Yes. Use WaniKani for Kanji.
Use the vocab to reinforce/learn other readings of the kanji. Dont bother with the context sentences until later.
The strength of WK (imo) is that it relieves you of any planning to learning Kanji. You just turn it on and do what is in front of you.
If youre completely new to Japanese, I would say start with Tae Kim’s guide. You will find the Kanji you learn on WK will quickly be put to use. The order of content in TK’s guide is different from most traditional text but it will be more beneficial unless youre studying for a specific short term situation.
You can use this guide to better understand the mechanisms of WK:

Personally I would recommend going as fast as possible for at least the first 5-10 levels to get you a base for doing other things.
