No easy way to export

There is no easy or intuitive way to export day although the description clearly says this is possible.

Empty promises

This app does NOT produce reports that can be shared or viewed. The reports don't have any use as far as detecting food sensitivities - you basically can only see a timeline that shows how many symptoms you have had and does not relate the symptoms to foods. It does not put the foods and symptoms in order as you eat/experience them (noon may show up before 6:00am, for example). If you make a mistake entering an item, it can't be fixed.
I feel that I was mis-led. This app doesn't do what it says. I upgraded to the $2.99 version because I thought these "features" might be locked.
I wouldn't waste my money or time if I were you.
I hope the book isn't as bad as the app. I ordered it yesterday and downloaded the app to use with it.

I loved the book and am using the diet with success but the app doesn't do much. It doesn't store your weight for some reason which is strange because it's also supposed to graph it under the reports tab. I have to return to the grocery store (heavy sigh) because the red pepper was not included in the ingredients list for the curry rubbed chicken so using the shopping list feature was useless. There is no way to print your grocery shopping list either and I wish there was.
On a more positive note, the symptom tracker made me realize that the soy sauce in the wilted spinach was making me sick.
