What is Greed?
Greed is an RSS reader with Google Reader integration. You can use Greed to read your Google Reader articles, and maintain them from your phone.
The Full version adds offline caching and several other features not found in the Lite version.
Last version, 1.4.3, was released on October 2010. It can be still downloaded from Google Play, but, since it depends on Google Reader, it will be unusable from July 1, 2013.
