Memory SoundX is suitable for everyone! A quieter kind of brain training. Memory SoundX takes the classic concept of pattern memory and refines it into a premium, focused daily exercise. By pairing distinct tones with vibrant colors, the game engages both your auditory and visual memory to improve attention, recall, and cognitive resilience. THE EXERCISE • Watch: A sequence lights up across the board, pairing each color with a distinct sound. • Listen: The game rewards auditory recall as much as visual memory, keeping the exercise crisp and multi-sensory. The tones are crafted to be pleasing and memorable. • Repeat & Master: Tap the pattern back, build longer runs, and train daily to sharpen your mind. FROM 3×3 TO 8×8 Start on a calm 3×3 board and grow into 4×4, 6×6 and the 8×8 endgame. On bigger boards, same-colored tiles repeat, so you have to remember where, not just what. RISE THROUGH THE RANKS Win streaks take you from Beginner to Pro, Expert and Legend. DAILY CHALLENGE & SURVIVAL A new Daily Challenge every day with a streak to keep, and a Survival mode that races the clock. COMPETE Compare your best runs and daily streaks on the Game Center leaderboards. MEMORY SOUNDX PRO The 3×3 and 4×4 boards, Survival and the Daily Challenge are free. Pro unlocks the 6×6 and 8×8 boards right away, the Expert and Legend ranks, and the All-Time leaderboard. Choose Annual (with a free trial for eligible new subscribers), Monthly, or a one-time Lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage them in your Apple ID settings. SIMPLE BY DESIGN Memory SoundX respects your focus and your data. There are no ads, no in-app account and no tracking. Just open the app and play.
