I’m also using those three resources, at least if we’re just talking SRS’s. I try to listen to podcasts, watch Japanese youtubers and read any random texts I can such as song lyrics and stuff I come across online but I have no routine for that unlike with Wanikani, Bunpro and Iknow.
Btw, are you aware of this? I find it ties Wanikani and Iknow together such that they both reinforce each other.
