Similarly to @RoseWagsBlue, I use KaniWani as the base of my kanji writing practice. I try to recall the reading (with the correct pitch accent) and write the kanji down on a mini whiteboard. Even if I get the reading correct, if my pitch accent or kanji is wrong I manually fail it.
That being said, this is my second time going through WaniKani and when I tried to do something similar the first time around it was really overwhelming, mostly because I was trying to recall things from memory I had just learned. I would recommend not letting vocab unlock until it’s master or higher in WK to prevent this.
