The most effective way to utilize Grocery iQ is to add items that you purchase frequently to your Favorites by clicking "+" from the Favorites tab and selecting items to build your list. You can then quickly add items to your Lists by selecting items from the Favorites tab. Just tap the circle next to each item in your Favorites and click "Add to List."
Add one-time purchase items that aren't in your Favorites directly to your lists from the List tab.
When you're at the store, check items off your list by tapping on the items to keep track of what you've placed in your cart. When you tap "Checkout," the items you've checked off will be moved to your History and cleared from your list! The items you have not checked off will remain on your list so that you will know what you still need to purchase.
