Apple Watches already have hypertension notifications, but the Cupertino giant may be working on another blood pressure-related feature that goes further than the alert system available today.
According to Digitimes, Apple has a new high blood pressure notification feature under review by the U.S. Food and Drug Administration. That wording is a little tricky because Apple already released hypertension notifications in September 2025 with watchOS 26. The feature works on Apple Watch Series 9 and later, and Apple Watch Ultra 2 and Watch Ultra 3, in supported regions.
How would blood pressure alerts work?
It is not clear yet how this new blood pressure feature will be different from the one Apple already offers. The report says Apple’s high-end 2026 watch, likely the upcoming Watch Ultra 4, could get a redesign and better health sensors. If true, this would mark the first major health sensor upgrade for the Apple Watch since the Series 9 launched. The new blood pressure feature may depend on that upgraded hardware, but that is only a guess for now.
Apple’s current hypertension notifications are designed more as an early-warning system than a diagnostic tool. The feature tracks trends over a 30-day period and alerts users if it detects signs of chronic high blood pressure. The feature was approved by the FDA back in September 2025. Apple says the feature uses heart sensor data and machine learning, but it does not directly measure blood pressure or replace a medical-grade cuff.
What could come after this?
Apple’s health ambitions do not stop at blood pressure. The company has also been linked to noninvasive blood glucose monitoring for years, a concept that would use light-based sensors to estimate glucose levels without a finger prick or blood sample. But making that accurate on a smartwatch is extremely difficult, so for now, the new blood pressure notifications seem like the more realistic next step for the Apple Watch.
