Earlier I was looking for a WaniKani-like platform for Hanzi. And I'm pleased to say, there is one. It's called Hanzi Hero. Pretty much just like WaniKani down to the pricing and features. Even has a learning track for both simplified and traditional characters, depending on which one's you think you'll encounter.
And for people who care, their site seems to have no tracking, which is great. Can't imagine a for profit site with a free tier also having no tracking, but that's how it appears! Anyhow, I'll use it for a couple weeks and report back:
