Please by all means say what you think of this idea, all feedback will be taken seriously!
We (limeshift) are currently developing an iOS app that uses the WaniKani API.
At the moment it sources all required data from the WaniKani servers for a user after they enter their API ID, and then stores it locally on a user’s iPhone/iPad for offline use. We have yet to program some of the functionality, but it will hopefully be a really good addition to the WaniKani experience that will be useful for everyone.
The app will be done soon; it will allow you to practise your unlocked radicals, Kanji (both readings and meanings), and vocabulary (both readings and meanings). It will will also notify you through a notification when your next review is.
All iPod Touch and iPhone devices, including the ones with the Retina display, will be fully supported.
All iPad generations will also be supported, including the iPad Mini and iPad 4G.
Done: I have already created all the graphics that the app will use (over 300!)
Done: The user is able to ‘login’ to the app using their public API ID, and their unlocked radicals, Kanji, Vocabulary, as well as their user data such as username, are sourced from the WaniKani servers and stored on the device for offline use.
To do: Make the user able to write the reading/meaning of the vocabulary/radical/Kanji.
To do: Create next-review notifications.
To do: Loads of other stuff that might need to be done.
PLEASE SUGGEST FEATURES YOU’D LIKE TO SEE - WE WANT TO MAKE EVERYONE HAPPY.
Note: I understand that some people disagree with the idea of practising outside of WaniKani. This app will be for those that feel that using it will help them learn Japanese faster, not for those that don’t. It’s all up to personal preference, I think.
It should be available for download in about 2 weeks if all goes well. Stay tuned!

Woo, can’t wait!
That’s awesome!
Doesn’t this sortof undermine the idea behind Wanikani? The WK team was very specific in their implementation that there not be multiple choice. I know from experience with Kanjibox (which you’re probably trying to imitate based on your name) that I can guess the meaning of kanji that I don’t know simply based on eliminating the answers that I know to be false.
sounds interesting, looking forward to giving it a try
Sorry to rain on your parade. I highly doubt the usefulness of any such app.
In my opinion it would only be useful if you could do lessons and reviews, which the
API does not (yet?) provide the means to. If it did, I had build that app a long time ago 
So I am asking myself whats the point of doing a quiz outside of WaniKani SRS? Waste of time maybe?
Also answering a multiple choice question is NOT the same as having to type the answer.
Tricks you into thinking you are better than you are and lessens the learning effect
compared to when you actually remembered the answer after a bit of consideration.
I also doubt you should copy any WaniKani material even if it is just for offline usage?
So basically you provide an app with limited use and connect it with the WaniKani name.
Maybe it’s just to have something out there in case the WaniKani team decides to partner
We might also add functionality so that the user has to type the answer.
I like the idea - being able to practise things you already know is nice without being penalized by the SRS.
One thing that would be even better is to be able to practise your ‘in review’ items again without being penalized for getting incorrect answers.
I’d love to test out your app and give feedback, let me know if you’d like testers.
There is a way to fetch the SRS queue (and therefore do your reviews/lessons from wanikani) but I’m not sure if it could be implemented elegantly and it’s probably just too complicated.
Yeah, multiple choice is way too easy.
Typing is the way to go.

Thank you all for your feedback so far; no more quiz format, and I agree with that. Writing is the way to go.
Please suggest any features you’d find useful so we can start putting together a list of the things my brother has yet to program.

But I'm changing it to simply Wani now, because it sounds better, and also now people can't say we're copying someone, which we're not.

Meh, it isn't an official app, so maybe it's better that you don't?
Yeah, that’s the point, but all sensible name suggestions are welcome.
The whole point of WaniKani is that if you get the item wrong you get it again soon. Practicing defeats the purpose. Unless you can do the actual reviews in this app (which you can’t since the API doesn’t support it yet), this will actually hurt your kanji learning. Even if you didn’t know the item in this app, you do then know it in WaniKani, but you don’t get it again soon. So you’ll never really remember it. This app is fine if you want to learn kanji that way, but don’t link it with WaniKani.
Yeah I guess, but with the app you’ll be able to practise when you’re offline just to help you remember things you may have forgotten. It all depends on the user; for example, they may like the idea of only thinking about a particular item when the review comes up on WaniKani, or maybe they may like to reinforce their knowledge often, even when WaniKani doesn’t give them the review.
I just thought that this app may be useful for some, of course not all, so that’s why we’re making it.
Once you can do reviews through the API then we could add that functionality to it pretty quickly, too, which would make the app much more useful for most people I think.
Can you make this multi-platform, and teach stroke order?
I don’t see the hurt in reviewing stuff you learned two weeks ago.
I’m not sure about the multi-platform idea at the moment (I’m guessing you want Android?), but the stroke order for Kanji could be done.
