Training apps for people who memorized a deck of cards on purpose.

Trains your card recognition speed with scrolling spread challenges and rapid-fire 60-second quizzes. Track times and accuracy across sessions as your eye gets sharper and your reactions faster — card skill-building as a competitive sport.

A practice app for Pit Hartling’s "Sherlock" from In Order To Amaze. Simulates two riffle shuffles and a cut, then presents the spread so you can work all three elimination passes against a timer. Keep the "Looking For" display and stack-number overlays on while learning, then turn them off as you approach performance speed.

For every value in Mnemonica, one suit leads — and knowing which one is the key to locating all four cards fast. Drills the starting suit and the gaps between each group of four, building the positional awareness behind effects where you produce or control four of a kind from a memorized stack.

Trains the shift process used in ACAAN handling (as well as other effects): named card, existing position, named position, shift calculation, then the card to cut at. Practice without pressure, or solve 10 shifts against the clock and chase a personal best.

A simple, focused drill: given a card, how many characters are in its name? Trains the mental shortcut certain Mnemonica routines depend on. Tap in your answer and move on — pure speed repetition.

A clean random playing card and position generator. Tap to generate any of the 52 cards, a position from 1 to 52, or both at once — a quick, no-fuss generator for stage or practice. Hidden inside is a Mnemonica-powered force mode that silently outputs a matching card/position pair from the stack.

IYKYK. The classic effect on iOS: solicit random numbers from the audience, then turn the phone upside down and have a spectator tap for the final "random" number. Everyone can follow along on their own phone doing the math.

The best app for learning and practicing the Mnemonica stack. Plenty of games, and you can drill effects like Mnemonicosis and Asi Wind’s ACAAN with the shift.
