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.

What’s New

Version 4.31

A few fixes for some... idiosyncrasies that crept last week's update:

- Tile view blank on start up in under certain conditions.
- Unable delete decks.
- Save to deck sometimes wouldn’t save.
- Touching stickies on the study screen could cause a crash.
- Deck list not always updated.
- Other minor changes (thanks AD).

Best vocab/kanji app on the App Store

This app is hands down the best kanji/vocabulary app on the App Store. Has more features than a Swiss Army knife.

One thing I wish tho is if it had (maybe as an add on IAP) more example sentences using the vocabulary words and kanji, that
way you could learn grammar too.

I also wish there was the option for the English translation of the example sentences to be turned off... maybe by tap to show?

Otherwise tho this app is the best... I am still discovering awesome features like the news section which takes current news headlines in Japanese and gives furigana and dictionary definitions for each word.

If you only purchase one app for learning Japanese from the App Store, make it this one.

Update: The developer is very active and helpful if you have any questions or need any help.... I had a problem where I accidentally deleted the JLPT Vocab N4 deck the app came with and he promptly emailed me back and told me that the “restore to original” button in settings will restore the deck back. Kudos to the developer for excellent customer service. :)

Best app for kanji learning on phone

This app will take you from no kanji to however far you are willing to go. I love that I can import my own lists, drill components and browse cards quickly by stack and list type.

In my case, am relaying on stories to remember the kanji (Heisig RTK). The components drill downs help me tie it all out. And import allows you to bring your stories if you have them already (I took an Anki deck with stories, exported it and imported the kanji and stories into this app).

Also love that I can have a screen full of Flashcards (makes them more tangible). For Kanji learning on phone this is the best app I’ve found.

Killer features and great developer

I’ve tried at least a dozen apps to complement my formal and informal Japanese studies, and this stands out for its efficiency at studying both how to read and how to write. The writing practice and stroke order visualization in particular really demonstrate a lot of craftsmanship. This and Quizlet win home screen slots for me.

The developer, Justin, is also great. He responds to suggestions, continuously improves the app (that I gather he still uses himself), and is really responsive if you encounter a bug. I pointed out a glitch in recent update and a fix was on the store in a day!
