Grow Fluency — Learn Languages Through Immersion Most language apps teach you words in isolation. Grow Fluency puts them in context — where they actually stick. Read a story. Watch a YouTube video. Import an article you actually care about. Tap any word you don't recognize to see its translation instantly. Save it, and Grow Fluency brings it back at the right moment using spaced repetition — so you review words just before you'd forget them. It's the same simple loop everywhere: encounter a word in something real, tap it, keep it. Read Short stories generated around your own vocabulary, at your level. Tap any word for an instant translation. Watch Paste any YouTube link and watch with your target language's subtitles live in the app. Miss something? Hit translate-back — the video freezes, you hear the last few seconds explained in your native language, then it replays them in the original. Tap any word in the subtitles to save it straight to your collection. Import Bring in articles from the web by pasting a link, or drop in your own text. Read anything you want with tap-to-translate on every word. Practice Output Practice turns recognition into real production — write a journal entry using the words you've learned and get it corrected line by line. Review Smart spaced repetition schedules every saved word automatically. Track streaks, watch your words move from "learning" to "mastered." Also included: 12 languages, including Egyptian Arabic, Lebanese Arabic, Mandarin, Japanese, and Korean A tutor for any language question, any time Anki deck import — bring your existing decks with you Progress tracking and achievements Learning a language doesn't have to mean grinding through flashcard decks. Grow Fluency turns the things you'd already read and watch into the lesson. Start reading. Start watching. Start learning. Grow Fluency Pro is an auto-renewing subscription, available monthly ($6.99/month) or annually ($59.99/year). Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your device's Account Settings.
