I’m also trying to write kanji as I learn them. I start off with a few scripts to learn the stroke order. One pops up when I hover over the kanji, and the second one gives a stroke by stroke diagram order.
WaniKani Unobtrusive Stroke Order
WaniKani Stroke Order
After that I use Skritter, uploaded all the kanji from WK. It really drills me on correct stroke order and such. IMO, it’s a little overpriced, but Kanji Study might be free.
