The Apple Watch Series 12 is the start of a new wearable era

You wouldn’t cognize that the Apple Watch Series 12 is simply a large woody conscionable by looking astatine it. It has the aforesaid design, buttons, sizes, and sensor types arsenic generations of Apple Watches earlier it. But nether the hood, the Series 12 builds successful awesome changes that laic the groundwork for large ideas astir the early of wellness and wearables.

These ideas — and this year’s updates — tin beryllium divided into 2 parts: catching up to the caller roar successful AI wellness and starring the measurement successful AI wearables that aboveground adjuvant accusation based connected your full day. When it comes to the former, Apple is catching up to the remainder of the wearable space, which has eagerly embraced AI arsenic a measurement to make consciousness of each your wellness data. With the latter, Apple is perchance kicking the doorway down connected what’s been a niche, nascent, and precocious problematic market. (Either measurement you portion it, AI is portion of the equation.) Most of the ideas explored pinch the Series 12 aren’t novel, but they haven’t been implemented by a institution pinch Apple’s standard aliases reputation.

After a week pinch the Series 12, I can’t opportunity I person a complete picture. Several of the astir absorbing wellness and AI features aren’t launching until later this twelvemonth and weren’t disposable for review. But moreover without them, the revamped internals supply immoderate meaningful upgrades. So for now, this is simply a look astatine the wellness features that’ll beryllium disposable astatine motorboat — and a preview of the chaotic AI ideas to come.

Two cardinal hardware updates abstracted the Series 12 (and the Ultra 4) from erstwhile Apple Watches. The first is the caller S11 chip, which features a unafraid exclave for microphone information processing connected apical of a faster CPU, GPU, and Neural Engine. There’s besides a wholly redesigned wellness sensor array. This caller array doesn’t needfully seizure new data, but it enables the watch to measurement wellness metrics successful a much frequent, accurate, and power-efficient way. The electrodes that alteration the EKG characteristic are larger to guarantee amended tegument contact, the photodiodes person been reconfigured to seizure reflected ray much efficiently, and larger, little power-hungry optical LEDs are successful spot to radiance ray into the skin.

Together, these hardware upgrades alteration a big of caller package features, including much predominant bosom complaint sampling, a caller readiness score, and a brave caller world of Audio Intelligence, which is what Apple is calling its upcoming suite of AI-powered ambient listening features.

Most notably, the redesigned sensors mean the Series 12 and Ultra 4 are now tin of genuinely continuous bosom complaint monitoring. Previously, to sphere charge, Apple Watches only sampled bosom complaint erstwhile each 5 minutes erstwhile you weren’t moving out. Now, the Series 12 measures bosom complaint each 5 seconds, some astatine remainder and during activities. Other wearable companies person been capable to do this for ages, but this is simply a genuinely adjuvant update for folks who mightiness request to show bosom complaint owed to chronic illnesses.

Apple put retired a achromatic paper comparing really meticulous its continuous bosom complaint monitoring is to a gold-standard Polar H10 thorax strap, arsenic good arsenic competitors for illustration the Pixel Watch 4, Samsung Galaxy Watch 8, Oura Ring 5, and Whoop crossed respective types of workouts and astatine rest. (It’s an absorbing publication for wearable nerds!) I’d request astir 8 arms and legs to replicate this study successful a week, and alas, I’m not an octopus. However, I did deterioration an H10 thorax strap during 2 runs (one dependable authorities and 1 interval run), a walk, and while astatine rest. At each times, the Series 12 was wrong 5 thumps per infinitesimal of the H10. There was a flimsy lag compared to the H10, but successful regular use, you’re not going to announcement that four-second difference.

I’ll proceed testing the Series 12 and Ultra 4 against different devices and crossed activity types, but I’m beautiful assured the Apple Watch is now successful statement pinch galore different celebrated wearables.

The S11’s effect was besides noticeable successful testing. Siri AI queries are faster connected the Series 12 than my Ultra 3. You still mightiness tally into latency arsenic Siri “thinks,” but not arsenic much. If you want much in-depth thoughts astir Siri connected the wrist, my sentiment hasn’t changed from my watchOS 27 preview. In a nutshell, this is the astir tin wrist machine Apple’s made, and adding a azygous pinch motion to prime items makes one-handed power the champion it’s ever been.

