This app is designed to be a learning tool for those interested in learning Mandarin Chinese. The app provides a variety of vocabulary lists for different proficiency levels, with definitions, synonyms, and antonyms. You can study each vocabulary in two ways: study and flashcards.

For the study mode, you must read and understand the definition and the example sentence to learn the vocabulary. For the flashcard mode, only the words will be displayed. It is up to you to reveal the pronunciation and the definition. You can also use the text-to-speech (TTS) function to help you learn the vocabulary.

The app also provides a variety of settings to help you use the app more effectively.
