Grocery Store

We have now established our group and created our idea. We are all very excited about the idea of an all store (Costco, Target Etc.) map app. It would help shoppers who want to get in and out of stores fast and efficiently by providing a map that has the items on your shopping list listed. A problem that we could possibly face is within our group, none of us know how to design or start an app. Our goal is to create a survey to ask people if they would use the product. We have a concept logo below.
Would you use this?
