Smartwatches have developed into true all-rounders over the years and their range of functions is sometimes even superior to smartphones. Depending on the model, the smart wristwatches are either at home in the Android or Apple ecosystem. Apple watches can only achieve their full potential in connection with an iPhone, while Android smartwatches are not tied to specific devices. Samsung devices still work best with smartphones from the same manufacturer. In this article we have summarized the most important functions of a smartwatch for you and at the end we will introduce you to some of the most popular smartwatches and their functions.
What can a smartwatch do?
The design, range of functions and compatibility of the smartwatch differ depending on the manufacturer and model. However, basic functions are now supported by almost all devices - including the inexpensive ones. The main functions of a smartwatch are:
- Synchronize important data with the smartphone : weather, time, messages and calls are displayed on the smartwatch.
- Counting steps : A step counter is part of the standard equipment and should be present in every modern smartwatch.
- Play music : You can control the music collection on your smartphone remotely with the connected smartwatch.

- GPS function : Thanks to the integrated GPS, map apps or route planners can be used.
- If you use a SIM card (E-Sim), you can operate the smartwatch completely independently of the smartphone and thus make calls , send messages , etc.

- Flashlight function : The display can be used as a flashlight by showing a bright, white background.
