Withings ScanWatch 2 Gets AI-Powered Health Features and Extended Battery Life

This new Withings smartwatch can tell you when you're getting sick

Tech brands are betting big on the ability to spot health strain before symptoms arrive. The latest feature in Withings' newest smartwatch is no different. Withings' Vitality Indicator, available on its new ScanWatch 2, monitors a user's vitals, like their heart rate variability, activity, temperature, oxygen saturation, respiratory rate, and sleep to "pinpoint fatigue causes" and improve them before they worsen, the company announced in its press release. Also: I compared the best smartwatches from Google and Apple - and there's a clear winner The ScanWatch 2 uses predictive AI to monitor minute changes across 35 health parameters and alerts users to signs of potential illness, according to the release. Health tech brands are all-in on their devices' preventative measures these days. "By integrating such innovations into daily routine, we can move from reactive treatment to true prevention, ultimately improving the quality of life," said Éric Carreel, founder and president of Withings, in the release. Also: I've tried 3 different smart rings, but I keep going back to Apple Watch - here's why Vitality Indicator is reminiscent of Oura's Symptom Radar, which monitors similar factors to warn users when they're under strain and should rest. In the past, Symptom Radar has spotted strain when I've been sick. It's a helpful tool I use to check in on my body during sickness and track my recovery post-illness. The new feature is only available to those with a Withings+ membership, which costs $10 a month or $100 annually. Those who purchase Withings' ScanWatch 2 will receive one month of Withings+ free to try the Vitality Indicator. The second-generation smartwatch is available now. Also: 5 Meta Ray-Ban upgrades I want to see on September 17 Earlier this year, Withings unveiled a Cardio Check-Up feature for its membership tier. The feature connects users with a board-certified cardiologist to review their heart data and receive feedback within 24 hours.

Withings adds predictive AI health features to the ScanWatch 2

Withings announced at IFA 2025 today that it's revamping the operating system of its ScanWatch 2 smartwatch. Called HealthSense 4, the update adds new algorithms for 35 health metrics as well as predictive AI-powered alerts when a user's health changes. The ScanWatch 2 also gains two new colors and improved battery life of 35 days -- a roughly five-day increase from the original. In its press release, Withings says the updated algorithms improve activity tracking and step counts. Sleep tracking will also include more accurate breakdowns of sleep stages and respiratory rhythms. Withings Plus members also get a new Vitality Indicator, which adds up various metrics like heart rate variability, activity, body temperature, and blood oxygen saturation to estimate energy levels and fatigue. As for the predictive AI features, users will now get notifications ahead of health events like the beginning of a menstrual cycle or when they may be falling ill. This isn't particularly new for the industry, especially as AI-branded health features are now all the rage. Oura has a similar feature called Symptom Radar, while predictive illness warning features on wearables have been in the works ever since the start of the covid-19 pandemic. It's mostly notable that Withings is a smaller player in the field that has long positioned itself as a more casual lifestyle smartwatch with science-based features. (Though it's been frequently delayed in attempts to get FDA clearance for some of its more advanced health features.) The new ScanWatch 2 colors -- blue and silver -- will be available in the larger 42mm model only. New users will get a one-month free trial of Withings Plus with purchase, which enables access to an AI health assistant, the new Vitality score, and Cardio Check-Up, a feature introduced earlier this year that allows your heart health data to be reviewed by cardiologists. The watches go on sale starting September 5th for $369.95.

Withings Updates ScanWatch 2 With 35-Day Battery Life the Apple Watch Could Only Dream Of

