This App was unable to detect any alteration in 4 of the 5 images with which I tested it. On the plus side, I clearly showed where a pimple had been removed from a photo. Unfortunately, Photo Police was completely unable to detect where I had removed a car from several other photos.If you want to make sure that your friends aren't removing pimples from their photos, this is an acceptable App. If, however, you need to check the validity of a photo, Photo Police appears basically useless. -Professional photographer 10+ years.

Very good for dectecting small things in "big" areas for example a pimple on a face or a bug on a flower; but for example I eddited out two children playing on beach and it faild to notice but spolch of the space they where in. The program also did a very good job on HIGHLY editied photos, I changed contrast, tone and color, of a moon shoot at night even brushed out a building, tree and power line and i could clearly see using this program the tree building and line ( though no hint of tone contrast or color change). -All in all for a FREE app that works 4/5 times its very useful for exposing edited photographs.

If you cannot open a photograph file, you cannot use this. I wanted to like this instead of using online software. It has not been updated for 10 years or so, so it is not going to be so.

Not useful at all, since it doesn't even open a png file. Waste of time.
