I should have heeded the other reviewers warning not to purchase this app. It does not save anything you do. Sure, it can scan a UPC, but it will not save it. It can take a picture of your card, but it will not save it. If you scroll through the three demo cards included with the app, it will hang if you try to scroll past the third, causing you to have to kill the app. Im going to ask for a refund, not because I want the .99 back (my time is worth more than that), its the principal; developers shouldnt get any money for apps that completely fail to deliver the advertised functionality.
