情境英文單字記憶 第3冊 is a free Android app developed by shioulo under the Education & Reference category. This app aims to help users learn English vocabulary by providing detailed definitions, rich example sentences, phrases, related synonyms/antonyms/variations, and TTS pronunciation (American accent) for most of the words. It consists of 14 thematic units such as Clothing, Accessories, Furniture, Home Appliances, Tableware/Hardware, etc., each containing a large number of words sourced mainly from Yahoo Dictionary.

The app offers multiple testing modes (meaning, spelling, listening) and vocabulary review modes (normal, intensive, incorrect) to cater to different learning needs. It also provides a learning analysis curve to help users track their learning progress and identify areas for improvement. Additionally, the app uses intelligent learning assistance functions. It automatically adjusts the learning content for each unit based on users' reading progress, prioritizes the words that users need to review the most during vocabulary review exercises, and provides external or online searches for unfamiliar words in example sentences by long-pressing them.
