Lockademy: Lock Screen Korean

Turn every screen-on into a Korean lesson. Lockademy shows you one Korean word each time you turn on your phone — read it, recall it, swipe on. No app to open, no time to set aside: the moments you already spend unlocking your phone become dozens of micro-lessons a day.

The exclusive purpose of this app is learning Korean on your lock screen. Everything else — the word browser, statistics, quiz and settings — exists only to configure and track that lock screen study experience.

HOW IT WORKS
• Turn on your screen — a Korean word card appears
• Tap to reveal the meaning, example sentence, synonyms and antonyms
• Mark "I know this" or "Show again" — smart repetition handles the rest
• Curious for more? Tap Ask AI to explore the word in Google AI Mode — nuance, cultural context and related expressions (regular Google search where AI Mode isn't available)
• Unlock as usual. The card never blocks your PIN, pattern or fingerprint

NEVER READ HANGUL? START FROM ZERO
Can't read Korean yet? The built-in 한글 course teaches the alphabet itself: every vowel and consonant with a mnemonic and audio, syllable building step by step (ㅎ + ㅏ + ㄴ = 한), batchim finals, and the real pronunciation rules — 합니다 is said "hamnida", and the cards show you why. Choose "I can't read Hangul yet" when you first open the app and it starts right there.

SMART REVIEW THAT NEVER FORGETS
Leitner spaced repetition brings each word back right before you would forget it: 1 hour → 1 day → 3 days → 7 days → 30 days. Words you know step back; words you miss return sooner. Your streak and progress stats keep you motivated.

QUIZ MODE
Flip the card to Quiz and pick the correct meaning from four choices. Instant feedback, hints, and a quiz-accuracy stat to beat. On the 한글 course the quiz drills letters instead: assemble syllables from their parts and match each letter to its sound.

20,000 TOPIK WORDS
Vocabulary curated from the National Institute of Korean Language learner word list and public TOPIK guidelines, covering every level from beginner to advanced (TOPIK 1–6). Every word comes with romanization, part of speech, a natural example sentence, and synonyms/antonyms. Browse the full word list, search, and favorite words to revisit.

MAKE IT YOURS
• Levels: 한글 alphabet basics, beginner, intermediate, or all
• Display frequency: every screen-on, hourly, every 3 hours
• Daily new-word cap keeps reviews manageable — and hitting it never ends your session
• Quiet hours — no cards at night
• Alarm-safe: the card stays away while your alarm rings or is about to
• Tap the lock clock to hear the time and date spoken in Korean
• Swipe up from the very bottom to hide the card, so system gestures like Samsung Wallet work
• Two daily reminders that skip automatically when you have already studied
• Card font size, romanization toggle, always-show-meaning option

PRIVATE AND FULLY OFFLINE
Everything works 100% offline. No account, no sign-up, and your study data never leaves your phone.

Note: the app asks for the "Display over other apps" permission only to show the study card when the screen turns on. It never covers other apps and never weakens your device security.

Start today — one word at a time, every time you look at your phone. 화이팅!
