Favorites tab gives a quick access to items you buy most often. Just tap an item and it gets instantly added to the current shopping list. A yellow star indicates that item is added to the current shopping list.
You can add items to Favorites as you would for any shopping list: Add button (plus), Voice input, Barcode scan. To populate Favorites from Pick list or History just select Favorites as destination list on top of Pick list or History and tap items you would like to get added.
List-specific favorites feature allows you to associate a list of products with a certain store. For instance, if you buy fruits from Whole Foods and milk from your local grocery store, with list-specific favorites it is possible to list fruits under Whole Foods’ favorites, and milk as favorite for your local grocery store. Please see Manage shopping lists User’s Guide for more details on how to configure list-specific favorites.
