The Samsung Galaxy Watch 2's advantage over the upcoming Apple Watch 6 may rely on a feature that actually debuted on the Galaxy Watch Active 2 but was not previously accessible.

As noted in our review of the Galaxy Watch Active 2, Samsung's latest wearable includes a blood pressure monitor, but until now it has not been approved by health authorities to enable it. South Korea's Ministry of Food and Drug Safety (equivalent to the FDA) just approved the Samsung Health Monitor App, which will enable the monitor on the Watch Active 2 and future Galaxy Watches.

When paired with the Watch Active 2, the Samsung Health Monitor app can start measuring blood pressure. However, according to an informational video about the new feature, users must first calibrate their smartwatch with a standard blood pressure monitor.

A standard blood pressure monitor with an inflatable cuff, such as those found in doctors' offices, can be purchased online for about $50 (see Best Buy's 5-star option here). After purchase, the Galaxy Watch can be used monthly to maintain accuracy, during which time you simply check the readings on your wrist.

Not everyone needs to keep an eye on their blood pressure, but for those who do, the Galaxy Watch Active 2 or the upcoming Samsung Galaxy Watch 2 will be one of the best smartwatches you can buy.

South Korea is the only country that has approved the blood pressure monitoring feature, but other regulatory authorities where Samsung wearables are sold are likely to follow suit.

Therefore, it is reasonable to assume that the Galaxy Watch 2 will offer this and all its features at launch. The new wearable may debut at the Samsung Galaxy Note 20 Unpacked event later in the summer.

The Apple Watch holds an advantage over the Galaxy Watch because of the ever-increasing features of Apple Health, and when the Apple Watch 6 debuts alongside the iPhone 12 in the fall, we expect it to first challenge whatever Samsung offers We expect it to challenge even.
