Holy buckets! I don't know how/where I would use this professionally currently, but personally...wow! As someone with a hereditary double chin and dark circles under the eyes (thanks Sharbonno clan!), the Beauty feature is genius! Overall, its a fun app with plenty of filters, frames, and other fun editing features. If nothing else, a great place to spruce up your social media pics before posting.
The only thing missing is red eye reduction...which is about the only advantage Aviary has.
For both, I could do without the ads and the stamps/stickers.
Also a pretty cool tool, which I would love to use if I did more graphics/marketing for the library. Maybe when I do my Stuffed Animal Sleepover this year, I can make it look like the animals got into paint? I see kids especially getting a kick out of seeing things in different colors than they belong.
