This review is from: Audubon Butterflies - A Field Guide to North American Butterflies (App)
There is a lot of information in this app but the picture quality is poor in my opinion. The same goes for the bird app as well. I doubt i will buy another Audobon app unless they greatly improve the resolution of the photos or cut the prices in half.
