I Was Wrong About Workout Buddy, Apple’s AI Coaching Vision Is Just Getting Started

I tested Apple’s new WatchOS 26 feature and spoke with the team behind it. It’s not a full-blown coach yet, but it hints at where Apple may be heading with its AI health strategy.

I wasn’t exactly sold on the idea of having a «buddy» cheering me on during a workout when Apple first announced its Workout Buddy feature in WatchOS 26. The workout partner I had in mind was more of a no-nonsense trainer; someone to push me out of my comfort zone and into peak performance. Apple’s version, instead, is an AI-powered voice that dishes out praise as you run (or as you do any number of activities). But after testing it myself and talking in-depth with Apple about how it works, I’m starting to think the company undersold it on purpose. Workout Buddy is much more than just a hype man, and it represents a crucial turning point in Apple’s health journey.

Workout Buddy turns your Apple Watch into a friendly voice that lauds your achievements during workouts. The WatchOS 26 feature isn’t a full-blown fitness coach that can guide your training plan, but that doesn’t mean Apple isn’t headed there. In fact, Workout Buddy may be the clearest signal yet that Apple is laying the groundwork for something much bigger in terms of fitness tools and AI.

At a time when investors and enthusiasts are critical about the company’s AI efforts, especially compared to competitors like Samsung and Google, Apple has a chance with Workout Buddy to show how its approach is different in a meaningful way. After the lukewarm debut of Apple Intelligence on the iPhone, Workout Buddy is the first time we’re seeing what Apple can do with AI on the watch.

The public beta version of WatchOS 26 is out. I recently tested Workout Buddy in the developer beta of WatchOS 26 and was genuinely surprised by how it made me feel after a walk. I spoke with Jay Blahnik, Apple’s vice president of fitness technologies, and Deidre Caldbeck, senior director of Apple Watch product marketing, to get more clarity around the feature, and unpack the tech and philosophy behind it. And the sense that I got from them is that Apple’s marathon toward personalized, intelligent coaching is only getting started.

Don’t call it a coach… yet

When Apple introduced Workout Buddy at WWDC in June, many Apple Watch fans (including myself) were quick to critique Workout Buddy for being more of a hype man/woman, than a trainer. Compared to competitors such as Fitbit, Garmin and recently Samsung, all of which already offer some form of AI-powered adaptive coaching plan, Workout Buddy with its real-time feedback is more like a cheerleader than a strategist.

It’s easy to overlook what Apple set in motion, by focusing on what Workout Buddy isn’t. The feature is designed to be a motivating presence during your workout, not a drill sergeant. It delivers contextual, personalized encouragement that’s dynamically generated in real time across eight supported workout types: indoor/outdoor walks and runs, outdoor cycling, HIIT, Functional Strength Training and Traditional Strength Training.

«We didn’t want it to be just a pro tool,» Blahnik told me. «We wanted it to be accessible to as many people as possible.»

Workout Buddy requires you wear headphones. I’m a no-frills runner, who’d rather use 2 extra minutes to work out than spend them searching for a headset and choosing the perfect playlist (WatchOS 26 will soon take care of this too). So I wasn’t sold on the idea of using Workout Buddy rather than just tracking my regular pace and heart rate alerts on the wrist with my Apple Watch. And while I’m still not fully onboard with the whole audio gear requirement, I didn’t mind having the Workout Buddy version of my alerts in my ear reminding me that I’d reached my cruising range (that is, my target training zone).

When I launched my first walk workout, I toggled Workout Buddy on and was greeted with a quick summary of my week so far. «This is your fourth walk this week,» it reminded me, and framed it in the context of how close I was to closing my rings. It wasn’t groundbreaking, but it was surprisingly helpful to have that context delivered in a conversational tone, rather than buried in a graph somewhere.

«It’s not a coach, but it is designed to take your data and try to deliver it to you at the right time,» explained Blahnik, «in a way that inspires you and doesn’t get in the way.»

My Workout Buddy did start to get a little too chatty though when I hit some hills during my walk and my heart rate started spiking. Because my HR was constantly teetering above and dipping below my target, the alerts were hitting my ear every few seconds. Luckily, you can tweak or disable HR alerts entirely for each individual workout. My personal sweet spot involved removing just the high HR alert.

A decade of sweat equity and a team of trainers

Workout Buddy was not just Apple’s whimsical creation made to prove that the company can do AI for health and workouts. It’s the result of a decade of fitness data, an inspiring team of Fitness Plus trainers, and the technical lift of Apple Intelligence, Caldbeck told me.

