Train Mnemonica and other memorized deck recall with focused daily drills, Awards, Personal Bests, Apple Watch practice, and a one-time Pro unlock. Stack Trainer is a memorized deck practice and recall trainer for magicians. It helps you build, practise, and retain memorized deck stacks, also known as memdecks, including Mnemonica, Aronson, Redford, Particle System, Memorandum by Woody Aragón, Nikola Card System, Joyal and custom-built stacks. Stack Trainer is designed for recall training, stack fluency, and long-term retention. It is not a full magic course or a replacement for published stack-learning material. Instead, it gives you the tools to drill cards, positions, sequences, weak areas, and performance-style scenarios in a structured way. If you are new to memorized deck work, you can start small by using filters to practise only a few cards at a time, then gradually expand as your recall improves. PAO (Person, Action, Object) memory links, hints, notes, photos, and focused repetition can help support your learning process as you build toward full-stack confidence. Learning a stack is hard. Keeping it sharp is harder. Stack Trainer uses retrieval practice, spaced repetition, adaptive card prioritization, visual reinforcement, awards, streaks, personal bests, and performance tracking to turn fragile recall into practical fluency. Train daily with focused practice sections designed around how magicians actually build stack skill. --- Practice Modes: Core Recall (Build instant card and position recall) * Recall: Position — train card-to-position and position-to-card recall * Recall: Sequence — train next and previous card recall Stack Fluency (Strengthen speed, accuracy, and whole-stack confidence.) * Matchup — timed card-to-position memory game * 4 of a Kind — match ranks to their stack positions * Stack Segments — learn where cards generally live in the stack * Rebuild Stack — move cards back into correct stack order, either in Grid format or in traditional Card Fan format Practical Stack Work (Apply your stack knowledge in performance-style scenarios.) * ACAAN — practise Any Card at Any Number thinking * Improv — train flexible cut, count, and reveal thinking for memorized-deck performance with Pro Version --- Free Features * Practise the Mnemonica stack at no cost * Daily reminders, streaks, and habit tracking * Earn Awards as you build consistency * Track Personal Bests, Trends and Recent Sessions * Train Core Recall and selected stack practice modes * Use filters to practise small groups of cards at a time * Start learning progressively by drilling only the cards you are currently working on Memory Support * PAO: Person / Action / Object memory links * Custom PAO entries * In-game hints linked to PAO entries * Notes and photos in Learn Stack mode with Pro Version * Spaced-repetition-based training using Adaptive Card Prioritization with Pro Version Performance Tracking * Score, accuracy, recall time, and session stats * Personal Best tracking with timestamps * Awards across consistency and mastery * Card Mastery Heat Map and performance trends * Focus Cards showing recently missed and weak cards that need attention * Adaptive practice insights with Pro Version to help identify cards needing more review and practice Apple Watch * Practice on your wrist * View all stacks for easy recall Pro Features * Adaptive card prioritization and spaced-repetition-based training * Additional stacks: Redford, Aronson, Particle System, Memorandum by Woody Aragón, Nikola Card System, Joyal * Custom stacks — build your own * Additional Practical Stack Work modes including Improv including random starting cut option for practising from different bottom-card positions * Extra options in some game to support stronger speed and card placement training * Notes and photos in Learn Stack mode * Cloud sync for backup and restore * Future Pro features Train daily.
