HSK Chinese Flashcards is the smartest way to master Mandarin vocabulary at every level. Whether you're just starting out or pushing toward HSK 6, the app has you covered with thousands of words drawn directly from the official HSK curriculum. Each flashcard shows you the Chinese characters and challenges you to recall the meaning before flipping to reveal the pinyin pronunciation and English translation. A built-in narrator reads every word aloud in natural Mandarin so you build the right sounds from day one. Tap the characters on the back of any card to hear the word again as many times as you need. Highly customisable to your own needs! Toggle narration, additional review cards, and much more! The app uses a spaced repetition system that tracks how well you know each word and automatically schedules reviews at the optimal time, so you spend less time on words you already know and more time on the ones that need work. Rate each card from Again to Very Easy and the algorithm adapts to your pace. Set a daily goal, track your streak, and watch your vocabulary grow across all six HSK levels. The word list view lets you browse every word by status, so you always know what you have mastered, what is in progress, and what still lies ahead.
