There are two main uses for location aware apps

There are two main uses for location aware apps, one is for sales and the other is for awareness and information. Groupon is using their location aware app to drive local deals and sales and provide customers with the deals closest to them. Google on the other hand although they may be paid through PCC campaigns from the company without that campaign the information box for the local business will still show, so they are attempting to provide information instead of drive sales. This is shown through Google as they provide you with a local address and phone number before showing you any products from the business.
