Finishing RTK here, I have already started to learn some vocabulary. However, I realise that if I remember the meaning and the reading, I do not always remember the kanji.
I know Kanji tree does that, but the application does not seem maintained anymore and I had several issues when using my own vocabulary set. Moreover, the writing feature is way less convenient than the one of Kanji study.
Speaking of Kanji study, the writing feature is almost perfect, but sadly does not integrate a feature to write words.
Apart from writing the kanjis, I wonder if there are applications/or decks (Anki, [kitsun.io](https://kitsun.io)) that quizzes the kanjis of a word?
The sense “English -> Japanese” can do that. But this would require to duplicate cards in case the word is known but not the writing or vice-versa.
