What are the benefits of a smartwatch?

Having used smartwatches and fitness trackers for many years, I decided to do some research to add my own perspective on the practical benefits of using these devices. So what are the benefits of a smartwatch? Smartwatches allow easy access to certain smartphone apps and can also provide sensor data such as heart rate monitoring and sleep tracking that smartphones can't provide.

Sensors used in the health monitoring function

GPS positioning isn't quite standard yet, but it's certainly becoming so. A few years ago smartphones were not all equipped with GPS, but now they are, and so are smartwatches. Many devices also support the Glonas and Galileo positioning systems. GPS is essential for tracking your outdoor activities such as running, hiking, and cycling, giving you accurate speed readings and showing your activity on a map.


Accelerometer, which is designed to track movement and is used to implement for example a pedometer. It also plays a role in detecting movement associated with sleep tracking, for example.


A gyroscope is used to track rotation and plays a role in detecting the type of exercise you are doing and helps to track your swimming, etc.


Wrist-based heart rate monitor is obviously used to track your heart rate.


Barometric altimeter, compass, and thermometer. The barometric altimeter combined with the compass and thermometer is used to track your altitude, so is a good feature for runners and hikers.
