Description by Jeroen Meij(from the App Store)
Walk into the TOPIK already knowing every word on it.
Lock&Learn Korean puts real TOPIK vocabulary on your Lock Screen and Home Screen widgets, the screens you already check a hundred times a day. Each word arrives in hangul with its romanization, meaning, and an example sentence you would actually say, so the language settles in through your day instead of in one long sitting.
No account. No streak anxiety. Just the language, arriving quietly.
HOW IT WORKS - Add the widget to your Lock Screen or Home Screen - A new word appears each time you glance, rotating throughout your day - Tap any word for the full entry: hangul, romanization, meaning, and an example sentence with its translation - Move through the levels at your own pace
THE FEED Open the app and keep going: the Learn tab is your deck as a full-screen feed, one card at a time. Tap to flip a card, swipe up for the next word, swipe left to save it, swipe right when you already know it. Every example sentence carries its romanization word by word, right above the hangul. The scroll you reach for anyway, made of vocabulary.
QUIZ The Quiz tab deals your words back to back. Word rounds ask what a word means. Sentence rounds blank the word out of a real sentence. Listening rounds ask by ear: nothing to read, just the word spoken aloud. Getting one wrong never affects your progress. Choose whether rounds draw from the words you have met or your whole deck, and set each kind's clock, in Settings.
A QUIZ ON YOUR WIDGET, TOO Prefer a challenge before you even unlock? Flip the widget to a question. It shows you the word and asks what it means, then reveals the answer with one tap. A tiny test every time you check your phone.
YOUR OWN LISTS Every word carries a save button. Tap it to keep the word, hold it to file the word into a list of your own: travel words, exam words, the ones that keep slipping away. Your lists live in the Library, ready before your trip is.
YOUR PROGRESS A Progress screen in the Library counts the words you know and the words you have met, keeps your streaks, and fills one bar per level as you climb. A quiet answer to how it is going, with no dashboard in sight.
BUILT ON TOPIK VOCABULARY The word list follows the TOPIK levels, the standard framework for learning Korean, from your very first words up through the vocabulary of dramas, news and the workplace. Level 1 is free forever, the whole first level, no trial and no catch. When you are ready for more, Lock&Learn Korean+ opens every level.
MADE TO BE CALM - Notifications are off by default and always opt-in - Your progress stays on your device, no account needed - Save words with a tap, or file them into custom lists of your own - A calm, paper-like design that reads beautifully in light and dark
Lock your phone. Learn Korean anyway.
