Hi, I have been trying to find a good app for progress note documentation to use at work. Since I have not been able to find one I like after a year of searching I want to write my own. Problem is I don't know how. Is there a book, or program that anyone recommends that teaches one how to write apps? I have decent computer literacy skills, ancient programing skills, (on punch cards if that tells you anything!) and access to a mac laptop if I can pry it away from my son. I want the app to be compatible with 3rd generation Ipads and Iphone 4 if possible. Any information would be appreciated.