«This was such a great time for it to happen because three things came together,» Caldbeck said. «Ten years of sweat equity, your personal fitness data. Our Fitness Plus trainers. And Apple Intelligence, which gave us the technical capabilities to push it forward.»

I could feel all three in the final product. The voice I heard isn’t just some generic audio prompt, which is what I was used to from these types of features on other devices. It’s a generative model trained on the voices of 28 actual Fitness Plus trainers. The tone, energy, and phrasing feels intentional and personal.

«It’s not a recording,» Caldbeck emphasized. «There was no script. It’s generated in the moment using your workout data and the voice model, and it will sound different every time.»

When I first set up Workout Buddy on my Apple Watch Series 10, I was prompted to choose from one of three distinct voices. They weren’t the tough-love trainer I’d envisioned would whip me into the best shape of my life, but they did sound like someone I’d trust to help me get there. Authoritative, energetic and strangely human. A far cry from the telemarketer-style robo-coach voices I’ve encountered in other programs.

There was a moment when Workout Buddy tipped its hand as something being less than human. It came during a mile-mark check-in, right after I’d crested what I considered a steep hill. It reported my stats: «One mile in, 230 feet of elevation gain.» Then it paused and declared, «That’s a mild elevation gain!» The tone was so emphatic, you’d think I’d just scaled Everest. It wasn’t the message that stood out; it was the delivery. A real person would’ve said «mild» matter of factly. But this was delivered with such over-the-top cheer that it almost felt like sarcasm. But the mismatch between tone and achievement made it sound like my wrist was gently roasting me for doing the bare minimum.

Personalization, with privacy at the core

The personalization isn’t just about your data, it’s about how it’s delivered. Workout Buddy can adapt to your habits, preferences, and even time of day.

«There’s something really remarkable about knowing that whatever they’re saying is unique to that moment, and that you’re not just going to trigger that same sentence on your run again the next day, even if you’ve done the same thing,» said Blahnik.

At the end of the walk, Workout Buddy summarized my stats, distance and calories. And it shared one meaningful nugget: My walk was my fastest pace in four weeks. That hit me harder than I expected. I’ve been coming off a knee injury that’s kept me from running for five weeks, and hearing that small gain was the moment I realized I might be on the mend. It was the kind of contextual insight I’d usually have to dig out on my own, in this case surfaced in my ear without having to think about it.

Under the hood, Apple is balancing Workout Buddy’s intimacy with its long-standing privacy approach. The feature uses a combination of on-device processing (on both your watch and iPhone) and private cloud computation to generate responses in real time. None of your personal fitness data is shared externally.

«We know this is your most personal data,» said Caldbeck. «So we wanted to treat it appropriately, but still give you powerful insights.»

This cautious approach matters. Trust will be the foundation for any future health coaching Apple delivers through AI.

A vision that’s just at the starting line

While Workout Buddy is only available to those with Apple Intelligence-supported iPhones, all Apple Watch users will still benefit from other updates in WatchOS 26. The limitation isn’t about exclusivity, it’s about processing power. Generating real-time, personalized voice feedback requires the kind of on-device performance that current Apple Watch hardware alone can’t handle. At least not yet.

The Apple Watch’s Workout app has the biggest navigation overhaul since it launched in 2015. Core features like interval training and pace alerts, previously buried in menus, are now front and center. Media integration also improved, with dynamic Apple Music suggestions based on your typical workouts that will play as soon as you start your workout.

«We kept our focus on making these features as personal and easy to use as possible,» Blahnik said, «pushing the workout app further than it’s ever been.»

That framing, focused on simplicity, accessibility and personalization, is key to understanding Apple’s strategy. While other companies rush to launch full-blown AI fitness coaches, Apple is taking a more deliberate path: It’s building the infrastructure to handle your data and translate it into meaningful, real-time guidance.

Apple’s been here before with adding native sleep tracking to the Apple Watch. The company waited until it had a clinical reason and subsequently a trustworthy implementation with Sleep Apnea alerts, even while competitors had long offered basic sleep tracking features.

«We almost always start our features to be really welcoming and inclusive and simple to use. We think that there’s a really bright future for where this can go as well,» Blahnik told me.

Apple’s long game

Of course Apple will never tell us where its sights are set next, but you don’t have to be a rocket scientist to draw the connections of where this is all headed.

«When we think about the future, all the ways with which we can push this feature to be even more personalized, we think its really, really exciting,» Blahnik noted.

Workout Buddy may seem lightweight now, but it proves that real time data analysis is already a possibility on the Apple Watch, and it can deliver them in a way that feels motivating and deeply personal. More importantly, it’s testing the waters. It’s accessible, friendly, and non-threatening; something even a beginner might be inclined to use.

