This is my favorite app for shopping list management. I love it for the synchronization. I can add things to the list when I find we are running low or completely out and it automatically synchronizes to my wifes phone. So when either of us are out shopping we can have an up to date list of what we need. It is also nice when we are both at the store together. We can split up and save time. As we each mark things off, the list continues to synchronize so we don't end up grabbing the same things. Totally love it.
