APPLE is expanding into home and health management as the company tries to turn its iPhones, iPads and Mac computers into an interchangeable network of devices that serve as a hub of people’s increasingly digital lives.

The new tools for tracking health and controlling household appliances are part of updated operating systems that Apple unveiled on Monday in San Francisco at its 25th annual conference for application developers.

The revised software for Apple Inc’s devices won’t be released to the general public until this fall when the company is also expected to start selling the next generation of iPhones and iPads. A spruced-up line of Macs also could be coming before the holiday shopping season.

Disappointment

The lack of a flashy new gadget may disappoint some Apple fans who are still looking for proof that the company hasn’t lost its ingenuity since Steve Jobs died in October 2011. Since then, Apple has mostly been making incremental improvements to the devices and software hatched under Jobs’ leadership.

While those updates have been enough to maintain Apple’s status as the world’s most valuable company, they haven’t quieted persisting questions about the company’s future prospects amid intensifying competition from other device makers.

Apple CEO Tim Cook, Jobs’ hand-picked successor, turned Monday’s spotlight over to one of his chief lieutenants — Craig Federighi — to discuss the company’s upcoming software changes. The new versions, which will be free, are called iOS 8 for mobile devices and “Yosemite” for Macs.

The iOS 8 operating system includes “HealthKit” and “HomeKit” options that may test how just how much Apple customers trust the California company to keep their privacy.

HealthKit works with a new built-in app on the iOS 8 that will store a variety of information about people’s medical histories, vital signs, fitness levels and diet. Other third-party apps will be able to access the data with a user’s permission.

HomeKit aims to set up a system that lets an iPhone or iPad serve as the remote control of an entire household outfitted with assorted digital appliances.

Apple hasn’t given any indication that it plans to make these “smart” household appliances, although there is recurring speculation that the company eventually will release a TV set that gives its services access to the biggest screen in most people’s homes.

Digital butler

For now, Apple appears content serving as a sort of digital butler in homes. In a hypothetical example sketched out on Monday, Federighi said a homeowner with an iOS 8 device might be able to announce “it’s time to go to bed,” at which point doors would automatically lock, lights would dim and the thermostat temperature would be adjusted by Apple’s digital assistant, Siri.

The move into health and home coincides with Apple’s bid to make its services more accessible in cars. That system, called CarPlay, will be available later this year.

Some analysts suspect Apple might get into finances later this year with a digital payment service.

Another new feature included in iOS 8 is designed to make it easier to type on the smaller screens of mobile devices. Called “QuickType,” the tool will learn a user’s language patterns and suggest ways to finish sentences. For example, if you start typing, “Do you want to go to,” the phone will suggest “dinner” or “movie” as the next word. Currently, the suggestions are limited to spelling corrections.

Devices running on Google’s Android software, a more widely used system than the iOS, already attempts to fill in the blanks as people type.

Apple’s messaging app also is adding an option that will let users record and send audio and video to recipients instead of typing out a note. This feature copies other messaging services such as WhatsApp and Snapchat.
