Apple Watch Series 8 vs. SE: Which One Is Right for You?
The Series 8’s extra health-tracking features, faster charging and always-on display separate it from the SE.

Deciding on a new Apple Watch can be challenging, especially if you’re choosing between the $399 Apple Watch Series 8 and the $249 Apple Watch SE.
Unless you’re an avid scuba diver or rock climber — or want to look like one — you’re probably not considering the $799 Apple Watch Ultra. The Series 8 and SE are both intended for everyday wearers that want to keep an eye on their health and fitness levels, but don’t need the Ultra’s larger screen, longer battery life and extra features tailored for the outdoors.
Both the Series 8 and SE run on Apple’s WatchOS 9 software, have the company’s newest chip and are among the first to detect car crashes. That’s in addition to the functionality Apple’s watches have offered for years, like the ability to track workouts, detect hard falls and mirror iPhone alerts.
Which one is right for you depends on what you want in a smartwatch. As someone who primarily uses my Apple Watch for logging exercise, viewing notifications and checking the time, there’s little that I missed when switching from the Series 8 to the SE after testing both.
The biggest reason to choose the Series 8 over the SE right now is its extra health-tracking smarts, such as its new wrist temperature measurements, blood oxygen saturation readings and the ability to take an electrocardiogram. The Apple Watch isn’t a medical device and shouldn’t be treated as such. But those who want more data on their cardiac and respiratory health to share with their doctors might find the Series 8 to be the better choice.
I think the Series 8’s main benefits will become more clear over the long term. Temperature sensing is still new, but I like the idea of being able to see how changes in my baseline temperature may correlate with how I’m feeling that day. The Series 8’s ultrawideband chip, which isn’t present in the SE, may also feel more valuable in a future where unlocking your car with your phone or watch is just as common as using Apple Pay at the checkout counter.

A larger screen with an always-on display
If you were to ask me what I’ve missed most about using the Apple Watch SE, it’s the always-on display found on the Series 8 and other flagship Apple Watches since 2019. Without an always-on display, the Apple Watch SE’s screen just turns into a black box on my wrist, which isn’t exactly the most attractive look.
When wearing the Series 8 (or the Series 5, 6 or 7), I can view my watch face anytime without having to raise my wrist or touch the watch. I don’t think the always-on display alone is worth paying an extra $150 if you don’t care about the other health extras that come with the Series 8. But I do wish the always-on display was standard across all Apple Watches at this point.
The Apple Watch Series 8 also has a larger display and comes in 41- and 45-millimeter case sizes, compared to the 40 or 44mm SE. Having a bigger display is nice, but the only thing I missed is the Series 8’s QWERTY keyboard for typing responses to text messages (the Series 7 has this too). On the SE, you can still scribble letters, dictate words or send canned responses, but I like the flexibility of being able to quickly type a couple of words. Those who prefer larger text sizes may also want to choose the Series 8 over the SE.
The Series 8 is also available in a pricier stainless steel finish, and the aluminum version comes in an additional Product Red color option not available on the SE.

More health tracking
Apple’s flagship watches like the Series 8 have evolved into comprehensive health-tracking devices, with the ability to take an ECG from your wrist and monitor blood oxygen levels. The Series 8 and Ultra are the first to get temperature sensors, enabling them to check your wrist temperature overnight and show whether you’ve deviated from your baseline. It takes five nights to set up temperature sensing, since the watch needs enough time to establish your baseline wrist temperature.
Apple says nighttime wrist temperature can be an indicator of overall body temperature, and changes could possibly be caused by illness, jet lag or exercise. Since the Apple Watch doesn’t have a readiness score like Oura or Fitbit, I could see this information being useful for helping me decide whether my body needs extra rest.
I’m hoping Apple weaves wrist temperature readings into new features and insights in the future. Right now, you can see a chart showing how your nighttime temperature readings deviate from your baseline. But it generally seems like it’s up to you to interpret these readings.

