"The new Walmart iPhone app packs in a number of features, including a new smart shopping list tool that can be shared and paired with a new budgeting tool that pulls up real-time prices for products, so consumers can calculate their bill ahead of time. Walmart will also enable users to pull product information — including reviews, ratings, price and availability — from the app. They’ll also be able to scan QR codes for information.
In a test in a limited number of stores, Walmart will provide a store item finder tool that tells people the exact location of products. It can work with a smart shopping list, which can organize the products by their location.”
