[Android] Kakumei for WaniKani

This project is a continuation of WaniKani for Android. I wanted to continue using it after V1 API was shut off, so I updated most of the application to use the V2 API.

There are some things I haven’t gotten to yet (including notifications, recent unlocks/critical item display in the dashboard, and support for vacation mode) - however all the functionality I thought important works.

Good work!


When I saw the title, my first thought was “Kumirei for WaniKani”





Just out of curiosity, is there a reason you dropped one mobile app just to make another one with the V2 API key? Not criticizing just curious.

At the very least, it would minimize confusion that “WK for Android” was an official app if it had a different name.

It seems that OP doesn’t believe this to be a new app, but just a new name:


Are you by chance under the impression that the two apps are by the same developer?

I am the author of WK for Android. For a while now, I hadn’t been able to maintain it, and with the new API, decided it was finally time to discontinue. @mrothberg37 figured he’ll pick up the baton and change the name to something good while at it.


Yeah I thought it was woops. Well that makes more sense lol

Thank you! I much prefer the design and simplicity of this over other apps like Flaming Durtles

Was an avid user of the original so will definitely be using this :slight_smile:


It’s fantastic to see this project getting an update, thanks!

Sadly, I can’t upgrade to the new app because of the Android 7 minimum requirement. :slightly_frowning_face:

Any chance this could be made to support Android 6 like the old version did?


Done, released an update with a lower minimum Android version. Thanks for pointing that out, I didn’t realize it was set so recent :sweat_smile:


Much appreciated! Count one more dedicated user. :smiley:


Hi @mrothberg37
Happy to see back this app in the play store! In my case I’m a UX designer and I would like to collaborate with u if possible to make it even better :slight_smile: i find the app is awesome and it would be a pleasure to make it the best! Or at least chat about it.

Anyway, congrats for an amazing work!


Whoops missed your post here, it’s been pretty busy for me with the holidays and all. I did get/reply to your email though!

@mrothberg37 Heya! I’m interested in contributing if I can, though I’ve never done Android dev before (I’m a JavaScript dev). Is there a particular IDE/setup you’d recommend that I could install to help me poke around the project?

@mrothberg37 any chance for updates for unfinished features like notifications?

I started looking at notifications a little bit, and I have a decent understanding of how they used to work. It looks like the app had the ability to set a reminder interval (30, 45, 60…360 minutes), and then whenever the phone would unlock the app would create a notification if the selected time had passed (and there were reviews or lessons waiting).

Is that same functionality what you would want in a notification feature? Do you have any ideas for how you would like notifications to work in general including any specific ways you would like to configure them? I’m open to ideas.

Android Studio is what you would use. I recommend installing it through the JetBrains Toolbox app.

The app stopped working after the recent update :frowning:, which is understandable of course. I wonder if you are going to update it?
