Apple’s new Watch Series 4 may literally be a life-saver with its impromptu ECG functionality and fall detection that works best if you are 65 or older. As usual, however, most of its new owners would first appreciate how much more screen space you have when compared to the Series 3, and will mostly use its workout tracking and emergency SOS functions. Given that the new Apple Watch Series 4 sports automatic workout detection, as well as new workouts such as hiking and even yoga, it’s good to learn how to use this option straight from the horse’s mouth. That’s not to mention the advanced features for runners like the new pace alerts, too. The Emergency SOS function has also proven its usefulness numerous times already and is perhaps the first most important thing you need to learn to use on your Apple Watch in case you get into any kind of trouble that would require alerting family, friends or the authorities.
