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.

The main problems I have with reviewing a kanji is that if I forget what the kanji looks like and therefore fail, it immediately goes to the step with the green dots where it feels like it's wasting my time. I already know where the start points are, and you either have to do that just to eventually do it without any guide on screen or mark it as "just learned" to skip it to the next day. Maybe it could be a toggle in the settings that it doesn't immediately go back to the one with the green dots,
