Gas Buddy, Gas Guru and Mapquest Gas Prices apps all show the current price for Walmart gas. The apps are available on Android and iOS phones and offer numerous searching and sorting capabilities, such as indicating stations closest to the user's current location.
Gas Buddy, Mapquest Gas Prices and Gas Guru also provide directions to the gas stations for which it lists prices. Gas Buddy relies on its users to input information on the price of gas they purchase and then organizes the information for other users. Gas Guru uses information on gas prices from an online database, so its prices may be updated more frequently. Each of the apps shows when the last price update occurred and indicates the price of different grades of gas, including regular and premium.
