Full description
Learn English words naturally by seeing them again and again. Lockscreen English Word Alarm helps you review vocabulary on your lock screen, save words from photos, and test your memory with quizzes. Learn with images, pronunciation, and example sentences to understand each word and how it's used. ✔ Review Words Every Time You Check Your Phone See English words on your lock screen whenever you check your phone. Even without a dedicated study session, you can keep reviewing vocabulary throughout the day. ✔ Build Your Own Word Lists from Photos No need to type vocabulary words one by one. Take a photo or choose an image from your gallery, and the app recognizes multiple English words. Select the words you need, add them to your own word list, and review them anytime. ✔ Remember Words with Images Learn each word with multiple related images. Connect words with images instead of memorizing definitions alone, making them easier to remember and recall. ✔ Learn Meaning and Usage with Examples See how words are actually used in sentences. Study with images, pronunciation, meanings, and example sentences to better understand each word. Dictionary meanings are available in 23 languages. ✔ Word Lists for Different Levels and Goals Choose from vocabulary lists for beginners, school-level English, SAT, TOEIC, TOEFL, civil service exams, and more. Pick the word list that matches your level and goal. ✔ Focus on the Words That Matter Save important or difficult words to Favorites so you can easily find and review them again. ✔ If You Can't Hear the Pronunciation 1. Install "Google TTS" from Google Play. 2. Go to Settings → Language & Input → Text-to-Speech (TTS). 3. Set Google TTS as the preferred engine. 4. Open the Google TTS settings. 5. Go to Install Voice Data and install the English voice data. 6. Make sure your phone's media volume is turned up. If you still can't hear the pronunciation, try deleting the English voice data and installing it again. ✔ Why We Request These App Permissions - READ_PHONE_STATE: Used to pause the app so it doesn't interfere with phone calls.
