Our verdict on Kanji Dojo
Kanji Dojo is an open-source application for learning Japanese writing and vocabulary. It supports hiragana, katakana, and more than 6,000 kanji, making it suitable for beginners building character foundations as well as learners following JLPT levels, school grades, or custom study lists. Its scope also includes readings, meanings, vocabulary examples, flashcards, dictionary search, and reading practice, so it can support more than isolated handwriting drills. Offline use and access across web, Windows, macOS, Linux, Android, and an iOS test version broaden its fit for learners who study across devices.
The strongest feature set is the combination of writing practice and review structure. Stroke-order exercises give character study a pen-control component, while spaced-repetition reviews, custom decks, and vocabulary lists let learners shape practice around a particular level or goal. Dictionary search and vocabulary flashcards connect individual characters with practical reading material. This breadth makes Kanji Dojo more suitable for a structured Japanese study routine than a narrowly focused kana trainer, especially for learners who want to combine handwriting, recognition, and vocabulary work in one application.
Platform coverage is a clear advantage, but iOS access is less settled than the other listed platforms: the current TestFlight page is not accepting new testers. The repository was archived on August 27, 2026, while official app listings show 2026 updates, creating an important distinction between repository status and app availability. Pricing is also presented differently across product listings, so buyers should review the current terms before expecting paid extras or fully locked-free access. Choose Kanji Dojo for broad, offline Japanese practice with an open-source foundation; choose another app if immediate iOS onboarding or a clearly defined paid-plan structure is essential.
