Chinese Language Learning – Offline Audio Flashcards

A Chinese language learning app based on recall, vocabulary filtering, and offline learning.

🔎 Vocabulary Filtering
Each learning item has a category (word, phrase, sentence) and a set of tags describing its meaning, e.g., food, science, family, China, noun.

The app requires:

Category selection

The app allows you to:

Select required tags (the item must contain them)

Exclude tags (the item cannot contain them)
This allows you to easily create your own learning sets.

Example:

Category: word

Required tags: food + nationality

Excluded tags: Poland

Result:
✔ rice
❌ dumplings

If no tags are selected, the set will contain all items in the given category.
