Lexio: Vocab Builder & IELTS

📚 Learn English vocabulary the smart way with Lexio — the vocabulary builder for IELTS, TOEFL, GRE, and serious language learners. Lexio helps you build and retain English vocabulary through word families — groups of related word forms that share the same root. Instead of memorizing "analyze," "analysis," and "analytical" as three separate cards, Lexio groups them into one smart card so you learn the full picture at once. It's a proven method for deeper, lasting retention — perfect for academic English and exam prep. ✍️ CREATE YOUR WORD FAMILIES Build personalized vocabulary sets with terms, definitions, examples, collocations, and word types. Add multiple parts of speech for each root word and see all related forms in one grouped card — the smarter way to grow your English vocabulary for IELTS, TOEFL, and GRE. 🧠 THREE POWERFUL STUDY MODES 🔀 Flashcards Flip through your word families at your own pace. Swipe to navigate and review terms with smooth, intuitive gestures. Tap to reveal definitions, examples, and related word forms progressively. 📈 Learn (Adaptive) Go beyond simple memorization. Lexio generates varied question types from your word family data — multiple choice, fill in the blank, word type matching, example matching, and typing exercises. Adaptive rounds test not just the term, but its collocations and related forms too. ⏱️ Test Challenge yourself with customizable tests. Choose from six question types: multiple choice, true/false, written, fill in the blank, word type, and example matching.
