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 Kitsun.io - Web & Apps SRS Study Platform look nice, if you don’t want to use Anki.
