Quizlet is a widely-used educational app that simplifies studying through flashcards, quizzes, and games. Its primary strength lies in its massive library of user-generated study sets for a wide variety of subjects, including languages. While it offers a "Learn" mode that spaces reviews, its algorithm is generally considered less rigorous than dedicated SRS tools like Anki. Quizlet is excellent for quick vocabulary review and its game-like modes make practice more engaging, serving as an accessible option for learners who find other systems too complex.
