Useless
Of course, the best way to find one of these apps that works for you is to test them yourself. Which I did with this disappointing app. For example: I scanned in a bag of Lays potato chips and got two results for on-line purchase and only one result for local stores selling Lays potato chips? I live within a couple of miles of all Los Angeles major grocery stores and it didnt return a single one of them as a result. (Its sole result for a "local" store isnt at all local to me which indicates that it gives results of stores that paid to advertise). The app is useless.
