For a while, Gas was going down but it appears to be on the way back up. You probably want to find the cheapest gas around you, especially if you are in an area that you don't frequent that often. There are plenty of apps to help you out with that, and a few of the apps listed below, I actually use to find cheap gas each week.
This is one of the apps that I use quite a bit. Here you can find gas stations near you, as well as cheap gas stations in your area. Additionally, the data is provided by users, so you are able to update gas stations with new gas prices. Which is always helpful to other users.
Using Gas Guru, you can find the prices of gas at gas stations near you. While the UI isn't the best, it does its job. Additionally you can share the gas price at certain stations - normally the cheapest ones - on Facebook. Which can be a big help.
