Apple is testing continuous heart rate tracking for future Apple Watches

The feature could give Apple much richer all-day fitness, recovery, and wellness data

The Apple Watch already keeps a close eye on your heart during workouts, but Apple may be preparing to make that level of monitoring an all-day affair. According to Bloomberg’s latest Power On newsletter, Apple is testing a feature that would let the Watch continuously collect heart rate data throughout the day.

Currently, the sensor works continuously during workouts, while readings outside exercise are taken periodically depending on what you are doing. The new approach would essentially keep workout-style heart rate monitoring running all the time. That could turn out to be a much more useful upgrade than it initially sounds.

Your Apple Watch could understand your entire day better

Continuous monitoring would give Apple a much denser picture of how your heart responds throughout the day, including activity that never gets recorded as an actual workout.

A long walk, a physically demanding day at work, or even several short bursts of activity could all contribute to your cardiovascular load. This is something competitors such as Whoop already do well, using all-day heart rate data to calculate how much strain your body has taken on.

This is one area where Apple has lagged behind some of its rivals. We previously compared the Apple Watch Series 10 with the Pixel Watch 3 and found that Google’s watch measures heart rate once every second throughout the day, while the Apple Watch checks less frequently outside workouts.

Apple may be going after Whoop and Oura

More frequent heart rate data could also give Apple room to build better recovery, stress, and daily wellness metrics. Bloomberg says Apple is separately working on changes to its fitness and health software that would display more wellness information in a style similar to Whoop and Oura.

There is no confirmation that the two projects are directly connected, but they fit together rather neatly. Better wellness insights need better underlying data, and continuous heart rate monitoring would give Apple considerably more of it.

The feature is still being tested, so there is no guarantee it will arrive with the Series 12 or Ultra 4. Battery life could also become a concern, since continuously running the heart rate sensor requires more power. Still, if Apple can make it work without killing battery life, this could make the Watch much better at understanding what your body is doing outside the gym.

EXCLUSIVE: How to ace ‘real’ blood pressure sensing on a watch? Huawei made a big leap and told us the secrets
Blood Pressure Monitoring 1 - Huawei Watch D3 Hands On Early First Impressions

There’s an obvious contradiction at the heart of the Huawei Watch D3. It is thinner, lighter, and more comfortable than its predecessor, yet Huawei has somehow packed even more serious health-monitoring technology into it. Its predecessors, starting with the Watch D, were the first in the industry to measure real blood pressure with a unique micropump system.

The idea is still novel in the industry. Rivals, on the other hand, have shifted to a light-based blood pressure monitoring approach that merely serves as an estimation-based warning system, instead of telling you the real systolic and diastolic values. And with plenty of the usual cautionary messages, of course, and the added hassle of calibration with a real medical-grade cuff. So, when Huawei said the Watch D3 has slimmed down its waistline while getting a sensing upgrade, I was intrigued.

Live Rewind on an Apple Watch

Apple has plenty of shiny numbers to sell the Apple Watch Series 12 and Apple Watch Ultra 4 with. The new Health Sensing System, the Readiness feature, and more frequent HRV readings are just a couple of things that make these a meaningful upgrade. This is especially true for anyone who treats an Apple Watch primarily as a health and fitness device.

Though the feature that caught my eye has almost nothing to do with workouts. Apple calls it Audio Intelligence, and it essentially gives the Watch another way of understanding what is happening around you. The Series 12 and Ultra 4 can recognize important sounds, automatically identify music, recover the last few seconds of speech you failed to catch, and even create summaries of conversations you want to remember later.

Siri is about to hear everything you say, but Apple’s privacy approach has me cautiously on board
Apple's new Audio Intelligence features want to hear almost everything you say. A privacy document released alongside them explains why I am mostly okay with that.
Apple Watch Audio Intelligence features

Apple used its September 2026 launch event to enter a feature category it has mostly avoided until now: ambient listening. Siri Recap, Live Rewind, Music Recognition with Shazam, and Sound Recognition all landed on the Apple Watch Series 12 and Apple Watch Ultra 4. All four depend on the watch microphone picking up sound around you far more often than any previous Apple product has.

Siri Recap listens for conversations throughout your day and turns them into short AI summaries you can check later. Live Rewind is smaller in scope but arguably more useful day-to-day. It transcribes the last 15 seconds of whatever was just said with a double-press of the crown. This is perfect for catching a name, a book title, or directions you missed the first time. Music Recognition uses Shazam to identify songs playing nearby without you lifting a finger, much like Now Playing on Google's Pixel devices. Sound Recognition is a useful accessibility feature that listens for sirens, doorbells, and alarms to alert users who have a hearing impairment.
