The app features a list of broad news categories under 'stations', which carries content from specific news sources.
The company's app competes with Twitter Inc's recently launched service called Moments, which aims to provide a better way of curating and aggregating news content for users and help them follow live events.
Facebook had earlier tied up with nine news publishers to launch 'Instant Articles', which publishes their content directly to the social network's mobile news feeds.
The company's shares rose 1.7 percent to USD 109.7 in afternoon trading on the Nasdaq.
