Common questions
- What makes NidNoi different for learning Thai, Chinese, and Japanese?
- NidNoi is built for learning Thai, Chinese, and Japanese when you want real competence: standards-aligned courses (HSK for Mandarin, JLPT for Japanese, leveled Thai), practical language for daily life and work, and a path from scripts into culture, society, and advanced topics — so you can read, write, and speak with clear progress.
- Do I need an account?
- No. Progress is saved on your device automatically. Sign in with Apple, Google, or email (in the app or at nidnoi.dev/login) only if you want cloud backup and sync across devices.
- How much content is in the app?
- Thai: five levels with 1,600+ words, 150 reading passages, 55 dialogues, and grammar units. Chinese: five levels with 2,500+ words, pinyin/tones, Hanzi strokes, dialogues, and exercises. Japanese: hiragana and katakana, Units 1–19 classroom dialogues, and JLPT-aligned vocabulary.
- Why can't I hear lesson audio?
- Make sure your device volume is up and the language voices are enabled in system Settings → Accessibility → Spoken Content (iOS) or the equivalent on Android.
- How do I reset my progress?
- Delete and reinstall the app, or clear app data in system settings.
