I've only downloaded free apps. The ones I like are Quilt Shops (type in a town and it finds shops); QuiltingCalc (figures out yardage); QuiltSandwich(lots of quilt info); Joann (in case I forget my coupons); RetailMeNot (again in case I forget my coupons); and about 4 weather reporting sites because I'm a weather junkie. A few others I've tried and like Willferg said, if you don't like them, remove them.
