MemoDeck is a premium training app for card magicians who want to learn, practise, and master memorized deck work with confidence. Originally created for Mnemonica users, MemoDeck now goes further with support for several well-known memorized deck systems, including Mnemonica from Juan Tamariz, Aronson from Simon Aronson, Memorandum from Woody Aragon, Rapsodia from Ruthguiller Dumont, and CHaSeD. You can also create your own custom stack and use it throughout MemoDeck, making the app suitable for virtually any memorized deck system. Whether you are starting your first stack or keeping your memory sharp between performances, MemoDeck gives you a structured, elegant, and practical way to train every day. Learn at your own pace through progressive training chapters, then strengthen your recall with Expert, Challenge, Time Trial, and ACAAN practice modes. Work from number to card, card to number, previous card, next card, random positions, speed drills, and more. Your learning progress is saved independently for each stack, allowing you to switch between different memorized decks without losing your progress. MemoDeck is designed as a serious practice companion for magicians — not as a shortcut to secrets. It does not reveal routines, methods, or explanations from any book or DVD. Instead, it helps you build the memory, speed, and confidence needed to use memorized deck work more naturally in your magic. Main features: • Built-in stacks: Mnemonica, Aronson, Memorandum, Rapsodia, and CHaSeD • Create and practise with your own custom memorized deck • Independent learning progress for each stack • Complete progressive training mode • Multiple Expert drills for fast stack recall • Multiple Challenge modes, including Four of a Kind Positions and the Quartet Principle • ACAAN training mode • Time Trial exercises to measure your speed • Score tracking and online score sharing • Available in English, French, Spanish, and German If you own books or courses about memorized deck magic, MemoDeck is the perfect companion to help you practise, retain, and improve your stack knowledge.
