Lockademy 锁屏学韩语单词

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 for a moment, and swipe away as usual. No need to open any other apps or schedule time: the dozens of times you turn on your screen each day are your study time.

The sole purpose of this app is to learn Korean on your lock screen. The word list, statistics, quizzes, and settings interfaces are all solely for configuring and recording this lock screen learning experience.

■ How to Use

・Turn on your screen, and the word card appears.

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

・Choose "I know" or "Look again," and let the intelligent review process handle the rest.

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

・Unlock as usual. The learning card will not affect PIN, pattern, or fingerprint unlocking.

■ Completely unfamiliar with Korean letters? Start from scratch.
Still can't understand Korean? The built-in Korean lessons teach you the Korean alphabet itself: each vowel and consonant comes with a mnemonic rhyme, guiding you step-by-step through spelling syllables (ㅎ + ㅏ + ㄴ = 한), ending sounds (받침), and the actual pronunciation rules—합니다 is pronounced "hamnida," and the cards explain why. Start by selecting "I don't understand Korean alphabet yet" when you first open the app.

■ Review Before You Forget
The Leitner Spaced Repetition Method (SRS) brings words back to mind just as you're about to forget them. Repetition intervals: 1 hour → 1 day → 3 days → 7 days → 30 days. Longer intervals between memorized words mean you'll get back to words you got wrong faster. Continuous study days and learning statistics keep you motivated.

■ Quiz Mode
Switch the cards to "Quiz" and choose the correct definition from four options. Instantly find out if you're right or wrong, with hints and accuracy statistics. In the Korean language course, quizzes will be replaced with letter practice: spelling parts into syllables or matching letters with correct pronunciations.

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