Saggio Technologies today announces Spanish Flashcards 2.0 – 1,000 Nouns for iOS, their app that uses prioritization to help students learn Spanish. Unlike other flashcards that simply repeat words, the app employs the Leitner cardfile system. It keeps three lists, based on student performance: Unseen (new), Correct (right once), and Mastered (right twice). Each time a new deck is dealt, cards from each group are included in a ratio of 50%-30%-20%. A scoring system tracks the student’s progress.
