Apple Watch represents a new chapter in the relationship people have with technology. 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.

This is a huge day for Apple. It may seem like this is just another SDK release for developers, but this is where Apple learns just how interested developers are in making apps for its new device. We’ve all seen it before with companies competing with Apple for iPhone and iPad apps—they matter to the consumer a lot. Products that don’t have deep developer support have a good chance of failing. When Apple does release the Apple Watch next year, they want to be able to stand up and brag about how many apps are already available. It’s an important day.
