While just about every big newspaper has a smartphone application these days, Dale Jefferson's Newspapers app gives you access to a broad swath of them in a single app. With news from dozens of papers from across the U.S., Canada, the U.K. and France, there's no reason to ever feel uninformed about current events.
Of course major papers such as The New York Times, the Chicago Sun-Times, the Guardian and Le Monde are represented (as well as online news sources like CNN and the BBC), but even regional papers, including the St. Louis Post-Dispatch, Arkansas Democrat Gazette and Fresno Bee, are listed. Some papers have additional features; The Wall Street Journal, for example, includes a stock symbol search.
The Newspapers app taps into the publications' mobile sites -- each one carries its paper's unique branding, layout, types of news and so on. There is no search -- the stories simply go back as far as each paper's mobile page goes. For just under $2 (specifically, $1.70), you can upgrade Newspapers to allow you to save favorites, if that seems important.
