Find the cheapest gas: These apps make it easy

Thanks to GPS and crowdsourcing, it's now easier than ever to find cheap gas prices on the road. Here are three apps that could save you some money.

Gas Buddy is a popular app to find low prices because it's easy to use and navigate. Users just search by their city, state or or code to get gas price information.

Gas Buddy users -- and there are a lot of them -- enter the information about gas prices, and updates are usually pretty fresh. There's even a heat map to help users find prices across the U.S. and Canada.

Gas Guru's big buttons and large fonts give it a simple, easy-to-read interface -- and it also gives users prices and which services gas stations offer, like automatic car washes. Gas Guru can also provide directions to gas stations.
