Booklex: Read & Learn Languages

Stuck at B1-B2? Your vocabulary stops growing because your brain skips unknown words when context is enough. Booklex fixes this: → Read EPUB/PDF books in any language → Tap any word - instant translation, no app switching → Words save to your dictionary automatically → Review with flashcards, quizzes and tests → Fully offline. 50 languages supported. I'm an iOS developer who built this while learning Spanish. Read books you enjoy, learn words in context, grow your vocabulary naturally.
