Capital New York: The Wall Street Journal is set to roll out its first mobile-only product — a paid, digest-style news app that is said to be an ambitious project for the paper as it consolidates resources around digital and reconfigures its newsroom through staff buyouts. The app will be called What’s News, named for the signature news briefs column that has long anchored the Journal’s front page. The app, which will enter beta testing next month ahead of a rollout on Apple’s iOS operating system, is described as a scan of the day’s most important news stories broken down for readers on the go.
