TOPIK vocabulary, one glance at a time. A word waits in hangul with its romanization; one tap reveals the meaning and a real sentence.
The romanization shows on the question side, so you can say the word out loud without leaking the meaning.

doseogwan
A word from your pack, waiting on the screen you look at anyway.
“Doseogwan… a library?”
Say it before you tap. That small moment of recall is what makes it yours.
library
μ€νμ λμκ΄μ κ°μ.
Ohue doseogwane gayo.
I go to the library in the afternoon.
The beginner packs follow the official TOPIK I word lists; the higher packs follow the TOPIK II grade bands. Start where you are; let the widget carry you up.
Every pack opens with a free preview · another word unlocks daily
Every word shows its hangul with Revised Romanization right under it, so you can sound it out from day one.
Real examples with romanization and translation, so vocabulary lives in context instead of isolation.
Beginner packs follow the official TOPIK I lists. TOPIK II publishes no word lists, so higher packs follow the exam's grade bands, split by frequency.
No accounts, no tracking, notifications opt-in. Everything lives on your device.
Another word unlocks each day at no cost. Lock&Learn+ opens every pack at once, so the widget can walk you from your first hangul to the advanced bands.
Install Lock&Learn Korean, then touch and hold your Lock Screen, tap Customize, tap the widget area, and choose Lock&Learn Korean. A TOPIK word with its romanization will wait there every time your screen wakes. There is a Home Screen widget too.
Vocabulary runs from beginner to advanced. The beginner packs follow the official TOPIK I word lists; because TOPIK II levels are awarded by exam score rather than official word lists, the higher packs follow the exam’s intermediate and advanced grade bands. Beginner 1 is free.
Yes. The app is free on iOS: Beginner 1 is free, every other pack opens with a free preview, and another word unlocks daily. Lock&Learn+ is an optional upgrade that opens every pack at once, offered as a yearly plan with a free trial or a one-time lifetime purchase.
Revised Romanization appears under every word on the widget and everywhere in the app, so you can say each word out loud before the meaning is revealed. Pronunciation is never a guess.
There is no session to sit down for. The word waits on the screen you already look at dozens of times a day, you recall it before you tap, and the meaning arrives with a real example sentence. Learning happens in the seconds you were going to spend anyway.
No. There are no accounts and no tracking. Streaks, saves and progress live on your phone and nowhere else, and notifications are opt-in. More in the Privacy Policy or on the Support page.
