When you are in the store, it is nice to know if your partner added something to the shopping list after you left home. As you start putting items in the cart, just swipe them on the shopping list. When you do this, the app will automatically sync with our servers, and any new items added by your partner will appear on the list. You can also use the well known pull-to-refresh gesture, i.e. pull the grocery list downwards while you are the top to make the app connect to our servers again and refresh the list.
