What Is a Smartwatch and What Do They Do?


Everything you need to know about smartwatches

A smartwatch is a portable device that’s designed to be worn on a wrist. Like smartphones, they use touchscreens, offer apps, and often record your heart rate and other vital signs.

What Do Smartwatches Do?

Most smartwatches—whether they’re intended for daily use  or for specific purposes offer a suite of standard features:

  • Smartwatch NotificationNotifications: Smartphones display notifications to alert you of important events or activities. The types of notifications differ; devices connected to a smartphone may simply mirror the phone’s notifications on your wrist, but other smartwatches display notifications that only a wearable could provide. For example, the newest Apple Watch includes a fall sensor. If you fall while wearing the watch, it senses your subsequent movement. If it doesn’t detect any movement, it sends a series of escalating notifications. Fail to respond to the notification, and the watch assumes you’re injured and alerts authorities on your behalf.

App ecosystems vary, and they’re tied to either Apple’s or Google’s environments. Smartwatches with a dedicated purpose, such as hiking or diving, generally support the apps they need to accomplish that purpose without the opportunity to add other kinds of apps.
  • Media management: Most smartwatches paired with smartphones can manage media playback for you. For example, when you’re listening to music on an iPhone using Apple’s AirPods, you can use your Apple Watch to change volume and tracks.
  • Calling SmartwatchAnswer messages by voice: Remember the old James Bond movies, where the hero detective used a watch as a phone? Modern smartwatches running either the watchOS or Wear operating systems support voice dictation.
