Google has jumped into the shopping app fray with “Google Shopper,” which stands out from the crowd by being able to id products by their cover art. The feature works on book, CD, DVD, and video game covers. You can also search by voice, along with the usual barcode scanning, local pricematching and the ability to save items. If you’re a RedLaser fan, this could be a serious contender to replace it on your home screen. The app is free and available on both Android and iOS.
