If you have an ounce of brains, you can get very good results, and in VERY little time. If you are expecting magically perfect results without any discernment on your part, you will probably be disappointed.
I am a pro photographer and a successful painter/illustrator. I have very high standards, and Ive gotten some excellent, seamless results using anticrop. As often as not, I havent needed to finish in more advanced (and expensive) software. It saves a TON of time and effort when compared to something like Photoshop, and for the price there is nothing else that even comes close to what this app does effortlessly. OF COURSE there are some photos that do not anticrop well, but come on – it costs 99¢!
Maybe the critics should shell out $700 for Photoshop and use it instead, and take their useless vitriol with them.
