Centuries-Old Memory Methods Used in iOS App, Memorize IDi
Memorize IDi is a mnemonic calculator that helps turn number sequences into simple images to help expand and extend the capacity of one's memory. IDi Creative claims that the app will turn "any user into a number memorization prodigy."
The app is based on a method created by French mathematician, Pierre Herigone, in 1644. His methods are still used in memory training techniques and by "memory prodigies" that compete in world championships. The developers claim that the method hasn't become as widespread in the last few centuries because of its difficulty to carry out. iOS devices provide a perfect platform for this method and therefore, Memorize IDi will help spread these techniques with the training in its app.
The app is avaible in both iPhone ($2.99) and iPad ($3.99) versions.