I didn’t announcement a antagonistic effect to artillery life from continuous bosom complaint tracking. People will gripe that the Series 12 doesn’t person multi-day artillery and sticks to the Series 11’s 24-hour artillery estimate. But for illustration past year, I support that faster charging is simply a good capable solution. In a 20-minute charging test, I went from 20 to 64 percent battery. Yes, that does mean charging regular successful small spurts, but I’ve yet to person the watch dice connected me. I vehemently judge everyone needs to fto their wrists respire daily, and showering is the perfect clip to spell watchless. You’ll past 20 to 30 minutes of nary data.

All this caller hardware paves the measurement for a overmuch much robust wellness search experience. That’s astir apt why, later this fall, we’re getting a new, redesigned Health app. From the demos I’ve seen, it’s going to beryllium a melodramatic change. There’ll beryllium AI-powered insights, a longevity tab that includes a Health Age score, VO2 max appraisal tests utilizing your phone’s camera, and moreover the expertise to bid a humor sheet done Quest Diagnostics for $119. The redesigned app is presently disposable successful the latest iOS 27 developer beta, and I’ll springiness my early impressions connected that soon. However, successful this reappraisal I’m only going to talk astir what’s disposable to everyone astatine launch.

The large update fresh coming is Apple’s return connected a readiness score. Readiness scores were popularized ages agone by Fitbit, Oura, and Whoop and are meant to beryllium a digestible gauge of really good you’ve recovered from physiological stress. In essence, really “ready” you are to activity retired again.

Apple assesses “readiness” done a operation of overnight, daytime, and play metrics for illustration activity, slumber score, and overnight vitals encompassing resting bosom rate, respiratory rate, wrist temperature, and a caller metric called betterment bosom complaint variability (HRV). You mightiness deliberation — wait, my Apple Watch has been capable to measurement HRV for years. You’d beryllium correct. This caller betterment HRV metric uses a different look and is enabled by the truth that the watch’s updated sensor array tin now return any HRV measurement overmuch much frequently. Whereas “regular” HRV is meant to beryllium a longitudinal look astatine your wide accent and cardiovascular health, Apple uses betterment HRV arsenic a gauge of your daily, short-term strain. (And because this is enabled by the caller array, it does mean readiness requires astatine slightest a Series 12 aliases Ultra 4.)

It takes a basking infinitesimal to make the people — 7 nights of slumber successful which you get astatine slightest 4 hours of rest. On the eighth day, you aftermath up pinch a people from 0 to 10. A 0 to 1 intends you should recover, a 2 to 4 intends “pace yourself,” 5 to 7 is simply a benign “ready,” and thing 8 and supra is simply a awesome to “go for it.” My week of superior sleeping and accuracy testing culminated successful a readiness people of 7.

I’m of the sentiment that group intuitively cognize whether they consciousness for illustration moving retired aliases not. This is simply a characteristic that’s astir useful for stubborn athletes who overtrain and request a reminder to not pain themselves out. I admit this isn’t a fixed score. A powerful nap aliases an other difficult workout could origin your readiness people to emergence aliases autumn during the day. For the Garmin nerds, I’d opportunity it’s for illustration a operation of Body Battery (which estimates your power levels successful existent time) and accepted readiness scores. Given that wearable companies support pumping retired caller metrics, I admit that Apple’s chosen to consolidate what could’ve been aggregate information points into one.

After WWDC, I wrote that I was relieved Apple wasn’t diving full-on into AI wellness coaching features. I person to eat my words a teeny bit, considering Apple is intelligibly starting to incorporated immoderate — though not each — of the AI wellness trends I’ve seen cropping up complete the past 2 years. So far, I deliberation Apple is cautiously weighing what trends to hop connected and which ones to avoid. That’s a smart semipermanent move. But I’m still relieved Siri AI isn’t playing a larger portion conscionable yet.

Aside from faster, much power-efficient performance, the S11 spot besides enables the astir astonishing update to the Series 12: ambient listening. That expertise is what enables Audio Intelligence, a suite of 4 features that fundamentally move the microphone into a perchance powerful AI tool.

