Pick a guided lesson, browse word categories, drill with flashcard quizzes, or chat with an AI tutor — all in a clean, distraction-free app that respects your time.


















Some days you want a guided path. Some days you want to drill flashcards on the train. Lengio gives you multiple learning modes — switch any time, your progress stays in sync.
Want to be guided? Follow step-by-step lessons that build on each other, with mini-exercises after every concept. From first hello to comfortable conversation.
Want to explore? Words live in multiple categories at once — "café" appears under Food, Travel, and Daily Life — so you find them where they're useful, not in some random list.
Want to test yourself? Tap-through flashcards and quick multiple-choice quizzes with spaced repetition built in. The hard words come back; the easy ones step out of the way.
Want to talk? Hold the mic and chat with an AI tutor in your target language. It listens, replies, and gently corrects pronunciation — no schedule, no judgement.
Replace any stock image with one from your own camera roll. Personal associations form much stronger neural connections — meaning faster, longer-lasting recall.
No streak guilt, no leaderboards, no cartoon mascots shouting at you. Just a calm, beautiful app you actually want to open — designed in native SwiftUI for instant taps.
Speak out loud, in your target language, with an intelligent AI tutor that listens, responds, and corrects you the way a patient native-speaker friend would. No scripts. No judgement. No waiting for a class to start.
No setup wizards. Open the app, pick a language, and start learning the way that fits how you think.
Choose from 25 languages and download a language pack in seconds. Switch any time — your progress is tracked separately per language.
Open a structured lesson, browse word categories, drill a flashcard quiz, or chat with the AI tutor. Mix and match — every mode shares the same progress.
Short, satisfying sessions designed for real life. No streak guilt, no notifications shouting at you — open the app when you want, close it when you're done.
One word at a time. Clean cards, native audio, and a single tap to make it yours. Nothing extra to learn before you start learning.