The latest OS version for Withings's smartwatch-in-disguise also brings updates to sleep tracking and health metrics. Withings, which is best known for its smart scales and similar devices, also makes a smartwatch series, the latest of which is the ScanWatch 2. At IFA 2025, the company announced a new blue and silver version of the 42mm model. It also unveiled HealthSense 4, an AI-laden software update that leverages the tech to handle a set of new health- and sleep-tracking features. I grabbed a picture of the ScanWatch 2 while I was there, and now I get the appeal of this watch. If you're not familiar, the ScanWatch's big deal is that they're like smartwatches disguised as regular old analog watches, complete with mechanical time-telling hands and a more standard overall watch face. The screen itself is just a watch face complication -- a tiny circle embedded in the upper part of the screen. The ScanWatch 2 looks nice, and the blue-banded, silver model is no different. In fact, I'm a fan of the blue, if only because it reminds me of the blue suit Adam Sandler wears throughout the movie Punch Drunk Love. (If you haven't seen it and you're scoffing at an Adam Sandler mention in this Very Serious Smartwatch Article, cut it out, and go watch the movie.) This version of the ScanWatch 2 is available now on Withings's website, Amazon, Target, and Best Buy, and costs $369.95. Buyers will get a month of Withings Plus for free. (After that, it's $9.95 a month, or $99.50 per year.) Under the hood, the ScanWatch 2 does a lot of what other, more conspicuous smartwatches do. It takes measurements of things like heart rate and blood oxygen level, or carries out ECG readings to power atrial fibrillation detection. With HealthSense 4, the ScanWatch 2 (and ScanWatch Nova and Nova Brilliant, but not the original ScanWatch or ScanWatch Light) can now track REM sleep and take more accurate measurements of your breathing rhythm while you sleep. Withings says its new algorithms, using data gathered by the smartwatch -- such as heart rate variability, physical activity, body temperature, and respiratory rhythm -- can find possible causes of fatigue, and provide AI-powered recommendations telling users what they might be able to do to feel less tired all the time. These recommendations are collected under what Withings calls the Vitality Indicator, which you need a Withings Plus subscription to access on your phone. Withings product manager Etienne Tregaro walked me through some of the new app features at IFA 2025. The Vitality Indicator screen gives you an overview of your "vitality," which I took to be a sort of shorthand for Withings' AI system's impression of your overall readiness to face a given day. Days of the week at the top of the screen are filled with circles with green outlines that can be anywhere from nonexistent to a complete ring -- the fuller the ring, the less fatigued you are. At the bottom, various boxes tell you where you are for the day in categories like Recovery and Effort. The Withings app also features Withings Intelligence -- a chatbot you can talk to about your health metrics. It can take note of patterns; another Withings representative I spoke with showed me a screen where the chatbot noted he had just lost a little weight, speculated about the causes, and asked if he'd been intentionally trying to lose weight. In theory, it would give him helpful guidance, depending on his answer. The subscription also gives access to AI-powered notifications letting users know when their menstrual cycle is beginning or when the ScanWatch 2 has picked up signs of an infection. The Withings Plus service also comes with Cardio Check-Up, an option to have your cardiovascular data checked by a professional cardiologist, who returns a basic summary of what they saw and recommendations for dealing with issues that may have cropped up. It's a staggering update that leapfrogs over Apple's more passive presentation of health information and more closely mirrors efforts by companies like Samsung to deploy AI, informed by smart wearables data, as a health coach. I worry it could draw certain people further into unhealthy obsessions with constantly tracking and micromanaging their health? I'm not an expert in this; for that, I'd encourage you to read the many articles on the subject. We're riding into a new frontier with generative AI now becoming more deeply enmeshed in smart wearables, and only time will tell. One thing you won't need a subscription for is the battery life improvement that comes with the new HealthSense4 software. Now, the ScanWatch 2 gets 35 days on a charge, which is up from 30 days before, already way more battery life than most standard smartwatches. Although to get there, you'll probably need to turn off a number of the ScanWatch 1's features, like its always-on display or blood oxygen sensor. Tregaro told me Withings managed to add those days by identifying areas it could optimize its code. I asked what your settings would have to look like to actually reach 35 days on a charge, because obviously you can't expect that while using every single feature the ScanWatch 2 offers. He said you'd need to turn off a number of features, including some of the overnight tracking or notifications. Withings, to its credit, has a chart that can tell you which features incur the biggest battery life penalty. Nice to have a guide.

