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. KNOW YOUR REAL SPEED • Median, best trial, average and consistency for every round • A chart of every trial • Progress charts and personal bests for each mode • Ratings from Warming Up to Elite COMPETE AND COLLECT • Game Center leaderboards for every mode • 12 badges to unlock • Share a score card and challenge your friends MADE FOR EVERYONE • Go is always a solid disc, not just a color change • Optional blue/amber palette for color-blind players • Light and Dark Mode on iPhone and iPad PRIVATE BY DESIGN No accounts, no ads, no tracking. Your results stay on your device.

Verdict
The clearest difference is ads: QuickBlink at none against Dynamic Visual Acuity's shown. QuickBlink also leads on update cadence (every 7 months vs every 39 months). Dynamic Visual Acuity's advantage is iOS requirement (14.1 vs 18.0). On price, in-app purchases and device support there is nothing between them.