The 2 flashiest features are Live Rewind and Siri Recap. The erstwhile lets you publication a short transcript connected your wrist of the past 15 seconds, while the second is simply a high-level summary of conversations you’ve had during the day. In this summertime of nationalist backlash against alleged pervert glasses and Flock cameras, these 2 features understandably stirred up a batch of interest and emotion connected societal media. That said, I wasn’t capable to trial these features because they’re not disposable yet. They’ll get later this twelvemonth via a package update.

What was disposable to trial was faster Shazam for identifying songs and sound nickname for alerting you of perchance urgent adjacent noises. Both of these features require you to opt successful and are not turned connected by default. If you do move connected euphony detection, it is extremely fast. You tin conscionable pinchy pinch to bring up the Smart Stack, AI will aboveground the Shazam widget, and roar — there’s the song, correctly identified. (I did travel it up a teensy spot by quickly switching betwixt songs, but that’s not apt to hap successful an integrated Shazam experience.)

Testing sound recognition, which is an accessibility characteristic for the deaf aliases difficult of hearing, was little conclusive. It’s designed to emblem connected the wrist erstwhile sounds for illustration doorbells, alarms, aliases sirens spell off. Ironically, I haven’t had my doorbell ringing this past week, but I did propulsion up respective YouTube videos of doorbell chimes astatine various volumes. None triggered the feature. I deliberation that’s a bully thing. In my erstwhile tests pinch different ambient listening AI wearables, they struggled to separate betwixt “real” sounds and TV shows. The past point you want is simply a fictional doorbell triggering an annoying, real-life alert. A blaring motortruck horn besides didn’t trigger the feature, arsenic it wasn’t a siren. I’ve asked Apple whether there’s circumstantial tuning to minimize mendacious positives, but I haven’t heard backmost yet.

I’ll do a deeper dive into Audio Intelligence erstwhile the full suite of features is available. But to me, it’s clear that Apple has been taking notes astir the burgeoning AI wearable space. It’s a deliberate prime to present these features connected the Apple Watch, an already acquainted and beloved device. As different tech companies woody pinch surveillance and harassment concerns, Apple’s published a privateness achromatic insubstantial and support documents to position itself arsenic a leader trying to group a caller standard. If successful pinch the public, it’s not a agelong to spot really Apple mightiness see these kinds of features connected a brace of smart glasses or, perhaps, AirPods pinch camera sensors. If not, it’s nary large miss. The Apple Watch is already a useful, sometimes lifesaving instrumentality without Audio Intelligence.

The astir interesting, and possibly consequential, portion of this rollout is that it comes from Apple, a wildly successful tech institution pinch the strongest privateness estimation successful Silicon Valley. If it can’t make this class of instrumentality work, that surely doesn’t bode good for AI wearables arsenic a whole.

In galore ways, this is an incomplete Series 12 review. Judging solely connected what’s disposable today, this is simply a straightforward hardware upgrade that closes the spread betwixt Apple and the standout perks of much niche rivals for illustration Whoop and Oura.

For those pondering upgrades, Apple has laid a beardown instauration pinch its hardware for immoderate eager features down the road. I’d understand if you person qualms astir Audio Intelligence and privacy, and to those folks: I’ll punctual you that past year’s models are still great, astir apt disposable connected sale, and don’t travel pinch arsenic galore privateness questions.

Otherwise, the Series 12 is simply a worthy upgrade if you’re sporting a Series 6 aliases earlier. Series 7 and 8 users should measurement really overmuch they attraction astir AI features versus their device’s existent artillery life, arsenic watchOS 26 will proceed to get information updates. Series 9 and later don’t request to upgrade unless, perhaps, they person a chronic unwellness that could use from the improved continuous bosom complaint monitoring. The excellent SE 3 remains my proposal for smartwatch newbies who conscionable want a basal fittingness tracker. I’ll person an Ultra 4-specific reappraisal retired soon, but I tin already show you that’s for folks who for illustration large screens, amended artillery life, and aspire to the outdoor life.

If the Series 12 only had a caller sensor array, updated Health app, and a much useful Siri connected the wrist, that’d beryllium a important update and triumph connected its own. But there’s a batch much present that’s going to alteration this merchandise successful immoderate basal ways complete the adjacent fewer months. I person a emotion that Apple’s ambitions for the watch don’t extremity pinch wellness tracking.
