Advancements Enabled by Chips and Algorithms
Having been around for over a decade, the Apple Watch has evolved into a relatively mature product (another way of saying that new features are becoming less frequent with each generation). Nonetheless, it still manages to introduce at least one new feature annually. The latest feature will analyze bodily signals and send an alert if there’s a risk of high blood pressure, a health condition that is often silent yet can have severe consequences.
Specifically, the functionality will be available on Apple Watch Series 11, 10, and 9, as well as Apple Watch Ultra 2 and 3. The more budget-friendly Apple Watch SE 3, however, is not compatible, as its sensors and processor are not sufficiently powerful to support this precise tracking. Nevertheless, it will still benefit from the new Sleep Score, which is available on all models capable of sleep tracking.
Gradual Rollout, Pending Approval
As of now, this key feature has not yet been activated. Indeed, Apple is waiting for the green light from the FDA (Food and Drug Administration), which is expected to come by the end of September or in October. Once approved, a software update will automatically activate it for the compatible models.
In the meantime, the new models will be available on September 19, while watchOS 26 will launch on September 15, bringing a host of new features for all eligible watches.
With this approach, Cupertino confirms its strategy: to extend its major health features to as many users as possible, rather than restricting them to the latest models only. This strategy not only bolsters its image as a partner in wellness and prevention but also eventually encourages users to upgrade to the latest models to take advantage of more advanced hardware innovations.
How Does Apple’s High Blood Pressure Tracking Work?
In this new release (and as rumors anticipated), the focus is on health, particularly with a feature for monitoring chronic high blood pressure. The Apple Watch’s high blood pressure notifications rely on the optical heart sensor to analyze how blood vessels react to heartbeats.
The algorithm operates in the background over a 30-day period and alerts the user if there are recurring signs of high blood pressure. Incidentally, Apple also notes that if users receive a high blood pressure notification, it is advisable to monitor their blood pressure with a dedicated medical device for seven days.
By providing this information passively and continuously, the watch aims to help users better understand this common health issue and may encourage lifestyle changes or medical follow-up to mitigate long-term health risks.
