About this app

This is a vocabulary app for engineers to use in their work. You answer 30 multiple-choice questions per day.

It includes 2,500 words, phrases, and sentences actually used in five situations: chat replies, standard document phrases, meeting management, explaining systems, and casual conversations with colleagues.

Each 30-question set consists of 10 words, 10 phrases, and 10 sentences. Questions are presented in both Japanese-to-English and English-to-Japanese formats, and the English is also read aloud. The short explanations after the answers often offer "aha!" moments.

Examples include: "hold off on" (to pause) and "hold on" (wait a moment), "loop in" (to include Alex in the conversation), and "rain check" (to postpone this time, maybe next time). The app compiles phrases that are easy to say in Japanese but often stumble over in English, categorized by real-world situations.

No ads, no account required, no data collection, and no internet connection needed. Learning records are saved on your device and not transmitted externally.
