I find most of the bad reviews unfounded. 1) it was never designed for ipad. you are not gonna gave your ipad in your pocket while you work, but your iphone probably would be there. 2) what might be a plant that is a common planting in your area nay not be popular anywhere else. I have a degree in horticulture and work with trees and shrubs for a living and I find it very useful. It has the Genus, species, and common name. those are all you need to find what you are looking for. I have most of his books also. dont count on an update soon, as Dirr writes books not apps and the app is based off of his books some that do not have pictures. this is really designed for EDUCATED people in the industry, not know it all landscapers with no formal education.
