Press for iOS allows you to create multimedia slideshows on your iPhone, using photos you take, sounds you record, and text you write. You can send these slideshows to other users, who can add or edit the photos and sound as a group. A slideshow can evolve greatly over time and between users, so our backend keeps a version history. Any slideshow can be posted to Facebook or disseminated in a Tweet, where it is viewable on the Web. to anyone with the link.
