Shoppers in full holiday shopping mode will be happy to hear that Decide.com has updated its iPhone and iPad applications, making it easier for users to comparison shop and figure out if it's a good time to buy that new, big screen television. Decide said it updated both of its iOS applications, which it says makes it easier for users to navigate information and its shopping tools, which provide price predictions, price histories and graphs, and recommendations to users on whether or not they should buy products. The service covers everything from televisions, to tablets, and more. Decide.com said it has products now in over 75 categories. Decide.com recently switched the premium features of its service and app (covering pricing predictions and recommendations) to paid model.
