Launched in Summer 2011, is a shopping service that predicts when to buy consumer electronics by showing to consumers when the price of a particular product will be the cheapest. According to Michael Paulson, VP Product and Marketing, Decide, the service is powered by a complex predictive algorithm that gathers and analyzes over 60 terabytes of historical data from various sources, including online retailers and manufacturer’s websites.

Today, launched its iPhone app just in time for the holiday season, allowing consumers to answer the question “should I buy now or wait” while shopping in stores.

If you check the graphs that has produced regarding consumer electronics price variations (check it at the end of this post), you would be very surprised to learn that older versions of products do not necessarily drop in price once new models are introduced to the market, and Black Friday may not be the best time of the year to get the most valuable deals.

Features include (according to press release):

• Check prices: see the lowest prices online and nearby for hundreds of thousands of electronics products.

• Get instant predictions to see if you should BUY NOW or WAIT: just scan a UPC barcode or QR code while in-store, or search by model number.

• Check product ratings and reviews from other shoppers.

• Share your decisions made using  with your friends via email, Twitter and Facebook.
