LockVocab - Lock Screen Words
TOEIC & IELTS word wallpaper
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Check your phone, learn a word. Now with your own words too: snap a textbook page or an English article and AI turns it into a word list for your Lock Screen.
You wake your phone 80 times a day. What if each one taught you a word?
LockVocab turns your Lock Screen into a vocabulary card you cannot miss. No app to open, no time to set aside — the word is simply there, where you already look. See it enough times and it sticks.
Built for exams and for work: 5,200 words — 1,500 TOEIC core, 1,400 business English, 1,000 everyday English and 1,300 IELTS/TOEFL academic vocabulary. The TOEIC, business and academic lists are calibrated against published exam-corpus frequency lists, and every word comes with phonetics, a plain-English definition, synonyms, word origin and a natural example sentence.
WHAT YOU GET
• Vocabulary on your Lock Screen
21 paper-style templates (single word, example card, vertical, manuscript grid, multi-word lists, side-by-side translations and more), 8 accent colors and 4 typefaces, mixed however you like, on a built-in background or your own photo. A Shortcut swaps in fresh words on a schedule you choose.
• Live Activity and Dynamic Island
Turn on Live Activity and a word card stays on your Lock Screen and in the Dynamic Island, like a widget — tap the corner for the next batch, without opening the app.
• Add your own words
Missing a word? Type it in and AI fills in the part of speech, pronunciation, meaning and an example sentence, and you can edit anything it writes. Words already in the library use the built-in entry.
• Import from photos
Snap a vocabulary page from your textbook or an English article. AI turns the whole page into a word list; check the ones you want and import them in one go. From articles it picks the words worth learning and uses the article's own sentences as examples.
• One-tap setup
Add the ready-made Shortcut in a single tap, then follow the step-by-step guide, as pictures or as a short video, if you also want the wallpaper to change itself every day. Switch to the Shortcuts app mid-video and it keeps playing in Picture in Picture.
• Learn and review
Mark each card "got it" or "not yet", save favorites, tap to hear the pronunciation. Everything you missed collects into a review list you can also use as your wallpaper source.
• Choose what you study
Pick your source: all words, favorites, words you missed, your own words (My picks), TOEIC core, business English, everyday English, or IELTS/TOEFL. The wallpaper and the Live Activity can each use a different one.
ABOUT PAYING
The first 100 words, every template that shows 1–4 words (10 in all), photo backgrounds and up to 20 words of your own are free, and you can try photo import 3 times. A single purchase unlocks every word, the topic word lists, the 5–10 word templates and photo import, with no limit on your own words (AI fill-in has daily and monthly usage caps). No subscription, no auto-renewal, no ads.
PRIVACY
No account, no personal data, no ad tracking. Your progress and your own words stay on your device. Only if you allow AI word fill-in does the app send the English words and the text recognized in your photo (never the photo itself) through our server to Anthropic's AI model (Claude). Nothing is used to train AI, Anthropic deletes it within 30 days, and you can turn it off anytime in Settings. Everything works offline except the setup videos and AI fill-in. The app sends only anonymous usage statistics, with no personal data, to help improve it.
Wake your phone. Learn a word.
