• A report claims a new feature is coming to the Apple Watch Ultra 4
• This could measure your blood pressure using new sensors
• It’s apparently currently awaiting FDA approval

It’s safe to say that the Apple Watch Ultra 3 is a fantastic fitness tracker. Not only is it the best Apple Watch money can buy, but it’s our pick for the best smartwatch on the market, period. And now, it could be about to get even better thanks to a new feature that’s reportedly just around the corner.

According to a report from DigiTimes (via Gadgets & Wearables), the Apple Watch Ultra 4 — set to be unveiled this September — will come with a new feature that can track and measure your blood pressure, giving you timely alerts if something seems to be amiss. DigiTimes believes will lead to a “sharpening [of] the device’s health-management appeal.”

Although this exact feature isn’t here yet, watchOS 26 brought a confusingly similar sounding hypertension alert tool to Apple’s smartwatch range. That uses the Apple Watch’s optical heart sensor to send notifications to your wrist, and DigiTimes states that the new blood pressure feature will work in a comparable manner.

The fact that the tool reported by DigiTimes isn’t here yet is apparently because it is currently undergoing FDA approval. That might mean it needs regulatory clearance before being added to the Apple Watch; if so, gaining that could suggest it’s a more advanced feature that relies on new hardware to provide more accurate metrics.

Many unanswered questions

The idea that this blood pressure system is linked to new hardware makes sense. Apple is rumored to be launching a major design overhaul of the Apple Watch this September, and that might go beyond a mere visual facelift and include new sensors that the blood pressure feature can take advantage of.

Still, this feature might not be as advanced as some people are hoping. Gadgets & Wearables, for instance, suggests that the platform might offer simple notifications rather than detailed systolic and diastolic numbers, implying it is “more like pattern detection than cuff-style measurement.”

Whether or not this feature comes to older Apple Watch models is unknown. Several Watch versions boast optical sensors of the kind used by Apple’s hypertension alerts, which might enable them to work with the new blood pressure tool. Alternatively, Apple may decide that it requires newer hardware found only in more recent devices. We probably won’t know until Apple unveils new Watches later this year.

Aside from this feature, DigiTimes says the Apple Watch Ultra 4 will get a “full redesign” and a ring of eight sensors on the underside of the device, presumably including the optical sensor for blood pressure detection. If you’re after a high-end wearable that looks after your heart, it could be one to watch.
