Learn real languages through real sentences. Not random words. Not boring drills. Lingden teaches Norwegian, Spanish, French, German, Italian, Russian and 7 more languages the way they're actually spoken - one real sentence at a time, with word-by-word meaning, native audio, and proven spaced-repetition that locks vocabulary into long-term memory. Understand a language. Don't memorize it. LEARN 12 LANGUAGES Norwegian, Spanish, French, German, Italian, Portuguese, Dutch, Danish, Swedish, Turkish, Russian, Greek. CEFR levels A1 to B2 - from your very first word to confident conversation. SCAN A BOOK INTO FLASHCARDS Point your camera at any page - a novel, a menu, a sign at the station - and Lingden turns the sentences you pick into full flashcards. Your iPhone reads the page itself using Apple Vision; the photo is never uploaded, and only the sentences you choose ever leave your device. Works for every language except Greek, which is still to come. EVERY FLASHCARD IS A MICRO-LESSON Tap any word to hear it. See the IPA pronunciation. Read the dictionary meaning. Listen to the full sentence in a native voice. Lingden treats every flashcard like an annotated textbook page, so you don't just memorize vocabulary, you understand how a sentence is built. SPACED REPETITION THAT WORKS A five-box review system based on proven spaced-repetition research. Words you struggle with come back sooner; words you've mastered move further out. Just 10 to 20 minutes a day and your review queue keeps shrinking while your vocabulary keeps growing. NATIVE-SPEAKER AUDIO ON EVERY WORD High-quality voices for every supported language. Hear correct pronunciation for every word and every full sentence. Build your ear before you ever speak. 6,700+ VERB CONJUGATIONS Master verbs across 7 tenses: present, past, future, perfect, imperfect, conditional, imperative. Every conjugation arrives as a real example sentence with audio. Finally understand why Spanish has so many verb endings and why French verbs surprise you. CREATE YOUR OWN CARDS WITH AI Pro users paste any word or phrase and Lingden generates a complete flashcard: a real example sentence at your level, word-by-word breakdown, IPA, meaning, and native audio. Build a deck from this morning's article, your favorite song lyrics, or the words your language partner taught you yesterday. TOPIC AND LEVEL FILTERS Focus on travel vocabulary before a trip. Drill medical terms before an appointment. Lock to A1 basics or push into B2 nuance. Your study plan, your way. VOCABULARY BROWSER Browse every word you've ever learned. Search, filter, sort by mastery, and see your progress as a real, growing personal dictionary. FREE FOREVER 1 language, 10 new cards per day, full A1 to B2 access, spaced repetition, word-by-word breakdowns, audio and IPA. No ads, no time limits, no trial countdown. LINGDEN PRO Unlock unlimited languages, 50 new cards per day, scan-a-book, AI card generation, verb conjugations, topic filters, and the full vocabulary browser. Monthly or yearly subscription - the yearly plan is the best value. Cancel anytime in iOS Settings. PRIVACY FIRST We never sell your data. We never track you across the web.
