Twice As Hard Trainer forms part of a comprehensive suite of apps that dedicate to technical learning tools for close-up magicians. Twice as Hard Trainer addresses those who are familiar with the concepts related to Aronson, Tamariz, Nikolas in general, and the Twice as Hard plot in specific. If you know what these names relate to, and you apply the according techniques, then this app will help you stay tuned and inspired. A radical slim design. Cycle through the logical phases of the challenges at hand. Name it the 'virtual spectator' concept. Approaches: - Simon Aronson's 'Twice as Hard' Plot and his 'Undo Influence' concept - Jean-Marie Beckers's 'Inverse Influence' Credits: - credits to Simon Aronson for both 'Twice as Hard' and 'Undo Influence'.

For details about 'draH sa eciwT', and the inverse version refer to Jean-Marie Beckers, Undo Influence Generalization, 2015. - I like to thank Simon Aronson and Jean-Marie Beckers for the permission to use their ideas for this commercial app. Some Features: - Aronson, Tamariz and three user defined ones - display and whisper modes - includes the quick-touch interactive analyser visualising the solution path and allowing for self imposed problem statements. 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, a number, think, act, check, and again. Swipe, swipe, think, verify. Swipe Twice, and again.