The Apple Watch isn’t a medical device and can’t alert you when you’re sick, so it can be hard to know how to use this data. That’s part of the reason why I never check my blood oxygen levels; it’s just another statistic that I’m not sure what to make of. I’ve been wearing the Apple Watch Series 8 consistently for a couple of weeks, but I’m still not sure what to do with this temperature data.
My nighttime wrist temperature is pretty close to my baseline most of the time, but it’s usually a fraction of a degree higher or lower. Sometimes my deviations are as high as 0.37 degrees Fahrenheit above my baseline or 0.55 degrees below the norm. I can’t connect the dots between those deviations and what may have happened to cause them. It’s also difficult to wear the Apple Watch Series 8 consistently overnight since I have to charge it during some evenings.
Still, having another data point like wrist temperature opens up some interesting opportunities for the future. I’m hoping Apple finds new ways to crunch all of these statistics together to enable new insights and actionable advice. Until then, nighttime wrist temperature is yet another metric you can potentially share with your doctor if you’re not feeling well, but it’s difficult to tell how useful it actually is.
For now, the biggest application for the Series 8’s temperature sensing will likely be fertility tracking. Apple says the Series 8 and Ultra can provide retrospective ovulation estimates and improved period tracking, potentially making the Series 8 a better choice for those who are interested in using it for family planning purposes. That information can be helpful because it provides users with data from their own bodies, rather than just making estimates based on the length of their cycle.
«But this actually gives you real life data because the time of ovulation can vary from person to person from month to month,» said Dr. Angela Bianco, MD, director of maternal fetal medicine at the Mount Sinai Health System. «Some people ovulate earlier in their cycles, others ovulate later in their cycles.»
Again, the Apple Watch isn’t a medical device and shouldn’t be treated as such. It also shouldn’t be used for contraception.
«I stress that women who are trying not to get pregnant should not use this because there can be errors in the data,» said Dr. Alexis Melnick, an OBGYN at NewYork-Presbyterian and assistant professor at Weill Cornell Medicine. «And you can have a cycle that is variable that may not follow the regular pattern.»
Apple says data stored in the health app — including female health statistics like ovulation estimates — is encrypted when your iPhone is locked with a passcode, Face ID or Touch ID. The same goes for data backed up to iCloud.
You’ll also want to make sure two-factor authentication is enabled for your iCloud account, which should be turned on by default. This ensures that health data is end-to-end encrypted, meaning Apple cannot read or access your data. To make sure two-factor authentication is on, open the Settings menu on your iPhone, tap your name and choose the Password & Security option.

Other extras, like faster charging and ultrawideband
While the Series 8’s extra health sensors are the biggest reason to potentially choose it over the SE, there are a few other extras to consider. The Series 8 can charge more quickly than the SE, as it inherits the fast-charging capabilities of the Series 6 and 7. The Apple Watch Series 8 charged from 70% to 80% in 10 minutes, while the SE charged from 70% to 77% over the same time period. For each watch, I used the included charging cable and the same power adapter plugged into the same outlet. Both watches have Apple’s new low power mode, which dials back certain features like automatic workout detection to extend battery life.
The Series 8, like the Series 6 and 7, also have Apple’s U1 ultrawideband chip. Ultrawideband is a wireless protocol for proximity sensing that’s become common in new flagship phones and smartwatches. Ultrawideband is primarily used for finding misplaced items and gadgets using Apple’s Find My service, or for unlocking your car with more precision than Bluetooth.
If you have a car that’s compatible with ultrawideband, for example, you can unlock your vehicle automatically as you approach it with your Apple Watch. Ultrawideband is said to be more secure and precise than Bluetooth when functioning as a key, which you can read more about here. It’s a nice perk, but it’s likely not a necessity for everyone. At least not yet.
The bottom line
The Apple Watch Series 8 and SE have a lot in common when it comes to core features and functionality. They can both track workouts, show iPhone notifications, provide high and low heart rate notifications and detect irregular heart rhythms. They also both come with safety features like emergency SOS, fall detection and car crash detection, the latter of which is exclusive to Apple’s 2022 smartwatches. The new Compass app, which includes a new feature to help you retrace your steps, is also coming to both watches as well as the Series 7, Series 6 and first-generation SE.
If you like using Apple Pay or syncing your Apple Watch to the treadmill at your local gym through GymKit, you’ll do just fine with either the new SE or the Series 8. They both have the same processor, support low power mode and run on Apple’s new WatchOS 9 update.
The difference really comes down to health tracking. By choosing the SE, you’ll miss out on the Apple Watch’s ECG app, blood oxygen sensor and new temperature sensor. Whether those features are necessary depends on what you hope to get out of your smartwatch. Do you primarily want to track workouts, or are you looking for deeper health metrics to share with your doctor?
You’ll also get a few perks that make the Series 8 a better iPhone companion, such as a larger always-on display, faster charging and ultrawideband support. Of those features, I personally find the always-on display to be most useful.
Overall, the Series 8 seems poised to become more useful over time, especially after I’ve had more time to test the temperature sensor. Ultrawideband is another feature I’m expecting to become more useful in the long term as using mobile devices as digital keys starts to become more common. But for now, ultrawideband alone shouldn’t be a deciding factor; it’s more about the sum of how all of these parts come together.
The Series 8 is the right option for those who want more health-tracking features and are willing to pay a premium for it. The Apple Watch SE is the best choice for those who are upgrading from an older watch or are buying an Apple Watch for the first time and just want an Apple Watch that feels new and has all of the core features. But if you have a recent Apple Watch like the Series 5, you can probably hold off on upgrading entirely unless you really want Apple’s new health upgrades.

