Shopping Helper - App

I am looking for an application, where you can take photos of products , the photos will be geotagged. The person can add either the actual price or have option of clicking on radio button to enter the price range of the product. The app should be able to identify and classify the photo and give references of similar products and the price range of product in nearby places. Another additional functionality expected in future is that this app should be able to speak to a gift registry website, where the user can add the photographed product to his / her gift registry. Or if he / she is an area where any person in his/ her social network has tagged a product then he/she should get notification.
