LinguaDuck: Learn & Level Up You've tried to learn a language before. You downloaded the app, kept a streak for a week, and quietly gave up. Not this time. In LinguaDuck, every word you learn makes your duck hero stronger, and suddenly studying is the most fun part of your day. NEW: WORD DROPS A splashy little game for your first words. Listen to a word, then drag the drop with the right picture into the pond. No reading, no typing: just sound, picture and that satisfying splash. Easy words come first, and it works in 15+ languages. Perfect for a minute on the bus. UNDERSTAND ANIME WITHOUT SUBTITLES Imagine watching your favourite anime and catching every word. LinguaDuck teaches Japanese through 439 real clips from famous anime. After each scene, every phrase is unpacked: what each word means, why it's said this way, and the grammar behind it. You don't just memorize Japanese. You finally get it. READ KANJI LIKE A NATIVE Kanji feel impossible until you learn them one at a time. Trace each stroke, recall its meaning and reading, and watch the reading hints disappear as you master each character. Then open a real manga and read it yourself. HEAR HOW PEOPLE REALLY TALK Textbook phrases won't help you in a Stockholm cafe. Short clips of real native speakers in Swedish, French, Italian, Portuguese and Welsh show you the language as it's actually spoken. YOUR WORDS ARE YOUR WEAPONS Every lesson earns XP, gold and gear. Dive into dungeons where your vocabulary slashes monsters. Explore a pixel world that grows with your course. Furnish your own manor, collect treasures, hatch pets. The more you learn, the stronger you get. NEVER FORGET A WORD AGAIN Spaced repetition brings back each word right before you'd forget it. Courses from A1 to C2. 2 MINUTES IS ENOUGH No guilt. No pressure. No shrill notifications. Play a quick round of Word Drops, pick a 3-minute session on the bus or a 15-minute one at night, and your progress is always saved. Prefer pure study? Turn game rewards off. MADE FOR EVERYONE Dyslexia-friendly font, high-contrast themes, VoiceOver, large text, reduced motion. Works fully offline: on a plane, in the subway, anywhere. BONUS: CHAT WITH CHARACTERS Practise real conversations with friendly story characters. Scripted dialogues work offline; optional smart replies use an AI service key you add yourself. Not available in all regions. A week from now you could be reading your first kanji and understanding your first anime line. Your duck is waiting. Start your adventure today.
