What's New in KanjiBox

3.2.0

July 28, 2026

New: - Streak rescue: break a long streak by a single missed day and you now get 36 hours to win it back by completing six study goals. - Filter your flashcards by progress: choose which learning groups (new, learning, mastered...) appear in your study deck. - A new "non-standard forms" setting lets handwriting practice accept alternative stroke forms. - The Achievements tile badges unseen unlocks, and newly earned achievements glow until you view them. - More streak milestones, so a long streak keeps changing as it grows. Improved: - Handwriting recognition is far more accurate and now accepts common alternative and rotated stroke forms. - Kana handwriting accepts handakuten circles drawn in either direction, from any starting point. - Breadcrumbs fill the available width on large screens instead of collapsing to "...". - The study settings panel can be swiped away, with the grab handle now on the bottom edge. - Kanji reading headings and the guided tour are fully translated in German, Spanish, and French. - Grammar practice picks questions better matched to the vocabulary you know. Fixed: - Sharing an achievement could restart the app on devices low on memory. - AirDrop sharing failed with "upload failed" while every other share target worked. - Share images rendered at the wrong size and broke the certificate layout on iPhone. - The kana completion certificate was labelled "KANJI". - Mixed date formats could misorder synced study data and reset your streak. - "First studied" dates that showed as 0000-00-00 are repaired. - Opening a study set could crash the app. - The Listening drill ignored the study set you had selected. - Skipped quiz answers were recorded as wrong. - Kana handwriting no longer asks for characters that cannot be told apart when drawn. - The progress ring did not render on older iOS versions. - The right-hand safe area was wrongly reserved in landscape. - A claimed streak rescue was undone on the next app launch. - Deleted study sets were not always removed until the next sync. - Two open tabs could sync at the same time and conflict. - Factory reset now clears saved quiz scores and every in-memory setting.

The best Japanese learning app!

I thought this app had long since been abandoned by the dev but I still found it useful and kept it on my phone since I was also afraid it might disappear someday. The go my surprise it suddenly got an update and got such better and every update now makes it run even better and get even more useful. Thanks dev for not giving up on this one!

Can’t kanji draw my study sets anymore?

I’ve been using this program for many many years. And after a while, I just figured it was abandoned, because it hadn’t been updated in years. But I still continue to use it, with my most favorite feature being able to create my own study sets, then use those study sets in Kanji Draw. So I was excited to see this had been updated recently, and some of the new UI is nice, but it seems now that I no longer have the option to do Kanji draw with my study sets. Honestly, that was the main reason why I used this program. Being able to draw the kanji help me remember them.

I really do hope this feature comes back soon. Also, with the kanji draw the current line stroke when you draw is too thin and sometimes hard to see. I preferred it in the old version where the line strokes were thicker. Also, at least on the iPad, I dislike how the draw window slightly gets smaller once you draw your first stroke. I think it tries to fit in some new text once that first stroke is drawn, and it shifts the whole draw window slightly up and a bit smaller. It can be distracting.

I think if these issues can be resolved, then this will be a perfect program for studying and learning Japanese

Actually really useful!

Great value for money, responsive developer, funny asides, what’s not to like. Used it myself and now using it in a class to teach some Philippino guys. They love it too.

Wonderful tool

I've been using this app on and off for almost a full year now. I picked up the original site back on Facebook when I was I Japan. Amazing tool to practice reading with.

Great App for Studying for the JLPT

I try to do at least one kanji, vocab, and reading quiz per day, and it's motivating to see the progress bar for each advance. The statistics in this app are really good for evaluating how well you know things. I prefer this to Anki for a number of reasons: you aren't punished for being unable to review every day, the multiple-choice format is more honest than self-grading yourself, and this app is really really good at making the multiple-choice answers really REALLY tricky, which makes it extra good practice for the JLPT.

The developer has made a lot of updates recently to better optimize the UI for phones. You can sync your progress so you can have multiple copies of the app on different devices. The developer is also really quick to respond if you find and report a bug.
