Lockademy: Korea Skrin Kunci

Turn every screen on into a Korean lesson. Lockademy displays a Korean word every time you turn on your phone — read, remember, swipe. No apps to open, no time to waste: the moment you spend unlocking your phone turns into dozens of micro-lessons a day.

The exclusive purpose of this app is to learn Korean on your lock screen. Everything else — word browser, stats, quizzes, and settings — exists solely to configure and track the learning experience on that lock screen.

HOW IT WORKS
• Turn on your screen — Korean word cards appear
• Tap to reveal meanings, example sentences, synonyms, and antonyms
• Mark "I know this" or "Show again" — smart repetition takes care of the rest
• Want to know more? Tap Ask AI to explore the word in Google AI Mode — nuances, 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

NOT GOOD AT READING HANGUL? START FROM ZERO
Can't read Korean yet? The built-in 한글 course teaches the alphabet itself: every vowel and consonant with mnemonics, step-by-step syllable construction (ㅎ + ㅏ + ㄴ = 한), final batchim, and real pronunciation rules — 한국어 is pronounced "hamnida", and the cards show you why. Select "I can't read Hangul yet" when you first open the app and it starts right from there.

SMART REVIEW THAT NEVER FORGET
Leitner's spaced repetition brings back every word right before you forget it: 1 hour → 1 day → 3 days → 7 days → 30 days. Words you know move back; words you get wrong come back earlier. Your progression and statistics stay motivating.

QUIZ MODE
Flip the card to Quiz and choose the correct meaning from four options. Instant feedback, hints, and quiz accuracy statistics to help you master. In the 한글 course, quizzes train letters: arrange syllables from their parts and match each letter to its sound.

20,000 TOPIK WORDS
Vocabulary curated from the National Institute of Korean Language student word lists and public TOPIK guidelines, covering every level from beginner to advanced (TOPIK 1–6). Each word is accompanied by romanization, word types, natural example sentences, and synonyms/antonyms. Browse the full word list, search, and bookmark words for revisiting.

MAKE IT YOURS
• Word level: basic Hangul alphabet, beginner, intermediate, or all
• Display frequency: every time the screen is on, every hour, every 3 hours
• Daily new word limit keeps repetition manageable — and reaching it never ends your session
• Quiet time — no cards at night
• Safe during alarm: cards don't appear when your alarm is going off or about to go off
• Swipe up from the bottom to hide cards, so system gestures like Samsung Wallet work
• Two daily reminders that are automatically skipped when you're done studying
• Card font size, romanization toggle, always-show-meaning option

PERSONAL AND FULLY OFFLINE
Everything works 100% offline. No accounts, no registration, and your learning data never leaves your phone.

Note: this app requests the "Display over other apps" permission only to show learning cards when the screen is on. It never covers other apps and never compromises your device's security.
