Alright, what's a good Android app for letting my brain chill out with some coloring pages, but like, not in a super childish way?

Okay, so I've been trying to find ways to de-stress that don't involve staring at spreadsheets all day. A friend suggested coloring, and I was skeptical, but figured I'd give it a shot. I found Family Love Coloring Book, and honestly, it's surprisingly good. The selection of images isn't just, like, basic cartoons. There are some more intricate designs that are statistically satisfying to fill in. Plus, the color choices aren't awful. You can actually create something that doesn't look like a preschooler's art project. It’s not going to replace my data visualizations, but it's a decent way to unwind after wrangling clean datasets all day. And hey, if it helps with focus, that's a win in my book.
