Lockademy Koreano Lock Screen

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

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

HOW IT WORKS
• Unlock the screen — a Korean word card appears
• Tap to show the definition, example sentences, synonyms and antonyms
• Mark "I know" or "Show again" — smart repetition does the rest
• Want to know more? Tap Ask AI to explore the word on Google — nuance, cultural context and related expressions
• Unlock as usual. The card never blocks your PIN, pattern or fingerprint

CAN’T READ HANGUL YET? START FROM ZERO
Can’t read Korean yet? The built-in 한글 course teaches the alphabet: each vowel and consonant has a mnemonic, syllable formation step by step (ㅎ + ㅏ + ㄴ = 한), batchim, and real pronunciation rules — 한국어 is pronounced “hamnida”, and the card shows you why. Select “I don’t know how to read Hangul” when you first open the app and you’ll start there.

SMART REVIEW THAT NEVER FORGET
Leitner spaced repetition brings back each word before you’ve forgotten it: 1 hour → 1 day → 3 days → 7 days → 30 days. Words you know recede; those you got wrong come back sooner. Your streak and progress stats keep you motivated.

QUIZ MODE
Flip the card to Quiz and choose the correct meaning from four options. Instant feedback, hints, and a quiz-accuracy stat that you must beat. In the 한글 course, the quiz trains letters instead: build syllables from their parts and match each letter to its sound.

20,000 TOPIK WORDS
Curated vocabulary from the National Institute of Korean Language's learner word list and public TOPIK guides, covering every level from beginner to proficient (TOPIK 1–6). Each word includes romanization, part of speech, natural example sentences, and synonyms/antonyms. Browse the entire word list, search, and favorite words for review.

MAKE IT YOURS
• Word level: basic Hangul alphabet, beginner, intermediate, or all
• Display frequency: every screen turn, every hour, every 3 hours
• Daily new word limit keeps review manageable — and reaching it doesn’t end the session
• Quiet time — no cards at night
• Alarm safe: cards don’t appear when your alarm is ringing or about to ring
• Swipe up from the bottom to hide the card, allowing system gestures like Samsung Wallet to work
• Two daily reminders that automatically skip when you’re done studying
• Card font size, romanization toggle, always-show-meaning option

PRIVATE & FULLY OFFLINE
Everything works 100% offline. No accounts, no sign-ups, and your study data never leaves your phone.

Note: The app requests the "Display over other apps" permission only to display the study card when the screen is turned on. It never covers other apps and never compromises the security of your device.

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