I had some bugs on my rose plant, took some pictures and then i took the bugs put it in a ziplock bag, and i took few photos. one of the photos i took next to a penny, so after i downloaded the app, i used it to take a picture, now it does have an area of focus, so i made sure the bug is in that area and in focus, i took the picture, and it took only the penny part, AI my @#$$ , and it identified it as a red bug. since the app has an option to use already taken pictures, i tried (mind u that is the second attempt), it would not identify and it want to upgrade, otherwise it is as if i have done nothing. i tried few times and same , so I deleted it. waste of time. don't bother
