I purchased this app thinking itd have to be great - I mean, its from National Geographic right?
Meh, not so much.
There are no photos at all. In my opinion, illustrations are an artists interpretation of what the bird looks like, and quite often dont even really look the bird - I like the photos for comparison.
There is also no way to make any sort of list. I wanted to select the birds that I have in my area and add them to some sort of list, but you cant do that in this app.
I bought this app and iBird Explorer Canada - there is no comparison. Buy iBird and leave this one here (unless you want to use this is a back up to the other).
I get the feeling that Nat Geo rushed to get this in to the App Store and didnt really put the effort in to developing it. It should be a lot better than it is.
