Apple Inc\'s Worldwide Developers Conference held in San Francsico\'s Moscone Center could be pretty much summed up as "The app that I can\'t live without."

Kicking off their 25th annual WWDC on Monday, Apple chose to forgo the revelations of new hardware in favor of updates to software and the introduction of new developer-focused features, including a new coding language.

The kick off event of the day was the announcement of Apple\'s desktop operating system, OS X Yosemite. The current operating system, Mavericks, which was released last year, was seen as a major overhaul of the 13-year-old operating system. This update is essentially a facelift for OS X. New features on Yosemite include better search integration, notifications with widgets, and windows with transparency.

Moving on from desktop, Apple also introduced new updates to its mobile operating system iOS with the announcement of iOS 8.

Cook claimed that iOS 7 has an overall satisfaction rating of 97 percent and that "nearly half of our customers in China have switched from Android to iPhone".

According to Apple, iOS 8 builds on the clean and slick design of iOS 7. The biggest new features include new interactive notifications, health tracking, as well as many Continuity features found on the Mac.
