What's New in KanjiBox

3.3.3

September 14, 2026

New: - Resetting your learning stats now syncs safely across devices: your other devices notice the reset and ask whether to reset too, keep their data and restore your account, or decide later. Improved: - While that choice is pending, syncing pauses and a clear indicator shows why - no more silent merging of old progress back into a freshly reset account.

too many functions

I think they developers have tried to add a bunch of functions to this application recently however it’s become much more difficult to use effectively. Simple is best! The GUI is very difficult to understand and I feel like i’m making no progress going through tons of options when all I want to do is quiz myself in my free time.

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.
