Startup Idea: GPS-based Shopping Application

Startup idea to develop a new kind of shopping app that uses GPS to help shoppers navigate in-store. The app will allow shoppers to enter their shopping list and then guide them via navigation to locate each item on their list within the store. Stores can also use the app for better item display and location.

This isn't work related, but I'd love a new type of shopping app (or feature added to an existing one) that allows shoppers to basically GPS themselves within the store. They'd make a shopping list, then upload that list to the app, then the app would direct and guide them via like a GPS navigation. With step-by-step illustrations as to where the shopper is, and where items on their list are.

Stores could also use this feature to better display where and what items for sale are located.
