大學指考 英文單字 is an offline reading app that provides a comprehensive list of 2188 reference English words for the university entrance examination. The app gathers word definitions primarily from online sources and Yahoo Dictionary.

The app offers a smart learning mode that adapts to the user's reading progress in each unit. Users do not need to remember where they left off as the system automatically provides suitable words for each reading session, ensuring a balanced learning experience. Additionally, the system prioritizes words that the user needs to review during vocabulary review sessions.

With an analysis of the learning curve, users can easily track their learning progress. The app also provides unit performance analysis, allowing users to focus their time on the most crucial units for more effective learning. Moreover, users can long-press unfamiliar words in example sentences to perform external or online searches for further clarification.

The learning cycle of the app includes six major functions: Vocabulary Unit, Reinforce Vocabulary, Vocabulary Review, Self-assessment, Misspelled Word Review, and Learning Curve. This cycle enables users to effectively enhance their English vocabulary.
