GasBuddy is a nice Windows Phone 8 app that lets you find gas stations and real-time gas prices from the comfort of your Windows Phone. You can search by keyword or by your current location. The app was recently updated to version three to bring a handful of tweaks and performance fixes as well as Windows Phone 8 support.
The update also brings lockscreen support and offers randomly changing wallpaper images. We'll reserve judgment on the quality of the wallpapers once we see more but the first seems a little on the dark side.
The nice thing about the lockscreen support is that current average fuel price for your location, for the State you are in and the Nation will be displayed on your lockscreen. It takes a few minutes to pull up the information on your Windows Phone lockscreen but it's a nice touch.
GasBuddy is a free app for your Windows Phone 8 device that you can find here at the Windows Phone Store.
Thanks, cruisezero, for the tip!
