Recommendations for level 60 returner (reset? Etc)

I focus on reading and pick up vocabularies, as well as Kanji, here and there.

You should also know there are some Kanji and a lot of vocabularies not in WaniKani as well.

Either [Web] WaniKani Custom - The WaniKani SRS system but with your custom words and vocabulary or - Web & Apps SRS Study Platform look nice, if you don’t want to use Anki.
