APPLE’S Worldwide Developer Conference recently took place, the annual event where the digital giant reveals new features coming soon to iPhones, iPads and Macs.

There was no new iPhone or iPad to speak of, nor the rumoured iWatch, but Apple’s annual developers conference last week still left techies with plenty to get excited about.

The fact that software engineering head Craig Federighi did the lion’s share of the work on stage in San Francisco put hardware firmly on the back burner. High on the agenda was the unveiling of a new operating system, OS X 10.10 Yosemite.

Named after the famous American national park, Yosemite makes integration between Apple products easier.

For instance, using the Handoff feature, you can start a task on your iPad and finish it later on your Mac.

Yosemite will also let users send and receive text messages across all Apple devices and make phone calls, as Federighi demonstrated when he placed a call to rapper Dr Dre, whose Beats Electronics firm Apple has just bought for 3 billion dollars.

Other tech companies are often accused of aping Apple’s designs but this time, in what some see as a response to the phenomenally popular Whatsapp, extra features for iMessage were previewed including group messages and the ability to send voice and video clips.

Similarly, newly announced iCloud Drive was seen as a move into the already crowded arena of free file sharing apps, and a legacy of Steve Jobs, who once tried unsuccessfully to buy Dropbox.

With storage and sending capabilities up to 5GB, iCloud more than doubles Dropbox’s gigabyte allowance, but it’s still only a third of Google Drive’s generous offer and it won’t be accessible via the Android operating system.

No Apple conference is without controversy, though, and this time it came in the form of an Australian start-up also called Healthkit, who are not happy the Californian behemoth is using the same name. As HealthKit refers to the API (application programming interface) rather than a product, it doesn’t seem like they’ve got a legal case, but whatever the name, this could well be the start of an app a day to keep the doctor away.
