The app has a clean look, with a single photograph from a current news event filling the home screen. Users can scroll through articles that are each made up of blocks of text pulled from different news sources reporting the same story.
There are links from the original articles at the bottom of the page, which presumably helps Yahoo avoid charges of copyright infringement for republishing other people's content.
There are a finite number of articles, and readers are rewarded when they finish their digest with a message telling them they are "done." That satisfactory sense of completion is missing from people's online news experience today, according to D'Aloisio.
Mayer also announced that Yahoo will start to publish online magazines, with the first two being Yahoo Tech, edited by former New York Times columnist Pogue, and Yahoo Food.
They'll shun banner ads and instead use "native content," which are articles provided by advertisers and styled to resemble other content in the magazine.
It's a controversial way for publishers to make money. Critics say it makes it hard for readers to know when they are reading sponsored content, but Mayer said the native content will be clearly marked.
