Not sure if this is exactly what you’re looking for, but there are iKnow decks sorted by WK level. Or just the normal iKnow decks, but those get a bit frustrating because they introduce words by frequency and if you’re just beginning in WK there are a lot of kanji that you don’t know that makes it very very very frustrating to keep up with (at least in my experience). That being said, I am using the normal iKnow decks.
