About this app

Turn every screen-on into a Korean lesson. Lockademy shows you a Korean word every time you turn on your phone—read it, look it up, swipe to the next one. No app to open, no time to carve out: The moments you already spend unlocking your phone become dozens of mini-lessons a day.

The sole purpose of this app is to help you learn Korean on your lock screen. Everything else—the word browser, statistics, quizzes, and settings—exists solely to set up and track this lock-screen learning experience.

HOW IT WORKS

• Turn on your screen—a Korean word card appears

• Tap to view the meaning, example sentence, synonyms, and antonyms

• Mark "I know it" or "Show me again"—smart repetition does the rest

• Curious to learn more? Tap Ask AI to explore the word via Google Search — nuances, 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 Hangul course teaches you the alphabet itself: every vowel and consonant with mnemonics, syllable building step by step (ㅎ + ㅏ + ㄴ = 한), batch final consonants, and the real pronunciation rules — 합니다 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 there.

SMART REPETITION THAT NEVER FORGETS

The Leitner Method brings back each word just before you're about to forget it: 1 hour → 1 day → 3 days → 7 days → 30 days. Words you know move back; words you miss come back sooner. Your streak and progress statistics keep you motivated.

QUIZ MODE
Turn the card to Quiz and choose the correct meaning from four options. Instant feedback, hints, and a Quiz accuracy statistic to help you beat your score. In the Korean course, the Quiz trains letters: assembling syllables from their parts and matching each letter to its sound.

20,000 TOPIK WORDS
Vocabulary curated from the National Institute of Korean Language's learner word list and the public TOPIK guidelines, covering every level from beginner to advanced (TOPIK 1–6). Each word comes with its transliteration, part of speech, a natural example sentence, and synonyms/antonyms. Browse the full word list, search, and bookmark words for later reference.

MAKE IT YOURS
• Word levels: Korean alphabet basics, beginner, intermediate, or all
• Display frequency: Every time you turn it on, hourly, every 3 hours
• Daily limit for new words keeps repetitions manageable—and reaching it never ends your session
• Quiet hours—no cards at night

• Alarm-safe: The card stays hidden while your alarm is ringing or about to ring

• Swipe up from the bottom of the screen to hide the card, enabling system gestures like Samsung Wallet to work

• Two daily reminders that automatically drop once you've learned

• Card font size, transliteration toggle, "Always show meaning" option

PRIVATE AND COMPLETELY OFFLINE
Everything works 100% offline. No account, no login, and your learning data never leaves your phone.

Note: The app only requests permission to "Show over other apps" to display the flashcard when the screen is turned on. It never covers other apps and never compromises your device's security.

Start today—one word at a time, every time you look at your phone. (The last sentence appears to be a nonsensical string of characters and is omitted.)
