Startup Idea : Where are my groceries?

Have you ever been in a supermarket and have no idea where an item is? You walk around looking clueless, and all the employees are nowhere to be found. In this app, whether it be at Walmart, Kroger, Public, Costco, ect. the user would enter the location of the supermarket they are at. There would then be a search bar to enter the item the user is having trouble finding. The search would then display the isle and placement of the item.
