KanjiBox adapts to your performance by prioritizing items you struggle with, and reducing repetition of material you already know. As you progress, it will introduce new kanji and vocabulary, but always while following your pace.

Behind the deceptively simple Multiple Choice Question format, is a well-oiled algorithm designed to trip you up: similar-looking kanji, subtle pronunciation differences, closely-related grammatical words…
Because the goal is to learn the language, not how to beat the test.

始めましょう！Let's get started!
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.
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
Great App for Studying for the JLPT

Great App. Please add kanji sets by grade level too
tsmashace
Really great app. No frills but solid functionality. It allows you to drill kanji, vocab, readings, etc. A nice surprise for me has been the KanjiDraw add-on. Forcing yourself to recall (rather than just recognize) kanji really reinforces the learnings. You’re forced to notice minute details between kanji as well as the actual radicals and components themselves. And the writing hints decrease as you get a kanji repeatedly right.Only thing I wish is that the kanji were also natively grouped by grade level rather than just JLPT level. I would love to be able to learn a set of kanji by each grade level without having to create a custom set. There doesn’t seem to be any shared sets that group them like this either.
Misc fixes and improvements.
