Wengu: HSK Chinese Flashcards

Remember Chinese, forever. Wengu is the HSK flashcard app that schedules every word on your memory, not on a calendar. Powered by FSRS-6, the open-source algorithm Anki now ships by default, it brings a word back on the day you were about to forget it. Not a day early, not a week late. Start free with HSK 1 and HSK 2, forever. No ads, no clock, no card on file. WHY WORDS STAY Every card carries three numbers. Stability is how long the word survives in your head. Difficulty is how much work it costs you. Retrievability is the odds you recall it right now. FSRS-6 updates all three from your own answers, so the schedule follows your forgetting curve, not an average learner's. You review less and remember more, and a forecast chart shows exactly what tomorrow will ask of you. THE WHOLE HSK, ONE APP • 11,000 HSK 3.0 words across all seven bands, HSK 1–6 and the 7–9 band, plus the classic HSK 2.0 lists • Audio pronunciation, tone-colored pinyin and kaiti hanzi on every card • Example sentences that show each word in real use, with audio • 知新 Stories: narrated short stories written for your level, with tap-to-look-up words, new stories added regularly • 成语 Idiom books: curated courses of idioms with literal meanings, real meanings and the stories behind them • Practical Chinese: numbers, dates and the Chinese calendar A SESSION THAT FEELS GOOD • One gesture per card: swipe left for hard, right for good, up for easy • Tap to reveal, hear the word, move on.
