It's a lot of fun. If you're a fan of the watercolor look you can get some interesting effects. It's strongest suit is that it's not afraid to leave whites on certain settings. It does a little drawing first, then starts building the paint up, lightest tones first, darkest tones last. I love the texture and the way it breaks up hard edges every now and then with a soft bleed effect.
I enjoyed playing around with it and thinking to myself "if it had just made this decision instead of that one, it would have turned out truly incredible (instead of just WOW)". So don't worry about it taking away any of your desire to paint. If anything, it gives you the itch to get back to your paints and make your own decisions. It may also give you an idea to take a painting into a different direction than you might normally have.
You've got to wonder if the artist is one of those jobs that will be automated someday, but I'm pretty sure you'll still need someone with a discerning eye to control the process. And hey, the 85 people who have the wealth of half the world's population will still want to by some original art!
Right?

Oh well.
In the meantime, I'm a firm believer in using technology to aid the analog art world and not replace it. Watching these appear on an iPad makes you want to watercolor even more and make bolder choices than the app itself makes. And if you have trouble unifying your washes, it will remind you how important it is to do so.
Here's some images that the app created from some of my photos. It doesn't work so well on people, as you'd expect. That's where the artist still triumphs.
Highly recommended. Try it out if you have an iPhone or iPad. There aren't any plans that I know of to make a version for Android.
