The pictures are lovely and I enjoy coloring them, but like a lot of users pointed out, there are just so many ads that you have to sit through just to color one image. It's very frustrating when you're coloring, listening to your favorite podcast, and suddenly you get your ears blasted yet again by whatever mobile game ad they're cycling through at that particular moment. Lately though, the app has been crashing a lot. I'll open a picture, it'll start to load, then the app crashes. Weird.
