Chance Miller on the Apple Watch Series 12 and Ultra 4→

Apple Watch reviews are out and Chance Miller at 9to5Mac has an excellent, in-depth look at both the Series 12 and Ultra 4. One of the things that Chance points out that might not be immediately obvious to many people is that the inclusion of an always-on chip as part of the S11 system on a chip allows Apple to fill meaningful gaps in both Watches’ data collection:

They will capture your heart rate every five seconds, regardless of whether you’re moving or stationary. Having such frequent and accurate heart rate readings unlocks new levels of data and insight.

When measuring your heart rate once every five minutes while stationary, previous Apple Watch models had an inherent blind spot. They either didn’t capture moments where your heart rate increased while not working out, or they captured one or two arbitrary readings somewhere in the middle of those moments.

That always-on component, combined with the Secure Exclave, is what Apple will also use to keep microphone data private and secure for features like Live Rewind and Siri Recap that are coming later this year.

It was these more frequent heart rate and HRV readings, along with the larger, more accurate sensor on the rear of the Apple Watches, that led me to order an Ultra 4. So I was also glad to see this observation from Chance after his first week with the new Watches:

In my one week with the Apple Watch Series 12 and Apple Watch Ultra 4, I’ve found that added data very insightful. I’m learning more about how little things I do throughout the day impact my heart rate. For example, I can visualize the impact of a late afternoon cup of coffee, or the impact of a stressful moment at work.

That’s the sort of feedback that you can act on and the kind of data that I expect developers will be able to use to make even more meaningful apps across the health and wellness spectrum.

Apple’s Surprise and Shine Event: All the Small Things

An Apple event can only cover so much. Some of the most useful details turn up in the product pages, technical specifications, footnotes, and summary slides after the presentation ends. We’ve collected our favorite smaller changes from yesterday’s Surprise and Shine event below:

iPhone Duo

  • In the hands-on area after Apple’s event, Ben Bajarin reported that the Duo’s hinge crease is barely noticeable, except at specific angles.
  • David Imel was impressed by the matte finish on the Duo.
  • iJustine has an excellent video showing off multitasking using both the outer and inner screen of the Duo.
  • Apple has released a six-video playlist on YouTube and in the Apple Developer app called “Get ready for iPhone Duo” to help get designers up to speed with the phone’s new format. The Human Interface Guidelines have been updated too.
  • The vertical strip along the side of the Duo uses App Control icons for what would be tab bars and nav bars on other devices.
  • For developers, Apple has released five tech talk videos in the Apple Developer app, including “Raise the bar with iPhone Duo.” Additional materials, workshops, and the Xcode 27.1 beta are coming later this month.
  • Continuous Angle API lets developers receive ongoing updates about the Duo’s hinge angle to power interactive effects.
  • Developers who don’t update for the iPhone Duo may have their apps letterboxed.

iPhone 18 Pro and Pro Max

Apple Watch Series 12 and Ultra 4

  • Apple published a study that compares its new Apple Watch Series 12 to other wearables, and the results are impressive.
  • Your Readiness score changes during the day, adjusting based on workouts and changes in your daytime vitals.
  • Audio Intelligence requires more than just a new Apple Watch. Features like Live Rewind and Siri Recap won’t work with the iPhone 16e or iPhone 15 Pro models even though those iPhones support Apple Intelligence.
  • Unsaved Siri Recaps are automatically deleted after seven days, and unless saved, Live Rewind transcripts disappear around 30 seconds after your Watch’s screen dims. Siri Recaps can be edited and exported to other apps like Notes.

Apple Watch Series 12 and Apple Watch Ultra 4: The MacStories Overview

At today’s Surprise and Shine event, Apple introduced the new Apple Watch Series 12 and Apple Watch Ultra 4. Both models build on the devices’ existing designs, adding new health and fitness features as well as what Apple calls Audio Intelligence. The star of the Apple Watch show that powers those features on both models is the brand-new S11 chip. Let’s dig into the details of what the new chip and improved sensors means to both models.

The new Apple Watch Series 12 comes in 42 and 46mm sizes and is equipped with the new S11 chip. Apple says that enables the device to take sixty times the heart rate measurements and 24x HRV readings compared to the Series 11 Watch. More heart rate measurements and HRV readings mean more accurate and meaningful readings; in fact, better than any other wearable on the market, according to Apple. Apple says step tracking is more accurate, too.

The Series 12 has improved sensors, too. There’s a larger, more power-efficient green LED array for measuring your heart rate every five seconds and a Secure Exclave for processing audio privately and securely. On the outside, the Series 12 features Ceramic Shield 2, making it tougher than the Series 11. The case is now IP6X rated for dust and can be used to six meters of depth. Plus, the battery is rated to last 24 hours during normal use and a 15-minute charge will power it sufficiently to last 12 hours.