It’s setting the stage for what could be next: an AI-powered coach that helps you make sense of all your data beyond just the Workout app to help motivate you and lead you to build healthier habits that will lead to measurable improvements. If Apple plays this right, the long game may actually pay off. Because building trust, delivering real insights and meeting people where they are is how you win the marathon.

An AWS Outage Broke the Internet While You Were Sleeping, and the Trouble Continues

Reddit, Roblox and Ring are just a tiny fraction of the 1,000-plus sites and services that were affected when Amazon Web Services went down, causing a major internet blackout.

The internet kicked off the week the way that many of us often feel like doing: by refusing to go to work. An outage at Amazon Web Services rendered huge portions of the internet unavailable on Monday morning. Sites and services including Snapchat, Fortnite, Venmo, the PlayStation Network and, predictably, Amazon, were unavailable off and on through the start of the day.

The outage began shortly after midnight PT, and took Amazon around 3.5 hours to fully resolve. Social networks and streaming services were among the 1,000-plus companies affected, and critical services such as online banking were also taken down.

The issues seemed to have been largely resolved as the US East Coast was coming online, but spiked again dramatically after 8 a.m. PT as work began on the West Coast.

AWS, a cloud services provider owned by Amazon, props up huge portions of the internet. So when it went down, it took many of the services we know and love with it. As with the Fastly and Crowdstrike outages over the past few years, the AWS outage shows just how much of the internet relies on the same infrastructure — and how quickly our access to the sites and services we rely on can be revoked when something goes wrong.

The reliance on a small number of big companies to underpin the web is akin to putting all of our eggs in a tiny handful of baskets. When it works, it’s great, but only one small thing needs to go wrong for the internet to come to its knees in a matter of minutes.

How widespread was the AWS outage?

Just after midnight PT on Oct. 20, AWS first registered an issue on its service status page, saying it was «investigating increased error rates and latencies for multiple AWS services in the US-East-1 Region.» Around 2 a.m. PT, it said it had identified a potential root cause of the issue. Within half an hour, it had started applying mitigations that were resulting in significant signs of recovery.

«The underlying DNS issue has been fully mitigated, and most AWS Service operations are succeeding normally now,» AWS said at 3.35 a.m. PT. The company didn’t respond to request for further comment beyond pointing us back to the AWS health dashboard.

But as of 8:43 a.m. PT, many services were still impacted, and the AWS status page showed the severity as «degraded.» In a post at that time, AWS noted: «We are throttling requests for new EC2 instance launches to aid recovery and actively working on mitigations.»

Around the time that AWS says it first began noticing error rates, Downdetector saw reports begin to spike across many online services, including banks, airlines and phone carriers. As AWS resolved the issue, some of these reports saw a drop off, whereas others have yet to return to normal. (Disclosure: Downdetector is owned by the same parent company as CNET, Ziff Davis.)

Around 4 a.m. PT, Reddit was still down, while services including Ring, Verizon and YouTube were still seeing a significant number of reported issues. Reddit finally came back online around 4.30 a.m. PT, according to its status page, which was then verified by us.

In total, Downdetector saw over 6.5 million reports, with 1.4 million coming from the US, 800,000 from the UK and the rest largely spread across Australia, Japan, the Netherlands, Germany and France. Over 1,000 companies in total have been affected, Downdetector added.

«This kind of outage, where a foundational internet service brings down a large swath of online services, only happens a handful of times in a year,» Daniel Ramirez, Downdetector by Ookla’s director of product told CNET. «They probably are becoming slightly more frequent as companies are encouraged to completely rely on cloud services and their data architectures are designed to make the most out of a particular cloud platform.»

What caused the AWS outage?

AWS didn’t immediately share full details about what caused the internet to fall off a cliff this morning. Then at 8:43 a.m. PT, it offered this brief description: «The root cause is an underlying internal subsystem responsible for monitoring the health of our network load balancers.»

Earlier in the day it had attributed the outage to a «DNS issue.» DNS stands for the Domain Name System and refers to the service that translates human-readable internet addresses (for example, CNET.com) into machine-readable IP addresses that connect browsers with websites.

When a DNS error occurs, the translation process cannot take place, interrupting the connection. DNS errors are common internet roadblocks, but usually happen on small scale, affecting individual sites or services. But because the use of AWS is so widespread, a DNS error can have equally widespread results.

