This week Amazon released a free iPhone app that provides more native access to the Amazon store experience. It has the expected features like product search, product data, reviews and of course, 1-click purchases. In addition, Amazon has introduced a new experimental feature called Amazon Remembers.
Amazon Remembers allows customers to snap photos of objects of interest and upload them to Amazon. Once uploaded, Amazon uses MTurk to identify the product and within minutes the app notifies customers with a link to the matching product. In my tests, an iPhone snap was identified as the iPod Touch (since Amazon doesn't sell iPhones), a Pepsi can returned a link to Coca Cola (since Pepsi is not sold on Amazon or some MTurker has a wicked sense of humor), a Palm Z22 was not identified, and a book was identified perfectly.
Get the app from the iTunes app store.
