While we still don't have a precise release date for the Apple Watch, the Cupertino firm wants to make sure we'll all have plenty of apps to play about with on the timepiece once it does hit shelves. Apple's just released its WatchKit developer kit resources, letting iPhone app makers and would-be Apple Watch software designers get to work on the new wrist-based device.
"Apple Watch represents a new chapter in the relationship people have with technology," reads the development kit landing page.
"Starting early 2015, you will be able to deliver innovative new experiences to your customers on their wrist. Learn how your existing app notifications can easily show up on Apple Watch. And by leveraging WatchKit, you can take your apps even further by extending and enhancing their functionality on Apple Watch"
According to the page, WatchKit apps will have two parts -- a WatchKit extension that runs on an iPhone, and interface resources that sit on the Watch itself. Launching an app on the timepiece triggers the iPhone extension to run in the background, which then updates the Apple Watch interface in response to a user's actions. From this description, it appears that you won't see many independent Apple Watch apps, if any -- they seem heavily reliant on a supporting iPhone app.
