A free app for Android, by NDT.

The purpose of this dictionary is to provide a comprehensive, easy-to-use reference that contains clear, in-depth definitions of both Korean and English words. It provides definitions that include not only the meanings, but also the different ways in which words are used in various phrases. It is a dictionary that is both offline and free to use, with the definition of words updated every day. This makes it a useful tool for both learners and teachers.

The user interface is easy to navigate, and the entire dictionary can be searched using both the Korean and English languages. This makes it easy to look up the word that you want to know the definition of, even if you don’t know the exact spelling. The word that you enter into the search box will be displayed along with its definition, the sentence in which it is used, and a list of all the words that contain that letter.
