WordBit 英語 (気づかない間に単語力UP)

Learn English vocabulary on your lock screen every time you check your phone—turning idle moments into productive study time. WordBit 英語 (気づかない間に単語力UP) displays new words, example sentences, and pronunciation guidance automatically, so you can absorb more than 1,000 words per month without disrupting your daily routine.

Content tailored to your level keeps learning engaging and relevant. The app includes over 10,000 words spanning beginner through advanced proficiency, organized by CEFR levels (A1 to C1) and specialized categories like IELTS, TOEFL, business conversation, travel phrases, and daily dialogue. Each word comes with real-world example sentences showing how it's actually used, plus additional details such as word origins, irregular verb forms, and phonetic symbols to guide pronunciation.

Quiz and cover modes let you test your retention, while the daily repeat function reinforces words throughout a 24-hour cycle. A word classification feature helps you track which terms you've mastered and remove them from your active list. Search functionality makes it easy to find specific vocabulary, and 16 customizable color themes (including dark mode) reduce eye strain during extended study sessions.

The app also includes comprehensive conversation packs covering practical scenarios—shopping, business meetings, travel, relationships, and famous quotes—so you learn vocabulary in context rather than as isolated terms. Whether you're preparing for an exam, building general fluency, or simply expanding your English range, the lock screen format eliminates the excuse of "not having time to study."

All core content is free, with new material continuously added. The more you share the app with others, the more premium content you unlock, creating a natural incentive to build a learning community around you. WordBit 英語 (気づかない間に単語力UP) transforms your lock screen from a distraction into a language-learning partner that works in the background of your life.
