RTK 2 for Hanzi? (how to go about the Hanzi readings)

After studying Japanese for quite a while now, I now started learning Chinese. However I ran into one problem rather quickly, and that's that I have no idea how to go about the Hanzi readings. Whilst I know for a fact that phonetic components, similar to the Japanese ones provided in RTK 2, exist, however I haven't found an equivalent book/website that will teach me the readings based on phonetic primitives or any other meaningful and systematic way.
Are there any resources you could recommend to me? I'm looking for something like WaniKani or RTK 2.
