Description by Ralph Cos Written by the developer, not by AppBrain. Click to read.
Stack Trainer forms part of a comprehensive suite of apps that dedicate to technical learning tools for Close-up magicians. Stack Trainer addresses those who are familiar with the concepts related to Aronson, Tamariz, Nikolas. If you know what these names relate to, and you apply the according techniques, then this app will help you stay tuned and inspired. 

Stack Trainer provides a most realistic card deck experience.

It sets the golden standard for mnemonic deck training.

A radical slim design.

Cycle through the logical phases of the challenges at hand. Name it the "virtual spectator" concept.

Approaches:
- Next Card: Sequentially displayed, name the next card
- Each Card: Name each card's position in a shuffled stack
- Each Position: Name each position's card in a shuffled stack
- Get Position: Name the position of a given card
- Get Card: Name the card at a given position
- Next Suit: Name the distance to the next of the same suit
- Wrong Card: Identify the one card that is displaced in the face-up spread stack
- Missing Card: Find the missing card in the face-up spread stack
- Spot: Spot a specific card in the face-up spread stack
- Highest Card: Identify the high and low cards of a random sub-stack
- Four of a Kind: Name the distance to the next of the same kind

Filters:
Filters can be set to reduce the actual stack to a substack of lower size addressing and supporting the gradual progress during the early learning phase of a stack. Filters also provide different perspectives onto a stack to inspire and engage expert users. These filters, applied to the chosen approach, can be set:
- ranges 1-13, 14-26, 27-39, 40-52, and a custom range
- pair and impair positions
- red and black cards
- any of the four suits
- court and number cards

Some Features:
- Aronson, Tamariz and user defined stacks
- Lorrayne's peg words for the 52 cards and 52 positions, plus 3 user defined sets
- display and whisper modes
- includes the quick-touch interactive analyser visualising the solution path and allowing for self imposed problem statements with decadic and tridecadic layouts
- feedback driven development
- feels almost like a true deck of cards. Practicing card magic you don't want no complicated, overloaded and distracting user interface. Less is more.
- probably the most complete, and straightforward solution available.

A card, the one downwards (or upwards), maybe its mates, maybe the next one of the same suit. Either on random walk, or deliberate choices on the complete map. Touch swipe, swipe. Swipe and again.

To experience the look and feel of 'Stack Trainer' load the free 'Random Input' app available by this developer.
