There are millions of grocery shopping apps out there, however, my idea is different. It is tailored specifically for Walmart. This is what I have in mind:
#1. An app that creates a grocery shopping list that has the aisle number next to each item. I'm sick of getting lost in the store not being able to find items and continually having to ask a store employee.. if I can find one.
#2. Categorize each item numerically by aisle so time spent in the store is reduced. By doing this you give the shopper a route to follow while in the store.
#3. If you're in the store and can't find an item you can "enter" the item into your phone and it will tell you where the item is located.
