Mandarin Hero

Master Mandarin vocabulary with FSRS spaced repetition. Every word comes with an example sentence for context, plus stats on what to focus on. Fully offline.

Mandarin Hero allows you to permanently increase your vocabulary using smart spaced repetition and real-life practical sample sentences for all vocabulary. Context is king. Learn Chinese the way people actually speak it. Not the stiff, formal phrasing most textbooks default to.

WHY IT'S DIFFERENT Every example sentence is chosen for everyday, spoken-register Mandarin: common contractions and phrasing a native speaker would actually use in conversation. Not phrasing that's merely grammatically correct.

WHAT YOU GET • Full HSK 1-6 vocabulary, structured and ready to study from day one: no setup, no importing your own deck • Smart spaced repetition using FSRS, a modern, research-backed scheduling algorithm that adapts to how well you actually know each word • Browse by Character or by Word, with real example sentences and pinyin for every entry • Preview exactly which new words are coming up before you start a session • Fully offline once installed: review your cards anywhere, no connection required • No account, no sign-up screen, nothing to configure. Just open the app and start learning

HOW IT WORKS Each flashcard shows you a word or character; rate how well you remembered it, and the app schedules your next review automatically. Cards you find hard come back sooner, cards you know well come back later. Over time this means less wasted review time and better long-term retention than fixed-interval flashcards.

Whether you're preparing for an HSK exam or just want to actually speak Mandarin with real people, Mandarin Hero focuses on the language you'll actually use.
