The "국립국어원 표준국어대사전" is an Android application developed by Ubimemes Research K-Lab. This free app allows users to easily search for the latest information using the OpenAPI of the National Institute of Korean Language's Standard Korean Language Dictionary.

With this app, users can conveniently search for the standard Korean language dictionary, which serves as the basis for the Korean language in South Korea. In addition, the app provides a direct link to the National Institute of Korean Language's Standard Korean Language Dictionary website, allowing users to access additional information or correct any potential errors or deficiencies in the search results provided by the OpenAPI.

The app also offers a feature to learn Korean language, providing easy access to some contents of the National Institute of Korean Language's online newsletter, "쉽표,마침표." Furthermore, users can enjoy a fun game to learn "오늘의 사자성어" (Today's Four-Character Idiom) that is presented daily, making language learning a playful experience.
