlink tells you how fast you really are, down to the millisecond. Wait for the signal. Tap. See your time. Then do it again, faster. FIVE WAYS TO PLAY • Classic: tap the instant the screen turns green. • Hold & Release: keep your finger down and let go on the signal. • Decoy: fake flashes try to bait you. Only the solid disc means go. • Choice: four pads, one lights up. Hit the right one. • Sound: eyes off the screen. React to the beep. DAILY CHALLENGE A featured mode every day. One shot. Build your daily streak. FAIR, ACCURATE TIMING Every signal is drawn on an exact display frame (up to 120 Hz on ProMotion displays), and your response is read from the touchscreen's own timestamp. Reactions under 100 ms count as guesses, just like false starts in sprinting.
