Decks! is a program for memorizing foreign words. This app can improve your vocabulary boosting learning of any language through an incredibly clever algorithm. This algorithm was created by the German experimental psychologist Hermann Ebbinghaus. You can add any word and start learning trying to remember the translation. By pressing the buttons "Excellent", "Good" and "Again" you give information about the quality of knowledge to the algorithm, which will add or decrease time for reminding the repetition.
