Nihongo Flow

Read full description

Nihongo Flow teaches you hiragana, katakana and kanji, builds a vocabulary that sticks, and shows you how Japanese sentences work. A few minutes a day is enough. Explanations are in English or German. VOCABULARY THAT STICKS • Your learning path takes you through the most common words: 2,000, 4,000 or more than 5,800, you choose. • Every word comes back just before you would forget it (spaced repetition). • Practice with flashcards, multiple choice or romaji typing, or say the word out loud and Apple speech recognition checks your pronunciation. • The memory heatmap shows which words are solid and which are fading. HIRAGANA, KATAKANA, KANJI • Hiragana and katakana with all basic and voiced characters, plus 40 N5 kanji with on and kun readings. Quizzes and typing drills in rounds of 10. • Handwriting (Premium): write kana and kanji with your finger and get an instant check of stroke count and size. SENTENCES AND GRAMMAR • Grammar from N5 to N1: 52 lessons and a level check for your grammar level. • Sentence Blocks: see how a sentence snaps together from colored blocks, build your own from words you've learned, and stack verb endings from polite to passive. MORE PATHS • Baby Path: picture first, then the word, the way toddlers learn. • Topic Path: nature, seasons, home and more. • Slang & Colloquial: how people in Japan really talk, with the textbook version for comparison. Includes crude expressions, clearly marked. • Business Japanese & Keigo: 463 forms and terms in 29 chapters. • Immersion: short texts on anime, travel, daily life, news and business. Tap a word to add it to your vocabulary. • Hokkaidō Densetsu (Premium): travel across Hokkaidō in 18 stations, with culture cards, Ainu culture, a collector's album and a dice race against rivals. SENSEI: AI FEATURES FOR AGES 16+ • Chat with Sensei in Japanese or English, as a friendly teacher, an anime character or a business mentor. • Voice call with Sensei (Ultra Maxx): you speak, Sensei listens and answers out loud. • Plus "Teacher explains", example sentences, the Sentence Puzzle, an AI check for your sentences, text correction and "Your level today". • AI features use Claude by Anthropic. They are available from age 16, and only after you agree once. You can withdraw consent anytime in Settings, and you can report any AI answer. Everything else works without AI. KEEP GOING Streaks, levels and XP, "What to learn today?", a Japanese proverb every day and your own avatar. No ads. Speak Japanese? Settings > Course also offers a German course with a Japanese interface. WITHOUT A SUBSCRIPTION OR WITH PREMIUM You need an account with email and password. Without a subscription you learn with energy: each answer uses one point, and energy refills over time. AI features have a daily limit. "Nihongo Flow Premium" gives you unlimited energy, all AI features with no daily limit, handwriting practice and Hokkaidō Densetsu. "Nihongo Flow Ultra Maxx" is Premium plus the voice call with Sensei, up to 15 minutes a day.
