"The Memory Project" is an app that helps the user to learn and memorize a key-value pair map. That is, it trains and tests the user's ability to associate letters=keys with digits=values. I am really impressed with the aesthetics of the app and the pleasant training and testing exercises that incorporate visuals, audio, and handwriting. Their new custom map feature is quite nice too. :)
