Only for iPhone

iPhone
Build Japanese that sticks with a personalized first lesson, practical phrases, smooth flashcard review, and clear progress across kana, kanji, and vocabulary.
Japanese flashcards are easy to start. Remembering what you studied is the hard part. Inku turns short study sessions into Japanese that sticks. Learn a small set, review it before it fades, and return when the cards are due. Japanese spaced repetition stays simple: difficult words return sooner, familiar words less often, and you always know what to study next.
Building beginner Japanese vocabulary and trying to learn hiragana? Preparing for JLPT N5, JLPT N3, or JLPT N2? Returning to Japanese after a break? Inku connects each stage: kana practice becomes reading practice, new vocabulary becomes Japanese flashcards, and every review moves your study forward.
As your Japanese vocabulary grows, Kanji stops feeling like a wall of disconnected characters. Learn Kanji in context through readings, meanings, memory cues where helpful, sample words, and related vocabulary. Guided lessons cover 400+ Kanji across N5-N3, then move each character into the same flashcard review as your Japanese study. Furigana reading support connects Kanji to kana, pronunciation audio lets you hear each word, and Japanese romaji reading support gives beginners another bridge. As readings become familiar, you rely less on hints and more on memory.
When you find a useful word in class, manga, or daily life, keep it. Build custom decks from Inku's library, or create original Japanese flashcards with meanings, romaji, explanations, and personal notes. Each card returns alongside your review. Whether you are studying Japanese for JLPT vocabulary or saving a Japanese phrase from a conversation, the same system keeps Japanese vocabulary study connected to the language you encounter.
From your first hiragana to JLPT vocabulary, Inku gives you one place to build a strong Japanese foundation:
• All 92 core hiragana and katakana characters
• 2,000+ Japanese words and phrases
• JLPT vocabulary across N5, N4, N3, N2, and N1
• 400+ Kanji through focused lessons and review
• Japanese pronunciation audio for words and phrases
• Furigana, kana, and romaji reading support
• Custom flashcards and decks
• Spaced review, mastery, and study progress
There are no ads, no account to create, and no endless feed. Your progress stays on your iPhone. Open Inku, study the next useful cards, and keep your Japanese practice moving.
