Words that actually stick. Most language apps are built around streaks, pressure, and guilt. Lengio isn't. It's a calm, beautifully designed visual vocabulary app that works with the way your brain actually remembers — through images, not endless text drills. LEARN THE WAY THAT WORKS FOR YOU Lessons Follow a guided path that builds naturally from the ground up, with mini-exercises after every concept to lock in what you've learned. Word Categories Browse thousands of words organised by topic across 25 languages. Words live across multiple categories so you encounter them in context — the way real fluency is actually built. Quizzes & Flashcards Spaced repetition built right in, so you review each word at exactly the moment you'd otherwise forget it. No wasted time, no drilling words you already know cold. AI Speech Partner Hold the mic and have a real, free-form conversation with an AI tutor in your target language. Gentle, contextual pronunciation feedback as you speak — like having a patient language partner available any time. 221,000+ WORDS. 25 LANGUAGES. From Arabic to Ukrainian, from Japanese to Portuguese — Lengio covers 25 languages with over 221,000 words, every one paired with an image to anchor it in visual memory. Because a word tied to a picture is a word you actually keep. MAKE IT YOURS Replace any stock image with a photo from your own camera roll. Your memories, your associations, your language. The more personal the image, the deeper the word sticks. FREE & PLUS Lengio is free to download. Core lessons, word browsing, flashcards, and daily reviews are included at no cost. Lengio Plus is an optional auto-renewing subscription that unlocks unlimited daily reviews, the AI Speech Partner, all word categories, custom card images, and full Did You Know card access. Payment is charged to your Apple ID at confirmation of purchase. Subscription automatically renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID account settings. No streak guilt. No leaderboards. No cartoon mascot judging your progress. Just a language app you'll actually want to open — every single day. Your next language starts right now. Support: https://lengio.app/support Privacy: https://lengio.app/privacy