Your Next Yelp Reviews May Include an AI Video — With a Catch
Restaurant rating hub Yelp is now using AI videos to sum up restaurant reviews, but you may want to be careful what you post.

The next time you visit Yelp on your phone to check out reviews on the newest eatery, you may be greeted by an AI-generated video. Yelp is rolling out artificial intelligence videos to Yelp’s home page feed on its iOS app.
The AI videos use large language models to grab text from reviews on an establishment and turn it into an AI-voiced narration (courtesy of ElevenLabs) and captions (courtesy of Amazon Transcribe). Then Yelp uses uploaded photos from user reviews to create a slideshow-like display of what you can eat, drink or dance to.
As far as oversight of these AI videos goes, neither reviewers nor businesses appear to have any say. Companies can’t see the AI videos before they are generated or offer input, and users can’t decline to have their reviews or photos used, which raises a number of privacy questions.
Viewers of the AI videos will have the choice to report a video as inaccurate or containing offensive content. Yelp has said that it will conduct broad audits of the videos, which will be periodically updated for establishments as more reviews and photos come in.
Speaking to The Verge, Yelp CPO Craig Saldanha said that the company wants to create as many videos as possible, although your own activity on Yelp will dictate whether you see the videos and which ones are shown. If we find any way for you to opt out of having your review content — possibly from years past — used in these videos, we’ll be sure to let you know.
Yelp didn’t immediately respond to a request for comment.

You’ll Never Catch Me Running Without These High-Performing Outdoor Headphones
The Shokz OpenFit wireless headphones are the ones I turn to every time I walk or exercise outside.

