We also have an easy way to mark things as 'want' and 'have' and to share them on Facebook. But yes, real-time scanning of the shelves is a key differentiator.

If you don't mind my asking, how long does the process take you with Amazon's app? If that process could be sped up substantially, would you scan more products: multiple options for any one purchase, and less expensive products too [1]? The UPC scanners take too much time [2] and too much effort. Steps: find and extract box, aim for its UPC (maybe while awkwardly balancing the box in one hand), wait several seconds to get simple data like average rating. Then: put box back in its place, touch 'back' on phone, repeat steps for next product. [1] - Judging by the # of reviews on Amazon for even trivial items like HDMI cables, people like to research all kinds of products, as long as it's quick and easy. [2] - The whole process with UPC scanners takes me about 10-20s, whereas ShopSidekick takes 1-2s.
