Understand the Korean you encounter, and remember what you learn.
Oegugin brings together an offline Korean dictionary, sentence explanations, private reading texts, complete source dialogues and vocabulary practice. No account is required.
START WITH SOMETHING USEFUL
Choose your goal and starting level. Explore a useful sentence, hear it, learn three words with their meanings, and finish a short practice. Continue at your own pace from Learn.
LOOK UP REAL KOREAN
Search 56,000+ entries by Korean word, English meaning or attested inflected form. See concise meanings first, then expand the full source definition, pronunciation, forms and examples.
UNDERSTAND A SENTENCE
Sentence Lens breaks Korean into words and explains likely dictionary forms, particles and endings. Alternatives and unknown forms stay visible. Open a word for more detail and return to what you were reading.
READ YOUR OWN TEXTS
Create a private text or import a text file or a PDF with selectable text. Tap words as you read, save useful vocabulary with its sentence, and resume your reading position later.
LISTEN IN CONTEXT
Explore complete source-linked dictionary dialogues with device pronunciation. The separate listening library includes 24 longer bilingual readings and 36 native recordings, available offline with slower playback.
LEARN WHAT YOU KEEP
Save the meaning and sentence you want to remember. Organize words into personal lists or choose a vocabulary pack. New words are introduced before recall; missed words return for another attempt. Pause a session and continue later without losing your place.
PRIVATE BY DEFAULT
Dictionary lookup, sentence analysis, reading texts, saved vocabulary and learning progress stay on your device. Oegugin does not upload searches or imported text. Optional analytics record feature use without your Korean content and can be turned off in Settings.
The free app includes dictionary lookup, learning and saved-word review, dialogues, listening, five new sentence analyses per day and up to two saved texts. Reopening an already explained sentence does not use another analysis. Oegugin Pro removes the sentence-analysis and saved-text limits. Apple handles payment and renewal.
