Well, WK will certainly do that with no issue. 
Whether it works for you or not really depends on what kind of learner you are. I’m the type of person where I need a structure early on, or I won’t be able to focus properly. WK gave me that. If I’m being completely honest with myself, probably around level 30-35 or so, I stopped really needing the program. I was doing enough reading on my own that I was learning a lot of things before I came across them in WK, and often enough that by the time it hit in WK, it was reviewing something I didn’t really need to do. I finished it out mostly because the habit of doing it daily was so ingrained, it ultimately didn’t take up too much of my time, and I’m a horrid completionist, often to my own detriment.
If you don’t need the structure that WK provides, and you want to learn more quickly, Anki decks will likely get you there faster, and you can tailor them to what you are actively trying to learn. (Lyrics from songs, etc., etc.), whereas WK doesn’t offer that same kind of flexibility. Ultimately, I still think WK does a great job of instilling kanji, and I definitely credit it for getting me off the ground, so to speak, in learning how to decipher the arcane scribbles that they felt like early on.
I’m not really going to get into the nitty-gritty of the complaints, because I haven’t been following it closely enough (why would I? It’s well past the point where I need to care about that), but ultimately, I would say continue with the free trial. If you like it and think it’s worth your money, then go ahead and invest in it. If you think that maybe you want more freedom in the order of what you want to learn, then use Anki (or similar) instead. 
Regardless of if you decide to stick with the main program or not, I still think the forums themselves are a great resource, separate from the SRS program, and you don’t have to be engaged in the SRS to enjoy the benefits of the community. There are a lot of threads where you can ask grammar and culture questions in; you can join book clubs (linked to the Absolute Beginner Book Club) for reading practice. The community is the strongest part of WK (even if it’s occasionally prone to drama, overreactions, and infighting over updates 
)
