Such a nice concept but this app has NEVER worked for me. The first time I downloaded this app (3 yrs ago?) I was working with a rather old iPhone so I thought for sure this must be the problem.. but now I have a brand new, up to date, all the bells and whistles iPhone and this app cant even identify a common tomato plant or a common leaf from a tree that grows everywhere! I live in WA state which is known as the evergreen state, I was sooo hoping this app would finally work :-( Error messages is all I receive. Sorry Dev(s) its time for me to delete.
