iMemory is a brain training app built on classic cognitive science paradigms. Four powerful games target different aspects of your memory: • Dual N-Back — Train working memory with simultaneous visual and audio challenges. Recognize patterns from N steps back and push your limit higher. • Chimp Test — Test your spatial memory. Numbers flash briefly, then you recall them in order. Can you beat the chimpanzee? • Simon — Strengthen sequence memory. Follow an ever-growing pattern of colors and sounds. One more step each round. • Memory Match — Sharpen visual memory. Cards appear face up for a few seconds — memorize them, then flip to match every pair and clear the board. TRACK YOUR PROGRESS Every session is recorded. See your stats, streak days, and personal bests — all stored privately on your device. DESIGNED FOR DAILY USE Quick sessions, clean interface, and instant feedback make it easy to build a daily brain training habit. iMEMORY PRO Upgrade to iMemory Pro with a one-time, lifetime purchase and enjoy the full premium experience.
