All these features are very useful for performing calculations, tracking your timetable, and tracking and sharing your live location. Here are some of the most common functionalities for which you can use your smartwatch. 

Receive Notifications

You can receive different notifications on your smartwatch If it’s synced with your smartphone. A smartwatch works just like your smartphone’s mirror when it comes to notifications. 

On the other hand, if your smartwatch isn’t synced with your smartphone then you still might receive notifications. However, they’ll be related to different activities that your smartwatch records such as pulse rate, heart rate, calorie count, and distance.

Run Different Apps

Smartwatches can run different apps to perform different tasks. Not only does it allow you to improve your productivity but you can also use it for entertainment purposes. How much you can take advantage of this feature depends upon the number of apps a smartwatch supports. 

General-purpose smartwatches usually support many apps for using social media, running music apps, replying to messages, tracking weather, and much more. Not only do these apps send notifications directly on your smartwatch but you can also interact with them to perform certain actions. For example, you can use a fitness tracking app to see the distance you traveled, calories burnt, workout duration, etcetera. 

A smartwatch also allows you to control media that’s stored in your smartphone. You can change the track currently playing and you can also increase or decrease the volume.

Reply to Messages

If you’re wearing a smartwatch, then you won’t need to bring out the phone from your pocket to reply to your emails and messages by voice. However, only smartwatches with voice command capability can perform this function. This feature comes in handy while driving or exercising. You can also answer important calls with a single swipe as well.
