Relaxing. Nice to just space out and color. Lots of templates to choose from, I really like the mystery ones, it would be nice if there was an option to "mystery" any template I wanted. Even tho I'd see the outline at first, it would be fun to be able to remove it and expose the picture as I went. The ads aren't really annoying but sometimes the app would freeze up because it was trying to play an ad mid-coloring, but the ad free version is priced ok
