Difficult to use

This app is only fair. It is easy to input items to a list. However, everytime I am in a store, with iphone in hand and app opened, items disappear from the list and go to the cart - and I dont touch a thing. Its a pain to have to retrieve them from the cart, multiple times. Im looking for a replacement.
