Currently Anki for flashcards, Tobira for grammar and miscellaneous other practice, the Tadoku graded readers for reading practice and the Japanese with Shun podcast for listening (my listening comprehension is behind).

Anki certainly has a learning curve, but it can’t be beat for content and flexibility. However, I have a background in web design, which really helps a lot with making the most of it. My Anki workflow is rather customized at this point.
