I agree that Australian jargon makes this app challenging for American user. I found the app useful to some extend. It does help to have a list of foods for cooking from scratch handy. I didnt like the diary because it offered only a pre-set list of symptoms...some of mine were omitted. Besides having the menu to choose from may be helpful for some, but for those of us who dont have a personal chef it is annoying....I had to type my meals in.
