Get the most out of your Apple Watch to learn German or Spanish. Learn words with the method of flashcards, invented by Sebastian Leitner, which is one of the most effective methods of learning a foreign language. This application for flashcards on your watch uses a system with 5 successive boxes. As you progress in learning, the words you already know will go from one box to the next and appear on the display of your watch less and less frequently. The goal of learning is to get all flashcards into the last box. The advantage of this method is that the learner can focus on the most difficult flashcards, which remain in the first few boxes. The result is, ideally, a reduction in the amount of study time needed. Another function of the application is displaying additional words to learn on the watch face every 10 minutes (in complications). Learn by using your watch, it’s like always having your box with flashcards with you!
