I'm Justin. I moved to Japan in 2002 and I'm married to my Japanese wife (lovingly called "Spellchecker"). I've taken the JLPT tests up to N1 (yes, I was there) using this app. I speak, read and write Japanese fluently and I'm an overactive developer who can't sit still.

Customer Reviews

Memory whiz

If your studying vocabulary and kanji for the Japanese language proficiency tests, to finish all the joyo kanji or to learn more words this is the best flash card app you can buy.

Don't waste your time with amateur flash cards on gFlash or other apps. This one scientifically reviews wrong answers to help you remember.

Interface is great, look is professional. Wish it could do more than just Japanese.

Awesome App but need some tweaks

P. Côté

I stumbled upon this awesome app but it need some tweaks.

For example, the landscape mode seems to have some problems especially after getting out of editing mode or when launching the app. It often go back to portrait mode and then turn back to landscape, which is a bit annoying. Also, when studying, the answer buttons are not repositioned in landscape mode so the text is written vertically. Maybe use icon instead ?

Another killer feature is to be able to create your own study board but the problem is you probably want to use the existing material, which doesn't seem possible right now. As an example, I use the excellent Japanese app on iPhone and you can create your own list of any damn thing (particles, verbs, adjectives, name it) and make your own study set out of this.

It would be awesome if you could create a custom board out of existing material because when encountering new words in life, it doesn't really fit the "academic" order and you might want to study that right away, which is downright impossible right now.

JPLT Grades are also pretty daunting if you just begun learning Japanese. It would be really good if you could start with school grades instead, like the iKanji Touch app.

The very best thing would be to have a writing practice feature to learn how to correctly draw the kanjis since it's the real way the kanjis will stay in your head.

Fix those and you will have a killer app! :)

Good job!

Useful app, but a bit buggy

Dominique Brodeur

I bought this app so I can learn Kanjis when I commute to and from work. It does the job, and I'm happy with it. The interface is nice and clean, easy to read. The colour system is pleasing to the eye and informative. As Philippe has reported, the app is buggy. It has "quit unexpectedly" a few times on my iPod Touch (4th G, 64gb), especially right after the installation. But it has become stable over time, enough to let me use it and enjoy it. That said, I now refrain from using the "Browse" function that gives an overview of all the cards of a particular section, because that will cause the app to crash. (Can you please fix that Justin?) -- In a future release, I would really like this app to be expanded to include separate chapters on "verbs", "nouns", "adjectives" and "particles", as well as a writing practice section.
