Oprah has launched mobile apps for BlackBerry, iPhone, Android and webOS. Why such a full court press on mobile apps? For one reason – it’s Oprah and she can do that. Also, apparently the 3.4 million followers on Twitter aren’t enough.

So just what do you get from the Oprah app? Viewing of clips and previews of upcoming episodes of The Oprah Winfrey Show, checking showtimes anywhere in the US, weekly polls, audio clips from Oprah Radio, articles from The Oprah Magazine, photo galleries, keeping tabs on @Oprah, and other fun show and personality interactions.
