This app is pretty good. It has a picture of the plants, well described on whats edible and not, where its from, etc. The only thing I think this app needs is to have more pictures on each plant as what its leaves (shape, orientation of each), flowers, roots, bark, etc look like so I can go out and determine whats what.
The information in this app can be found on the web for free, but when in the wilderness it would be nice to reference since there is no internet in nature.
