Overview of Features 

The Galaxy Watch 4 features the groundbreaking BioActive sensor from Samsung. It also boasts a more compact and smaller design that does not deviate from measurement accuracy. The new sensor is 3-in-1 and utilizes only one chop to operate three strong health sensors with utmost precision. 

The powerful sensors are Optical Heart Rate, Bioelectrical Impedance, and Electrical Heart Analysis. As such, the device allows you to monitor your blood pressure, gauge your blood oxygen levels, identify any AFib irregular heartbeat, and calculate your body’s composition. 

The new tool for measuring your body composition provides you with a more in-depth understanding of your fitness and overall health. This is done using key measurements such as basal metabolic rate, skeletal muscle, body fat percentage, and body water composition. In approximately 15 seconds, the sensor on the water will have captured 2,400 data points. 

The smartwatch also has a collection of wellness features through which you can remain motivated while tracking your daily activity levels. You can pick from a large selection of guided exercises or engage in group challenges with family and friends. 

You can also come up with an at-home gym by connecting the Galaxy Watch to a Samsung smart TV (compatible). Heart rate metrics and calorie counts will show on the screen, making tracking easy. 

When you go to sleep, the Galaxy Watch 4 provides a clear illustration of your sleeping pattern with details like never before. With a compatible smartphone, you can detect snore sounds and monitor your blood oxygen levels as you sleep. 

These enhanced sleep scores allow you to understand your sleeping patterns better and better understand what could be affecting your night’s rest. 

Ease of use, efficiency, and simplicity are some of the standout features of the Galaxy Smartwatch series. And together with the brand-new One UI Watch from Samsung and Samsung-powered Wear OS, the watch is designed to give you a seamless Galaxy experience. 

Thanks to One UI Watch, you do not have to worry whether an app is compatible with the watch. Compatible apps will be installed automatically on the watch once you have downloaded them from your phone. 

Furthermore, important settings such as blocked users and the do not disturb hours are immediately synced. This eases the problem of getting unwelcomed notifications from blocked contacts or during your relaxation time.
