There was one in beta testing a few years ago. It went back to the drawing board for a bit of a rework over some fundamental issue with how it communicated with the server, and… I haven’t heard anything since.
Probably because there are plenty of third-party apps that accomplish the same thing and are great at doing it. Kamesame for iOS and Flaming Durtles (I think) for Android. No need to waste time and effort building something like that when you’ve already made you API public.
Yes thanks, that works much better but nothing beats typing on my pc with keyboard And for reviews I really love the Anki mode. On average I have about 200 reviews per day so Anki mode really speeds things up for me.
Tsurukame works when you don’t have an internet connection. It buffers certain things. Wanikani in a mobile browser doesn’t / can’t do that. The main problem for me with Tsurukame is that you can’t change the text size - this is really a problem when you get something wrong and it shows the correct reading in a font smaller than your incorrect reading - I don’t understand that UI choice.
Another thing I don’t like about it is the weird graph that shows how many reviews you have left. I can barely read anything on that graph on my iPhone mini and there’s no way to make it bigger. I also don’t see any way to communicate with the developers.
The main problem with all these third party solutions is that there is no responsibility on behalf of the developers to keep developing the app and pushing out regular updates.
This is the case with basically every third party solution, and even for flaming durtles you have a bunch of bugs and no way to get a hold of the developer.
There are many situations where a person might not have an internet connection and wants to review, or when you want to take advantage of some native app functionality (like perhaps setting push notification reminders to study) for WK that would make the user experience even better.
I hope the hard working devs for WK get around to making a native app one day; I bet they’d be surprised how many people would switch instantly to mobile.
