Apple unveils iOS 8, OS X Yosemite

During the Worldwide Developers Conference in San Francisco, Apple Inc. (Nasdaq: APPL) CEO Tim Cook took the stage to announce the latest features for iPhone, iPads and Macs.

Portable devices can download the new iOS 8 and Macs can download OS X Yosemite, both free for all users this fall.

CNNMoney reports one of the biggest additions to iOS 8 is a new HealthKit application. The app will monitor users' heart rates, sleep, weight and blood pressure among other health-related information. HealthKit will allow clinicians at the Mayo Clinic to send health information to a user's app, which can in turn send that data to a user's primary physician. It also syncs with third-party fitness devices and apps.

Other iOS 8 upgrades include:

• HomeKit, new platform that would enable people to control all the items in their homes;
• allowing users to respond to texts or like something on Facebook directly from the notification – even on the lock screen;
• a double tap on the home button reveals several frequent contacts, allowing users to call, message or email those people;
• a predictive text feature allows users to type, and iOS 8 will suggest the next word based on typing history;
• notification screen widgets allowing users to view app information at a glance, including sports scores and weather data;
• improved group messaging where users can send audio and video messages and leave a group text with a new do-not-disturb feature; and
• a family sharing feature allows parents to track their children's  locations and seek approval on their iPhones or iPads before their kids can purchase new apps on their own devices.

The Yosemite platform has been upgraded to reflect the look and feel of portable devices with features such as spotlight.
