About
You glance at your lock screen dozens of times a day. What if every glance taught you a Korean word?
LockVocab - Korean Words turns your lock screen into a Korean flashcard. No need to open an app or set aside study time: the words show up where you already look every day, and they stick.
5,200+ words in three levels (beginner, intermediate, advanced) based on the learner vocabulary list of Korea's National Institute of Korean Language, covering TOPIK beginner to advanced. Every word comes with a meaning and an example sentence with translation, and words of Sino-Korean origin show their Chinese characters (Hanja). The app interface is in Traditional Chinese.
FEATURES
• Lock screen wallpapers
21 paper-style templates (big word, example card, vertical writing, manuscript paper, multi-word lists, side-by-side translation…), 8 traditional color themes and 4 Korean typefaces. Use a built-in background or your own photo. A Shortcuts automation swaps in new words every day.
• Live Activity and Dynamic Island
Keep a word card on your lock screen and in the Dynamic Island. Tap the corner to see the next words without opening the app.
• Your own words
Add words that aren't in the list and put them on your lock screen too.
• Easy shortcut setup
A step-by-step guide gets daily wallpaper updates running in three steps.
• Study and review
Mark words as known or not yet, save favorites and hear the Korean pronunciation. Words you don't know yet become a review list you can also use as a wallpaper source.
PRICING
Free: 100 beginner words, all 1–4 word templates (10 in total), photo backgrounds and up to 20 words of your own. A one-time purchase unlocks every word, the three level lists, the 5–10 word templates and unlimited words of your own. No subscription, no auto-renewal, no ads.
PRIVACY
No account and no personal data. Your study progress and your own words stay on your device, and everything works offline. Only anonymous usage statistics are sent to help improve the app.
