Is a full tank of gas a Realtors® best friend? Maybe not, but with all the driving they do getting a good deal on gas prices probably does make life a little easier. And you guessed it—there’s an app for that. Find gas stations close to wherever you happen to be with the best prices by trying one of these free apps for either iPhone or Android.

GasBuddy
Perhaps the most popular of gas apps, GasBuddy helps you locate gas stations near you and see their current gas prices with one click. The app creates a community of real time gas price “reporters” by awarding points toward prize giveaways to users. The app breaks gas prices down by gas types—regular, mid-grade, premium and diesel. You can search for gas stations based on either price or distance from where you’re located. It also provides a link to get directions to the station you choose.

GasGuru
Developed by Yellowpages.com GasGuru is only a month old so the jury is still out about the accuracy of its gas prices. However, in addition to gas prices this app also lets you search for nearby restaurants, coffee, auto repair, ATMs and roadside assistance—all of which can come in handy. This app rates gas prices  as either “Best” meaning it’s in the top 20 percent of the cheapest gas available, or “Good” meaning it’s in the top 50 percent, or other, which is any price not falling in the first two categories.
