Read full description

Learn Japanese vocabulary the way it's really spoken. Watch native speakers say each word in short video clips, then let AI break every sentence down word by word. Tango takes you from hiragana and katakana all the way to JLPT N1: 13,000 words, spaced-repetition (SRS) reviews that schedule themselves, and no account or sign-up. Works on iPhone and iPad. Please note: Tango is made for learners who read Traditional Chinese. Word meanings and AI explanations are shown in Traditional Chinese; the app's menus can switch between Chinese and English. WHY TANGO • Real-video example sentences: hand-picked YouTube clips of native speakers using the word, played right inside the card. Hear the real tone and speed. New clips are added all the time, including a Travel section. • AI word-by-word breakdown: real sentences split into chunks, each with a short meaning and particles marked with a purple line. Tap any word for pronunciation tips and the original audio, plus the grammar point and why it's said that way, like a tutor taking the sentence apart for you. • One-tap switch between "Sentence" and "Word by word": try the full sentence first, break it down when you get stuck. • 13,000 words from N5 to N1: grouped by JLPT level and 25 themes, with kana, romaji and audio. • Smart SRS review: spaced repetition schedules what to review today. Choose to review first or learn new words, and set daily new words to 0 whenever you need a break. • JLPT practice: original practice questions, full mock tests, everyday usage and penguin chat scenes. • Home-screen widget: study one card without opening the app. • No sign-up. The app itself shows no ads (YouTube clips may show ads and need a connection); words and reviews work offline. FOR EVERY LEVEL - Beginners: start from kana and N5, every word with audio and examples - N4-N3: turn "I can read it" into "I can hear it" with real speech - N2-N1: AI breaks down long sentences, keigo and subtle nuance FREE AND PRO Free forever: all words, real-video example clips, audio and reviews; N5/N4 grammar and N5 JLPT practice; 3 full AI breakdowns and 3 full card backs every day. Pro: an AI breakdown for every sentence, full N3-N1 grammar, N4-N1 JLPT questions and full mock tests, everyday usage and penguin chats, unlimited shadowing. Choose a one-time lifetime unlock, or a monthly or yearly subscription (the yearly plan includes a 7-day free trial for first-time subscribers). Subscriptions renew automatically and can be cancelled anytime in your App Store account settings; cancel at least 24 hours before the end of the current period to avoid renewal. Start with 15 words a day and understand real Japanese.
