Notification messages are sent from the iPhone device and delivered to Apple Watch with small haptic taps on the wrist, while Glances offers small pieces of information that can easily be digested in a few seconds without having to pull your iPhone out of your pocket.

Since the release of Apple Watch, the Apple developer community has embraced this new piece of technology...