According to Amazon, the issue is geographically rooted in its US-East-1 region, which refers to an area of North Virginia where many of its data centers are based. It’s a significant location for Amazon, as well as many other internet companies, and it props up services spanning the US and Europe.

«The lesson here is resilience,» said Luke Kehoe, industry analyst at Ookla. «Many organizations still concentrate critical workloads in a single cloud region. Distributing critical apps and data across multiple regions and availability zones can materially reduce the blast radius of future incidents.»

Was the AWS outage caused by a cyberattack?

DNS issues can be caused by malicious actors, but there’s no evidence at this stage to say that this is the case for the AWS outage.

Technical faults can, however, pave the way for hackers to look for and exploit vulnerabilities when companies’ backs are turned and defenses are down, according to Marijus Briedis, CTO at NordVPN. «This is a cybersecurity issue as much as a technical one,» he said in a statement. «True online security isn’t only about keeping hackers out, it’s also about ensuring you can stay connected and protected when systems fail.»

In the hours ahead, people should look out for scammers hoping to take advantage of people’s awareness of the outage, added Briedis. You should be extra wary of phishing attacks and emails telling you to change your password to protect your account.

Take Your Apple Watch Experience to the Next Level With These 8 Tips and Tricks

Get the most out of your Apple Watch with these expert-approved tips.

Apple’s smartwatch lineup is getting better year after year. This year is no exception with the new Apple Watch series 11, Apple Watch SE 3 and the Apple Watch Ultra 3. Whether you’ve got a brand new model to get acquainted with or you’re trying out the new features in WatchOS 26, there are options to keep you productive, become more active and take control of your life. These are the features I love the most.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

Swipe between watch faces (again)

Until WatchOS 10.0, you could swipe from the left or right edge of the screen to switch active watch faces, a great way to quickly go from an elegant workday face to an exercise-focused one, for example. Apple removed that feature, likely because people were accidentally switching faces by brushing the edges of the screen.

However, the regular method involves more steps (touch and hold the face, swipe to change, tap to confirm), and people realized that the occasional surprise watch face change wasn’t really so bad. Therefore, as of version 10.2, including the current WatchOS 26, you can turn the feature on by toggling a setting: Go to Settings > Clock and turn on Swipe to Switch Watch Face.

Stay on top of your heart health with Vitals

Wearing your Apple Watch while sleeping offers a trove of information — and not just about how you slept last night. If you don the timepiece overnight, it tracks a number of health metrics. The Vitals app gathers that data and reports on the previous night’s heart rate, respiration, body temperature (on supported models) and sleep duration. The Vitals app can also show data collected during the previous seven days — tap the small calendar icon in the top-left corner.

If you own a watch model sold before Jan. 29, 2024, you’ll also see a blood oxygen reading. On newer watches in the US, that feature works differently because of an intellectual property fight: The watch’s sensors take a reading, and then send the data to the Health app on your iPhone. You can check it there, but it doesn’t show up in the Vitals app.

How is this helpful? The software builds a baseline of what’s normal for you. When the values stray outside normal ranges, such as irregular heart or respiratory rates, the Vitals app reports them as atypical to alert you. It’s not a medical diagnosis, but it can prompt you to get checked out and catch any troubles early.

Make the Wrist Flick gesture second nature

WatchOS 26 adds a new gesture that has quickly become a favorite. On the Apple Watch Series 9 and later, and the Apple Watch Ultra 2 and Ultra 3, Wrist Flick is a quick motion to dismiss incoming calls, notifications or really anything that pops up on the screen. Wrist Flick joins Double Tap as a way to interact with a watch even if you’re not in a position to tap the screen.

But what I like most about the gesture is that it’s also a shortcut for jumping back to the watch face. For example, when a Live Activity is automatically showing up in the Smart Stack, a quick flick of the wrist hides the stack. Or let’s say you’re configuring a feature in the Settings app that’s buried a few levels deep. You don’t need to repeatedly tap the back (<) button — just flick your wrist.

Make the Smart Stack work for you

The Smart Stack is a place to access quick information that might not fit into what Apple calls a «complication» (the things on the watch face other than the time itself, such as your Activity rings or the current outside temperature). When viewing the clock face, turn the digital crown clockwise or swipe from the bottom of the screen to view a series of tiles that show information such as the weather or suggested photo memories. This turns out to be a great spot for accessing features when you’re using a minimal watch face that has no complications.

Choose which Live Activities appear automatically

The Smart Stack is also where Live Activities appear: If you order a food delivery, for example, the status of the order appears as a tile in the Smart Stack (and on the iPhone lock screen). And because it’s a timely activity, the Smart Stack becomes the main view instead of the watch face.

