Would be great to see an app that can scan a grocery list and rank items based on where they are in the grocery store. In other words, the app would tell you what order to visit items in the store. Many of us visit the same store each time to get food, so this app could store the layout of the store and come up with the most efficient route as you add items to your list. The app would then give you turn-by-turn directions from one item to another.
