Photo touch-up for the masses

Does a few things really well, handy controls, functions quickly
Some features don't work as well as advertised
Facetune for Android lets you do a few simple photo touch ups very well. The touch-ups that Facetune is particularly good at are: whitening teeth, covering up spots and blemishes, and smoothing out wrinkles a bit. You can also use Facetune to defocus the background, and to "increase detail" for your eyes, or features you want to make really stand out. Facetune will be useful if you don't like your yellow teeth, or often want to get rid of a bit of acne in your photos.
The features that Facetune doesn't do so well on are applying tones to your skin, "gently reshaping your features" or trying to give yourself lipstick, or makeup or change your eye color. I found that as soon as I began reshaping a face, it didn't look natural. Reshaping was good for producing comical effects, but not for giving yourself a smile or a smaller nose. The tones feature in Facetune is also very heavy handed. It was too easy to overdo it, and too difficult to select an appropriate colour.
Personally, I don't think that the virtual touch-up features in Facetune really make people look more attractive. I find that smoothing people's skin removes character from faces, while whitening the teeth mostly draws too much attention to them. You look like a model in a toothpaste ad. Using the Detail tool really does draw more attention to the eyes, and other features, which can help make photos more immediately engaging.
The controls in Factune work really well, allowing you to compare before and after each effect as you apply it; and then compare all your effects together with your original photo. Most tools have an erase brush, so that you can remove the effect gradually from particular areas.
