SAN FRANCISCO (CNN) - Apple unveiled plans for new operating software for iPhones, iPads and Macs.
CEO Tim Cook made the announcement Monday at the kick-off of Apple's Worldwide Developers Conference in San Francisco.
The mobile operating system iOS 8 will allow users to respond to texts or something on Facebook directly from the notification, even on the lock screen.
It also will include improved group messaging.
One of the biggest additions to iOS 8 is a new health-kit application.
The app will monitor users' heart rates, sleep, activity and breathing - among other health-related information.
The new operating system for Macs, called OS X Yosemite, features an updated safari browser and search feature.
Both operating systems will be available to users this fall.
