Galaxy Watch 4: the first watches with Google Wear OS 3 measure your body composition

(CNN Spanish) – Samsung introduced together with the Galaxy Z Fold 3 and Flip 3 the Galaxy Watch 4 as the first series of smart watches with Wear OS Powered by Samsung, also known as Wear OS 3, the new generation of the operating system for smart watches that Google revealed in May as the union of Wear OS, Tizen and Fitbit (now part of Google).

This watch series actually consists of two versions, one called the Galaxy Watch 4 that looks like a new generation of the Galaxy Watch Active 2 and another version called the Galaxy Watch 4 Classic that has a physical rotating bezel like the previous traditional Galaxy Watch.

The Galaxy Watch 4 is Samsung’s first watch with a 5nm processor that promises 20 percent more power than before, further expands its internal storage to offer 16GB, and promises not only better battery life, but also speed improvements. loading.

BioActive sensor for better monitoring of your health

The Galaxy Watch 4 is the first watch to integrate the BioActive sensor that combines three powerful sensors in one without sacrificing detection and precision, at least according to Samsung.

This BioActive sensor combines an optical heart rate sensor, bioelectrical impedance analysis, and a sensor to perform electrocardiograms (ECG).

With this, users can detect blood pressure, arrhythmias, blood oxygen levels and, for the first time, body composition. With this, users can gain more detail on health and fitness through key measurements such as body mass, basal metabolic rate, water and fat percentage. All of this can be done in just 15 seconds by placing two fingers on the watch – the watch will measure over 2,400 data points.

Other exercise functions such as the trainer that encourages you to continue working, the possibility of exercising and showing your status on a Samsung television or measuring the Vo2 are present.

Sleep and snoring monitoring

Samsung still offers a feature that allows you to monitor sleep, but promises some improvements to get more detailed details of the quality of sleep.

Even when you sleep, the watch monitors the oxygenation of your blood, detects snoring to combine it with other data to provide you with a sleep marker.

Wear OS 3: Tizen and Wear OS in one

Google and Samsung join forces to take their operating systems for smart watches with Wear OS 3, or Wear OS Powered by Samsung, to another level.

This is the first watch with this operating system, but it has Samsung’s custom interface (One UI) that would make the experience a little different than what we would see in watches from other manufacturers and possibly even from Google.

However, this new operating system allows the app ecosystem to be unified to bring more apps to the two platforms and thus offer a more consistent experience that allows it to better establish itself to face the Apple Watch.

In addition, Wear OS 3 allows cell phone settings (such as a Galaxy S21 Ultra and possibly as the Pixel 6 Pro will offer) to be automatically transmitted to the watch to offer consistency in user preferences. Even apps installed on the cell phone are automatically installed on the watch when it is available.

This unification also allows Bluetooth headsets to automatically switch devices depending on use.
