Wengu
HSK flashcards that come back the day you'd forget them
Wengu schedules every Mandarin word on your own memory with FSRS-6, the algorithm Anki now ships by default. The full HSK 3.0 and classic 2.0 lists with audio, narrated stories, idioms, offline study and a Lock Screen widget. HSK 1–2 free forever, no ads.
Hi Product Hunt 👋 I'm Carlos, and I built Wengu because I kept losing Chinese words I had already learned.
Most flashcard apps review on a fixed calendar. Wengu reviews on your memory: every card carries three numbers (how long the word survives in your head, how hard it is for you, and the odds you recall it right now), and FSRS-6 updates them from your own answers. The word comes back the day you were about to forget it. It is the same open-source algorithm Anki now ships by default, in an app that needs no setup.
What's inside:
• The complete HSK 3.0 exam syllabus, 11,000 words across all bands, plus the classic HSK 2.0 levels, with HQ audio
• Narrated short stories written for each level, with tap-to-look-up words and hand-directed cover art
• An idiom track with the literal meaning, the real meaning and the story behind each one
• One gesture per card, offline from the first session, a Lock Screen widget that teaches a word every hour
• No ads, no tracking, and HSK 1 and 2 free forever
It is designed to feel like paper and ink rather than a game: warm xuan-paper, kaiti characters, one vermilion seal when you finish a session.
I would love your honest feedback, especially from anyone who has tried to keep a language alive on ten minutes a day. What made you stop using the last study app you tried?
