This app is very user friendly. You can add additional items at any time. Items are categorized to make shopping easier, and you can change an items category if needed. I just updated so that I can add recipes to my file. When I want to buy items for that meal, it just takes one click and they are added to the shopping list. If you dont need an item, you can unclick it and it wont be added to the shopping list. Once you are shopping, you tap on an item and it disappears. You can sync with others so that more than one can add to the shopping list. SO easy!
