Stack Lab - Memdeck Fluency

Jafo Digital Magic LLC

About this app

Stack Lab is a practice tool for card magicians learning a memorized deck.

Achieving memdeck fluency means recalling any card's position, and any position's card, instantly and under pressure. There can be no mental fumbling while your audience stares at you. Stack Lab replaces the grind of hundreds of hours with practice that schedules itself, puts your effort on the cards you actually struggle with, and defers the ones you already know.

It's the smartest memdeck trainer out there.

VOICE MODE: PRACTICE OUT LOUD
Stack Lab is the only memdeck trainer with a hands-free voice mode. You get to run through the cards you're working on while driving. You can practice while doing things around the house, working at your desk, cooking, or even jogging around the block - screen locked. Use the iPhone's own microphone or your Bluetooth earbuds.

This is the most efficient system for improving your stack recollection.

Speech recognition runs entirely on your iPhone. Nothing you say is recorded or sent anywhere, and it works with no signal at all.

SIX STACKS INCLUDED
• Mnemonica
• Aronson
• Redford
• The Particle System
• Boris Wild
• Memorandum

Each is included with the permission of its creator. Whichever one you choose becomes your stack throughout the app. You can also import your own from a simple text file, and a stack of your own design works exactly like a built-in one.

PRACTICE THAT SCHEDULES ITSELF
Stack Lab uses a modern spaced repetition algorithm. It decides what to show you and when. Cards that take longer to recall come back sooner. Cards you recite quickly take a back seat. New cards are released gradually, so the workload stays steady instead of swamping you in week one and starving you in week three.

You never have to plan a session. Open the app and it already knows what you should be working on.

ANSWER YOUR WAY
Drill card to position or position to card. Answer on a keypad built for the job, or spin the card dial. Start with a short warm-up of your first ten cards and grow your hand from there.

SEE WHERE YOU ACTUALLY STAND
A progress view shows every card in the deck and how solid each one is, so weak spots are obvious at a glance rather than a vague feeling. Progress is measured by how durable your recall is, not by how many sessions you have logged. Achievements mark the milestones along the way.

STACK REFERENCE
The full stack, always at hand, sorted by position or by card. For when you just need to look something up.

YOUR DATA STAYS YOURS
No account, no subscription, no sign-up, and no ads. Everything runs on your iPhone, including the scheduling and the voice recognition. Pay once and use forever. Back up your progress to Files or iCloud Drive whenever you like, and restore it on a new phone.

BUILT FOR PRACTITIONERS
Stack Lab is a tool, not a game. It assumes you are serious about the craft and pushes you toward memdeck fluency.
