Location based apps are in high demand, and there are so many ideas yet to be implemented.

I’ve found an excellent post mortem style tutorial by Matt Gallagher demonstrating the creation of an app that gathers gas price info from an RSS feed, and displays nearby gas prices within a beautiful user interface.

The tutorial demonstrates Matt’s thinking during the creation process of the app and the tutorial provides for an excellent code example demonstrating a multitude of functionality including how to retrieve RSS feeds, how to cache the data, how to get the location, how to use geocoding within the Google API and much more.

You can find the tutorial and source code here:

It will take some time to go through this great example.
