When you are buying something or see something interesting at a store or wherever and wonder if it is worth buying, you need an app that can check for reviews online.
The idea is to create an app that will allow you to take a picture and it would perform a visual search online and show you real-time reviews (via Amazon and other top sources). It could also show prices and availability in different stores.
This app could be used to look up reviews for businesses as well.
