New York (CNN Busienss) Apple rolled out new features designed to track and limit screen time. Then, it started policing the competition, according to a New York Times report published Saturday.

The tech giant has removed or limited the features of some of the most popular third-party apps to monitor screen time, including apps that gave parents tighter control over their children's phone use, the report said.
