Next Monday during its developer conference Apple will introduce a new feature for iPhones and iPads called "Digital Health," Bloomberg said on Thursday.

Digital Health — said to launch as part of Apple's new iOS 12 operating system — will reportedly help users manage how much time they spend on their iPhones and iPads with tools that show how long users spend inside apps, according to Bloomberg.
