TongTong - Learn Chinese

Learn Chinese the smart way!

TongTong helps you build real Mandarin vocabulary and actually keep it. Instead of cramming, TongTong schedules every word for the exact moment you're about to forget it, so each minute of study counts.

STUDY THAT STICKS • Adaptive spaced repetition (FSRS + Item Response Theory) learns how fast you forget and reschedules each word individually — no fixed decks, no busywork • Clean flashcards with simplified characters, Hanyu Pinyin, and English meanings • Native-speaker audio for every word and example sentence — tap to replay anytime • Real example sentences: tap any word in a sentence for an instant definition • "Easily confused" words shown side by side, so 比 and 避 never trip you up again • Measure words, parts of speech, and traditional variants where it matters • Tricky "leech" words flagged so you focus where it counts

START AT THE RIGHT LEVEL • A quick adaptive placement quiz finds your HSK level on day one — never bored, never overwhelmed • Words tagged HSK 1–6 and 7–9, from first steps to advanced fluency

SEE YOUR PROGRESS • A daily streak that rewards consistency over cramming • An ability rating mapped to the HSK scale, with a 90-day trend • Retention %, total words learned, and what's due today — all on one home screen

LISTEN AND LEVEL UP • TongTong Talks: Mandarin podcasts sorted by HSK level • Synced transcripts with word-level timing — tap a line to jump straight to it • "Before you listen" vocabulary so you're ready for every episode

BUILD YOUR OWN LIBRARY • Search the full corpus by character, pinyin, or English • Add any word to your study pipeline in a tap • Full word detail: definitions, audio, examples, and your personal review stats
