Apple publishes videos that explain you how to use some features of the Apple Watch Series 4

Apple has released a number of videos today to show you how to use certain features of the Apple Series watch. This occurs when launching the latest version of the Apple smartwatch. The videos will show you how to measure your heart rate using the watch, launch an activity challenge, place a call, start a workout and ask for help to use SOS emergency.

So let's say you have a brother, a college boyfriend or a friend with whom you are very competitive. If you both have an Apple Watch Series 4, you can get into a seven-day head-to-head competition with the new activity competition feature for the latest version of the Apple smartwatch. According to the video (found at the top of this article), the first step is to open the Activity application. Swipe left and choose your opponent. After that, scroll down and click on "compete".

One of the most important features of the Apple Watch Series 4 is the heart rate monitor. On older versions of the device, the heart rate monitor has literally saved the lives of users. To measure your heart rate on the watch, open the Heart Rate application. Stay still and scroll to see your resting heart rate. Scrolling down will reveal your heart rate. Too high a reading may indicate a health problem.

Want to make a call on your Apple Watch Series 4? Lift your wrist to activate Siri. Ask Siri to call a name from your contact list. If you need to adjust the volume, turn the digital crown. And you surely know that the Apple Watch can follow your workouts. To do this, open the training application, tap the three-point menu to set a goal or press the activity itself to start your workout immediately. Slide your finger to the right to end the workout and scroll through the screen to get a summary including calories burned, average heart rate during training, and so on.

The latest video shows you how to call on the help of Emergency SOS on Apple Watch. Try to memorize brief instructions as you never know when it might be helpful and save your life. Press and hold the side button. Slide the "Phone Button" to make an emergency call. And that's all you need to do.
