Great Basic Tree ID – TreeBook Review

It has a hundred trees, as advertised, and it will identify them EASILY by their leaves, i.e. a "leaf key". I'd be happier if it had more trees, as some common ones are missing, and I'd like to see an ID key that works in the winter (no leaves), and it could use some more photos of the trees and their features (user submitted, maybe?). But it's the best tree ID app I've found for under $4 (disclaimer: I refuse to buy one over that price). I haven't tried contacting the developer yet, but I will make some suggestions soon.
