## What is StackDrill?

StackDrill is a training app for magicians who want to master a memorised deck. It ships with Mnemonica and Aronson stacks built in, and you can add any custom stack of your own.

Learn a new stack from scratch using memory hooks: position pegs based on the Major System give each number a concrete image, and card images let you reconstruct the deck visually. Every association is editable, so you can make the hooks your own.

Drill across multiple modes:
• Card → Position: see a card, recall its position in the stack
• Position → Card: see a number, name the card
• Neighbours: recall the card just before or after
• Sequence: name the card that comes next
• ACAAN cuts: practice Any Card At Any Number scenarios
• Hands-free mode: drill without touching the screen

Smarter practice, not just more practice. Weighted card selection quietly brings back your weak cards more often — no manual flagging needed. Spaced repetition (Leitner boxes) keeps difficult cards in rotation until they stick.

Stats that persist between sessions: accuracy, streaks, daily streak, and a full per-card breakdown.

No account, no backend, no tracking. Everything stays on your device.
