ST Unitas brings us 선재국어 30일 정리 공무원 국어 필수 암기APP, an education and reference tool that aims to help users learn and memorize essential vocabulary for the Korean civil service exam. The app features the basics of Korean spelling and grammar, as well as a selection of commonly used Chinese characters. It offers a curated list of words and phrases that are frequently used in the exam, and organizes them into a 30-day study plan.

The app does not require any mandatory or optional access permissions. It is compatible with Android 9.0 and later versions. If you have any questions or concerns, you can contact the developer by phone or visit their online cafe.
