4English - Learn English

4English is a comprehensive language-learning extension that unites all four English skills in one app. It uses the scientific spaced-repetition method to teach vocabulary, supports 150+ packs (IELTS, TOEIC, TOEFL, idioms, events), and lets you save words and build custom word packs from articles, news, stories, and videos. While you read or listen, you can touch any word to look up its meaning instantly.

Beyond vocabulary, it delivers 1000+ bilingual news articles, 500+ English books, and 10,000+ videos with subtitles for listening and reading practice. It includes English grammar explanations (12 tenses) and a variety of exercises—listen and fill, complete phrases, dictation, and shadowing—plus an English Word Chain game to reinforce memory. In short, 4English is an all-in-one solution to practice speaking, listening, reading, and writing efficiently.
