“CBS This Morning” has launched a free app for iPhone and iPad. All of the features one would expect from a news app, including text stories, video, photos and Twitter feeds from anchors and correspondents. It also features “The Rundown,” a breakdown of the day’s news, as well as local weather,which is fitting as the actual “CBS This Morning” doesn’t have a weather anchor, leaving that to affiliates.

CNN is releasing a “digital magazine”–its first–for the iPhone, iPad and Android devices. The magazine, “Slavery’s Last Stronghold” is part of the channel’s “Freedom Project” features video, text and interactive components. A special report will air on-air and online, with additional components accessible through the app.

Time lists the best Twitter feeds of 2012, and Romenesko lists all of those in the “News & Information” category. Among them: CNN’s Anderson Cooper, Univision’s Jorge Ramos, NBC’s “Today,” BBC Breaking, Al Jazeera English, Lisa Ling, NY1′s Pat Kiernan and our sister blog GalleyCat.
