GOAT HSK is an offline flashcard app for the official HSK 2021 vocabulary standard all 11,000+ entries across levels 1 through 9, in one app, with no account, no subscription, and no tracking. Built around modern spaced repetition (FSRS-5), it adapts to how well you actually remember each word, so reviews stay on schedule without flooding you with cards you already know.
