There are a lot of Kanji I haven't seen for a while, guessing they are all at sensei level. Would like to be able to see them to verify I recall what they are. 

This is probably a moonshot, but imagine this: I am studying 200 kanji. I want to practice reading those kanji. Ringotan knows what kanji I am studying and maybe connects to a db somewhere that stores all the vocab for various books. It then recommends books that use kanji only up to the point I have studied kanji.

Conversely, we could select books we want to be able to read, and ringotan would make a custom review of all the kanji therein that we need to know.

Hi, Is there a way to practice hiragana and katana with dakuten (and handakuten). Sometimes, it is easy to learn having some writing experience. Thank for the awesome and practical app!

Please consider adding a Sort by Last Failed search option. This would be very useful to me and probably many other people to be able to grind the Kanjis we struggled with.

For now I'm using the "Most Difficult First" which is also useful, but in some sessions/some cases, Sort by Last Failed would be even more useful. (Both are very useful in different situations)

Thanks in advance! Your app has been of a great help to me so far, I'm grinding my kanji writing skills as this is required for the language school I will be joining in April

I suggest making an account system, a simple one to log-in via e-mail and pass.

Since ringotan will become paid figure something out so only one free account per ip for example or something and so on.. This will help save progress if a device is lost.

I'd love to have a kanji radicals deck to include in my learning.

I'd make it so much easier and faster for me to memorise more complex kanji (Heisig style ;) ).

I passed N3 years ago, and now coming back to relearn kanji, I found out I'm much better at relearning kanji I had the radicals memorised for the first time.

Right now, the app displays example compounds entirely in hiragana. For example, if I’m learning 緯, it shows けいい (details) and いど (latitude).

I think it would be much more useful if the compounds were written in kanji while omitting the character being studied. For example:

• Instead of けいい, display 経?
• Instead of いど, display ?度

This way, we can see how the kanji is actually used in real words rather than just memorizing the hiragana reading. Furigana could also be included on top for reading support.

Here is a sample image of what this (could) look like, though there's

It would be neat if there was a way to sync your kanji progress with MaruMori's API, similar to how you can sync it with WaniKani currently.

This would be especially useful for all the N1-and-beyond kanji that WaniKani doesn't cover.

Sometimes I want to listen to music while doing my reviews, but as soon as I open the app, the audio stops. It'd be nice to fix this, or if it's intended to work this way, add an option to do that.
