Lockademy 鎖屏學韓語單字

Every time you turn on your screen, it becomes a Korean lesson. "Lockademy" displays a Korean word when you turn on your phone screen—glance at it, think about it, and swipe away as usual. No need to open any other apps or schedule time: those dozens of times you turn on your screen each day are your study time.

The sole purpose of this application is to learn Korean on your lock screen. The word lists, statistics, quizzes, and settings are all solely for setting up and recording this lock screen learning experience.

■ How to Use

・Turn on your screen, and the word cards appear.

・Tap to display the meaning, example sentences, synonyms, and antonyms.

・Choose "I know" or "Look again," and let the AI ​​review the rest.

・Want to learn more? Tap "Ask AI" to use Google to look up the word's nuances, cultural background, and related usages.

・Unlock as usual. Learning cards will not affect PIN, pattern, or fingerprint unlocking.

■ Never know the Korean alphabet? Start from scratch.

Still can't understand Korean? The built-in Korean course will teach you the Korean alphabet itself: each vowel and consonant has a mnemonic rhyme, practicing step-by-step the formation of syllables (ㅎ + ㅏ + ㄴ = 한), the ending consonant (받침), and the actual pronunciation rules—합니다 is pronounced "hamnida," and the cards will tell you why. Select "I still don't understand the Korean alphabet" when you first open the app to start from there.

■ Review before you forget.
The Lightner Spaced Repetition Method (SRS) will bring words back to mind just when you're about to forget them. Review intervals: 1 hour → 1 day → 3 days → 7 days → 30 days. Longer intervals between memorized words mean you'll get back to words you answered incorrectly faster. Consecutive study days and learning statistics keep you motivated.

■ Quiz Mode Switch the cards to "Quiz" mode and choose the correct meaning from four options. Instantly find out if you're right or wrong, with hints and accuracy statistics. In Korean lessons, quizzes will be replaced with letter practice: combining components into syllables or matching letters to their correct pronunciation.

■ 20,000 TOPIK Vocabulary Words Selected based on the "Korean Language Learning Vocabulary List" from the National Korean Language Institute of Korea and publicly available TOPIK vocabulary guides, covering all levels from beginner to advanced (TOPIK levels 1-6). Each word includes Romanized spelling, part of speech, example sentences, and synonyms/antonyms. You can browse the complete word list, search, and save words you want to review.
