App tracks product price drops with a simple screenshot

Consumers often come across items they’d like to buy, but don’t necessarily have the money for them right at that moment or feel they may be able to get a better deal elsewhere. Apps such as PowaTag have already enabled users to scan any real-world object and find an e-retailer to buy it from, and now SnapUp helps mobile shoppers automatically organize the online products they’re interested in with just a screenshot, and lets them know when they go on sale.