Some people find that too intrusive. To disable it, on your watch open the Settings app, go to Smart Stack > Live Activities and turn off the Auto-Launch Live Activities option. You can also turn off Allow Live Activities in the same screen if you don’t want them disrupting your watch experience.

Apple’s apps that use Live Activities are listed there if you want to configure the setting per app, such as making active timers appear but not media apps such as Music. For third-party apps, open the Watch app on your iPhone, tap Smart Stack and find the settings there.

Add and pin favorite widgets in the Smart Stack

When the Smart Stack first appeared, its usefulness seemed hit or miss. Since then, Apple seems to have improved the algorithms that determine which widgets appear — instead of it being an annoyance, I find it does a good job of showing me information in context. But you can also pin widgets that will show up every time you open the stack.

For example, I use 10-minute timers for a range of things. Instead of opening the Timers app (via the App list or a complication), I added a single 10-minute timer to the Smart Stack. Here’s how:

View the Smart Stack by turning the Digital Crown or swiping from the bottom of the screen.
Tap the Edit button at the bottom of the stack. (In WatchOS 11, touch and hold the screen to enter the edit mode.)
Tap the + button and scroll to the app you want to include (Timers, in this example).
Tap a tile to add it to the stack; for Timers, there’s a Set Timer 10 minutes option.
If you want it to appear higher or lower in the stack order, drag it up or down.
Tap the checkmark button to accept the change.

The widget appears in the stack but it may get pushed down in favor of other widgets the watch thinks should have priority. In that case, you can pin it to the top of the list: While editing, tap the yellow Pin button. That moves it up but Live Activities can still take precedence.

Use the watch as a flashlight

You’ve probably used the flashlight feature of your phone dozens of times but did you know the Apple Watch can also be a flashlight? Instead of a dedicated LED (which phones also use as a camera flash), the watch’s full screen becomes the light emitter. It’s not as bright as the iPhone’s, nor can you adjust the beam width, but it’s perfectly adequate for moving around in the dark when you don’t want to disturb someone sleeping.

To activate the flashlight, press the side button to view Control Center and then tap the Flashlight button. That makes the entire screen white — turn the Digital Crown to adjust the brightness. It even starts dimmed for a couple of seconds to give you a chance to direct the light away so it doesn’t fry your eyes.

The flashlight also has two other modes: Swipe left to make the white screen flash on a regular cadence or swipe again to make the screen bright red. The flashing version can be especially helpful when you’re walking or running at night to make yourself more visible to vehicles.

Press the Digital Crown to turn off the Flashlight and return to the clock face.

Pause your Exercise rings if you’re traveling or ill

Closing your exercise, movement and standing rings can be great motivation for being more active. Sometimes, though, your body has other plans. Until WatchOS 11, if you became ill or needed to be on a long-haul trip, any streak of closing those rings that you built up would be dashed.

Now, the watch is more forgiving (and practical), letting you pause your rings without disrupting the streak. Open the Activity app and tap the Weekly Summary button in the top-left corner. Scroll all the way to the bottom (take a moment to admire your progress) and tap the Pause Rings button. Or, if you don’t need that extra validation, tap the middle of the rings and then tap Pause Rings. You can choose to pause them for today, until next week or month, or set a custom number of days.

When you’re ready to get back into your activities, go to the same location and tap Resume Rings.

Bypass the countdown to start a workout

Many workouts start with a three-second countdown to prep you to be ready to go. That’s fine and all, but usually when I’m doing an Outdoor Walk workout, for example, my feet are already on the move.

Instead of losing those steps, tap the countdown once to bypass it and get right to the calorie burn.

How to force-quit an app (and why you’d want to)

Don’t forget, the Apple Watch is a small computer on your wrist and every computer will have glitches. Every once in a while, for instance, an app may freeze or behave erratically.

On a Mac or iPhone, it’s easy to force a recalcitrant app to quit and restart, but it’s not as apparent on the Apple Watch. Here’s how:

Double-press the Digital Crown to bring up the list of recent apps.
Scroll to the one you want to quit by turning the crown or dragging with your finger.
Swipe left on the app until you see a large red X button.
Tap the X button to force-quit the app.

Keep in mind this is only for times when an app has actually crashed — as on the iPhone, there’s no benefit to manually quitting apps.

These are some of my favorite Apple Watch tips, but there’s a lot more to the popular smartwatch. Be sure to also check out why the Apple Watch SE 3 could be the sleeper hit of this year’s lineup, and Vanessa Hand Orellana’s visit to the labs where Apple tests how the watches communicate.
