The Apple Watch offers an additional level of convenience to iPhone users by allowing apps to take advantage of a new set of features that offer interactivity at the flick of the wrist.
The Apple Watch includes a variety of features such as force touch, a digital crown (for scrolling & zooming), haptic feedback, a near-field communication (NFC) chip (for mobile payments), glances (customized views of information), and a heart rate sensor. These features interact with the Apple WatchOS, its integrated HealthKit & Siri voice activation to allow for easy navigation of information & activities on the device despite its small screen.
