Not so useful
The app is limited in scope, and not very effective in any kind of photo with varying background. If you want to remove an object “floating” in a very consistent background, it works OK. BUT, if you want to remove a battery resting on the edge of the arm of the couch, with a bit of wall in the background, forget it! The app has no concent of boundaries, and trying to remove an object that sits in front of two different surfaces, or sits on a crack or a seam, is impossible.
Even on a consistent background, it requires some clean up after removing an object. What the app seems to do is cut out whatever you paint, and then try to clone in surrounding pixels. It does an OK job of reproducing texture, but only if the entire surrounding background is similar.
Lastly, MacPhun puts every photo editing feature in a separate app. If you want all the features, you will end up paying more than buying a full-featured product. Or, you could just use GIMP.