For anyone who walks, runs, cycles or does just about anything outside on a regular basis, I always give the same piece of advice: Ditch those noise-canceling headphones. Don’t get me wrong. I have a pair of big over-the-ear headphones that have spectacular noise cancellation, and I love them. But when I’m outside — especially if I’m close to fast-moving cars and heavy traffic — I need to be able to hear the world around me and not just my music or whatever podcast I’m bingeing at the moment. In those cases, I want something like the OpenFit true wireless headphones from Shokz.
I love a good pair of headphones, but I don’t love spending a ton of money on them. My threshold is about $100, which is why when all of my cycling friends started raving about bone-conduction headphones a few years back, I was more than a little hesitant because I would probably use them only when working out. However, now is a great time to get in on this innovative headphone technology.
These headphones are designed to be used in places where bone conduction may not be enough and, as a result, I’m rarely seen without mine on. You can grab these headphones at a great price in black and beige, both marked down to $160 right now — a $20 discount off the usual list price.
A week after I picked these up, I was nearly sideswiped by a pickup truck and the only thing that saved me was hearing it come up behind me. There’s a reason these are recommended on our list of the best running headphones you can buy.
If you’re looking for outdoor-friendly workout headphones, my first recommendation is always Shokz, formerly known as Aftershokz. Bone-conduction headphones sit just outside your ear, resting on the bone. Music vibrates through a set of pads into your skull and you hear those sounds as if they’re coming from a speaker a few feet away.
You can hear everything you’re listening to on your phone without interrupting the sounds coming from the rest of the world around you. For cyclists and runners — really anyone who does anything outside — this is a game-changing experience. It’s more accurate and pleasing than traditional headphones with «passthrough mode» and you sacrifice very little in audio quality.
My favorite bone-conduction headphones — and I’ve tried them all — are the OpenRun Pro headphones from Shokz. They’re waterproof (which means they’re easy to clean when I’m all sweaty), the battery lasts me about 7 hours on a charge (perfect for those 70-mile riding days), and they’re comfortable enough that I can wear them all day and not feel them pressing on me. They charge magnetically with a proprietary charger but Shokz includes two cables in the box in case you lose things, as I do.
If these headphones are a little rich for your blood, no worries. Shokz also has cheaper OpenRun and OpenMove bone-conduction headphones with up to 6 hours of battery life and IP55 dust and water resistance. Whether you’re physically active outdoors or you just like exploring new things, I highly recommend giving these headphones a try.

The Shokz OpenMove make a great gift for an outdoor runner

How to Track Your Sun Exposure With This New App
Now in beta, the Sun Day app prompts you on how to prep for being out and about for your specific skin type and location.

Facing down a heat wave this summer? There’s a new beta app for iPhones from the founder of Twitter, Jack Dorsey, that helps you track your exposure to the sun. The Sun Day app is free to testers and contains information like sunrise, sunset and UV index in order to assess your potential burn-limit time and, as the app description says, «track your Vitamin D from the sun.»
Dorsey is currently testing UI updates and a solar noon notification, according to the app notes. In the app, you can describe the type of clothing you’re wearing, such as shorts and T-shirts or swimwear, and your Fitzpatrick skin type, which classifies how quickly you’ll burn.
The iOS app asks permission to connect to some Apple Health data when the app is installed.
Dorsey also recently released Bitchat, a private messaging client that uses Bluetooth as its communication platform. Although it’s meant to be a secure, private app, some users have flagged Bitchat for potential security flaws that are still being tested.
How to test the Sun Day app
If you’ve got an iOS device, download the Sun Day TestFlight app from the App Store and then follow the link to the app for Sun Day to join the beta test.
The effectiveness of an app such as Sun Day depends on giving it accurate information about your skin type and clothing, and while vitamin D levels are one way to gauge UV exposure, it’s not foolproof given that some people also take vitamin D supplements.
«Jack Dorsey’s new app Sun Day is exciting, not to detect vitamin D levels but really to help us understand our UV index which is so important in sun safety,» said Tanya Kormeili, an LA-based dermatologist. «The app does have an interesting promise as far as I am concerned, in that using the UV index can show you the risk for the level of UV exposure.»
The risks of too much sun exposure include sunburns, aging skin and skin cancer. Tracking UV levels is one way to help mitigate those risks.
People tend to think about sun exposure and protections like sunscreen most during the summer, when the sun is strongest and the days are long, and when you’re heading to the beach or out gardening, golfing or otherwise getting in quality sun time. But there is always a risk of sun damage to your skin while you’re outside — year round.
«Sometimes it is hard for patients to be convinced that there can be an excessive UV risk on a cloudy day,» Kormeili says. «The app would provide an objective measure of that UV index and guide you in safer sun practices.»
The dermatologist suggests that Dorsey putting the app out for public consumption without medical experts endorsing it might be a missed opportunity. «I am surprised that they have not involved actual dermatologists in pointing out the true value and limitations of this app,» she said.
