Pop punkers Good Charlotte -- known over the years for their high-octane music -- have a brand new app! The GC app is available now at the iTunes store for iPhone/iPod Touch/iPad.

The app allows 24/7/365/52 access to the band and will provide fans with news and information, as well as the ability to listen to and purchase tracks from the new Good Charlotte album 'Cardiology,' released last fall.

In addition, fans can also follow the band on tour via Twitter and YouTube activity. There is also the 'Motivate Me' Facebook app, which provides a little motivation during the day when you’ve hit the wall. It is the ultimate app for fans of the Brothers Madden and their music.

Good Charlotte are currently on tour in support of 'Cardiology.' Joel Madden also married longtime girlfriend and baby mama Nicole Richie at the tail end of 2010.
