Mandarin Lab

Mandarin Lab is a focused, offline-first learning path for practical Mandarin Chinese.

Work through 801 lessons covering HSK 1–6 and the combined HSK 7–9 advanced band. Each themed lesson combines a clear goal, vocabulary, a grammar pattern, a mini dialogue and a quick check. The complete 11,000-entry HSK 3.0 vocabulary collection is divided into manageable learning steps with Hanzi, Pinyin and English dictionary meanings.

The interface, lesson explanations and dictionary meanings are available in English, German, French, Spanish and Italian.

Features:

- 801 structured lessons across all nine HSK levels
- complete 11,000-entry offline HSK 3.0 vocabulary
- Chinese text-to-speech pronunciation
- Pinyin and five interface languages
- lesson progress stored only on your device
- related-lesson links and guided review
- optional Pleco dictionary lookup with Complete or a purchased level
- optional lesson-aware AI tutor using prepaid credit packs
- no account, advertising or analytics

HSK 1 is free. HSK 2, HSK 3 and HSK 4 are one-time single-level purchases; Complete unlocks HSK 2–9, the full offline vocabulary and Pleco lookup with one purchase. The AI tutor uses optional prepaid credit packs, not a subscription. Credit does not expire and is spent according to the actual cost of each answer; it includes no course content. The tutor sends only the message you explicitly submit, the current lesson context and interface language. Content purchases can be restored from the app; final localized prices are shown by the store.

Mandarin Lab is an independent learning app and is not affiliated with or endorsed by Chinese Testing International, the HSK examination operator, or Pleco.
