Stack Trainer

Practice Mnemonica and other stacks by sharpening your recall with fast daily drills, Awards & Personal Bests. You can also learn Mnemonica with a one-time Pro unlock.

Train your recall of Mnemonica and other memorized decks with Focused Daily Drills, Awards, Personal Bests, Apple Watch practice, and a one-time Pro unlock. Now you can also learn the Mnemonica Stack with the same one-time Pro unlock.

Stack Trainer is the memorized-deck training app for magicians who want to build genuine, performance-ready stack fluency. Start by learning Mnemonica through an interactive PAO Peg course, then sharpen recall, speed and confidence with focused daily practice.

The new PAO Peg Training teaches the stack card by card using vivid Person, Action and Object memory links, visual reinforcement, guided questions and active recall. Free users can experience the first five Mnemonica cards; unlock Pro to continue the complete course and turn your training into a full-stack skill.

Whether you are learning your first memdeck or keeping an established stack sharp, Stack Trainer gives you a structured path from knowing a card to using it under pressure.
