Practice and review
Use feedback, not guesswork
Answer first; the app then shows Chinese, pinyin, and the translation. Incorrect items return later in the session and feed the review queue.
- Quick practice: up to five questions.
- Full practice: mixed recognition, listening, typing, matching, and sentence tasks.
- Flashcards: reveal the answer, then rate your recall honestly.
- Writing: trace or write with touch, mouse, or stylus, then print if needed.
Spaced review
Review timing is calculated on this device. Strong answers increase the interval; mistakes bring an item back sooner.
Pinyin and audio
Show or hide pinyin in Settings. Mandarin audio uses the voices available in your browser and operating system.
