About this app

BudoBudo — Japanese Study

BudoBudo brings together everything you need to learn Japanese in one place — no switching between apps, no subscriptions, no ads.

Flashcards reimagined
Import your Anki decks (.apkg) or use the built-in Genki I vocabulary. Cards adapt to what you actually need: new words show you the answer first, due cards come back at the right time, and mistakes get flagged for review. The SRS engine runs fully offline.

Kanji writing practice
Learn stroke order for 700+ kanji (N5–N2) with guided animations and ML-powered handwriting recognition. Draw the character, get instant feedback.

Conjugation trainer
Drill verb and adjective forms — present, past, て-form, negative, potential, and more. Plain and polite forms. Covers all Genki I grammar patterns.

Reading mode
Japanese folk tales (N5–N4 level) with furigana, tap-to-translate, and sentence-level translations. Swipe to look up individual words. Paragraphs are broken by meaning, not line count.

Kana trainer
Hiragana and katakana with romaji, direction switching, and row-by-row practice.

Daily path
Three tasks per day chosen from your weak areas — kanji reading, writing, conjugation, or flashcard review. Progress bar updates in real time.

Everything offline
No internet required. All data stays on your device.

What’s new

BudoBudo now speaks Russian, Spanish, Chinese, and Korean! Switch in Settings — the entire app, all reading stories, and the full Genki I course are translated. Also: smoother layouts, better contrast, and small bug fixes. Found something odd? Let us know via Settings → Feedback!
