You already know that using a grocery-list app makes shopping faster (hello, automatic sorting!), but mobile apps are constantly coming out with new features to save shoppers' money. Ones such as Favado, which has been around for about a year, show you the best deals in your local store on the products you're interested in; you just have to create a list so it can continually track those items and brands. Favado says it can help you trim your weekly bill by up to 70 percent (right now, the average shopper of boneless chicken breast saves 26 percent; the average shopper of apples saves 17 percent).
