Lockademy កូរ៉េលើអេក្រង់ចាក់សោ

Turn every screen time into a Korean lesson. Lockademy displays a Korean word every time you turn on your phone — read, remember, and swipe. No apps to open, no time to prepare: the time you spend unlocking your phone is already spent learning dozens of mini lessons a day.

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

How it works
• Turn on your screen — a Korean word card appears
• Tap to see the meaning, example sentences, synonyms, and antonyms
• Mark "I know this word" or "Show again" — smart repetition will handle the rest
• Want to know more? Tap Ask AI to search for that word on Google — for deeper meaning, cultural context, and related expressions
• Unlock as usual. This card never blocks your PIN, pattern, or fingerprint

Don't know how to read Hangul? Start from scratch
Don't know how to read Korean? The included 한글 course teaches you the alphabet itself: every vowel and consonant, along with memory tricks, step-by-step syllable combinations (ㅎ + ㅏ + ㄴ = 한), closed consonants (batchim), and real pronunciation rules — 합니다 is pronounced "hamnida," and the cards show you why. Select "I don't know how to read Hangul yet" when you first open the app, and it'll start right there.

Smart review that never forgets
Repetition with Leitner intervals brings each word back the moment you forgot it: 1 hour → 1 day → 3 days → 7 days → 30 days. Words you know move backward; words you get wrong move forward faster. Consecutive days and your progress statistics help keep you motivated.

Quiz mode
Flip the card to Quiz and choose the correct meaning from four options. Instant feedback, hints, and quiz accuracy statistics help you win. On the 한글 course, practice quiz questions: Combine syllables from their parts and match each letter to its sound.

20,000 TOPIK words
Vocabulary selected from the National Institute of Korean Language's learner's word list and public TOPIK guidelines, covering all levels from beginner to advanced (TOPIK 1–6). Each word comes with a Latin script, word type, natural example sentences, and synonyms/antonyms. Explore the entire word list, search, and favorite words for future reference.

Make it yours
• Word level: Basic Korean, Beginner, Intermediate, or All
• Display frequency: Every time you turn on your screen, Every hour, Every 3 hours
• Daily new word limit keeps your learning under control — and reaching it never ends your learning session
• Quiet hours — no cards at night
• Security with alarm clock: Cards stay away when your alarm is ringing or about to ring
• Swipe up from the bottom to hide cards so that system gestures like Samsung Wallet can work
• Double daily reminders that automatically skip when you're done learning
• Card font size, Latin alphabet toggle, Always show meaning option

Fully private and offline
Everything works 100% offline. No accounts, no registrations, and your learning data never leaves your phone.

Note: This app requests the "Show over other apps" permission only to display learning cards when the screen is on. It never overlays other apps, and it never compromises the security of your device.

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