ShopAdvisor is an excellent shopping companion. After selecting an item from the app by searching or with the barcode scanner, the app will find all relevant data that will assist you in your purchase. ShopAdvisor will grab all online and local prices, product ratings and descriptions, and a very useful price history graph. If you choose to “watch” the item, then the app will alert you if the price drops.
I was impressed with ShopAdvisor and seems to compare favorably to other similar apps. I particularly enjoy the feature that scans your Evernote account for gift ideas.
