So you're in a video store wondering if you want to rent or buy a particular DVD. Simply take a photo of the cover, and SnapTell will quickly return info that includes rating, description, links to Google, YouTube, Wikipedia, IMDb, eBay, Barnes & Noble, and more. You can quickly compare prices and find out what other people think about it. The comparison lets you compare local prices or online prices. In addition to DVDs, this free app can also give you info about CDs, video games, and books. It only works for U.S. products, but plans to expand soon to international items as well as additional product categories. I have to admit, this is a pretty clever tool.
