Every time you turn on your screen, you can naturally review the words and sentences you are currently learning. Repeated exposure builds up without needing extra study time. Check words on your lock screen, then reinforce them inside the app with flashcards and quizzes. Vocabulary learning becomes lighter, easier, and more consistent.
