I'd like a shopping list app that I could link straight to my online shopping account. It really annoys me that I can't do that on the supermarket sites already. It would save me loads of time as I buy different things online every shop.
Its pretty simple to do this with iPhone notes already - DH and I can easily do a shared list - anything I put in notes appears in his notes too if you share an Apple account. Would this be fundamentally different?