The Withings ScanWatch 2 just got smarter and comes in a new color

Smart rings are becoming the ideal early warning system against getting sick We took the Withing's ScanWatch 2 for a spin last year and found that it was a great wearable if you wanted something that offered a more traditional look. A year later, Withing's is introducing something new, delivering the same watch, but it comes in a new color and delivers more features thanks to a major software update called HealthSense 4. The brand made its announcement during IFA 2025, sharing that its new watch would be available today directly from the Withings website for $370. We imagine that over time, we'll see this watch pop up on Best Buy and Amazon as well. Withings states 'the update introduces advanced algorithms that monitor 35 health parameters with unmatched precision and deliver timely alerts to support energy levels and reduce fatigue.' Something new but familiar Source: Withings To expand on the above, the ScanWatch 2 will be able to better monitor sleep, and for Withings+ members, you'll be able to gain access to a new Vitality Indicator, which will provide 'personalized notifications to help users target and improve the factors that impact their well-being most.' The watch will also utilize AI in order to provide indicators before a health event occurs. We've seen this before with other watches, but it's exciting that Withings will now offer these features on its smartwatches too. The new update for the app makes all the important data you need and want to know about easier to read. The only downside about all of this is that you'll need a paid Withings+ account to access all the best features, which costs $10/month or $99.50/year. As you can imagine, this is quite a large investment considering that you're also going to be paying for the hardware as well. Withings isn't the only brand that does this, but if you're looking to invest in a new smartwatch, there are plenty of other options to go with that won't charge you a monthly service fee. The good news is that the software update won't be exclusive to the ScanWatch 2. If you own the ScanWatch Nova and ScanWatch Nova Brilliant, you'll also be able to download the update to gain new features. If this is something that interests you, we recommend updating your existing Withings watch, or buying the new ScanWatch 2. The new color looks absolutely fantastic.

Withings updates ScanWatch 2 with new colors, health features, and improved battery life

Withings has announced two new colors for its ScanWatch 2, alongside a major software upgrade in the form of HealthSense 4. The hybrid smartwatch, which launched about two years ago, has been well-regarded for blending traditional watch design with advanced health features, but this update takes things a step further. What's happened? Withings has introduced new Silver and Blue color options for the ScanWatch 2 available in a 42mm size. The company has also debuted HealthSense 4 OS, bringing enhanced sleep tracking, heart rate accuracy, and more. The new Vitality Indicator uses AI to analyze key health metrics and deliver personalized insights on energy and wellness. The ScanWatch 2 now offers improved sleep tracking, including REM cycle detection and more accurate monitoring of respiratory rate during sleep. The new updated OS also brings improved menstrual cycle predictions by using overnight body temperature changes, offering more accurate insights for users with irregular cycles or in perimenopause. The TempTech24/7 feature can differentiate body and ambient temperature to help detect early signs of illness like the flu. The smartwatch also continues to deliver on endurance, with battery life now reaching up to 35 days on a single charge. This is important because: Withings continues to offer refinements for its products, appealing to users who care about classic design with modern health features. HealthSense 4 OS raises the bar for wearable health tracking accuracy. The updates ensure the ScanWatch 2 stays competitive against other competitors like Apple, Samsung, and Garmin. Why should I care? Better sleep and heart tracking could make a real difference to your daily health habits. New colors mean more personalization if you're after style as well as substance. Longer battery life paired with smarter health insights makes the ScanWatch 2 a strong all-rounder. OK, what's next? The new Blue and Silver 42mm ScanWatch 2 models are available starting today, September 5, priced at $369.95, and include a 3-month Withings+ subscription. HealthSense 4 OS will ship pre-installed on these new models, though Withings hasn't confirmed when existing users will get the update. Expect rivals in the hybrid smartwatch space to respond with similar improvements like sleep tracking and battery life, as competition ramps up. Withings is expected to expand its ecosystem, offering tighter integration with its scales, blood pressure monitors, and third-party health platforms. The ScanWatch 2 is a solid example of how hybrid smartwatches can balance traditional watch design with meaningful health features. With new colors, updated software, and bundled health tools, it's a solid option for anyone who wants long battery life and reliable tracking without the constant screen time of a full smartwatch.

Withing's newest ScanWatch 2 is a big upgrade for these 2 key reasons | Stuff

The Withings ScanWatch 2 is one of our favourite smartwatches. When we got hands-on time with the watch we said "The ScanWatch 2 takes everything that made the original ScanWatch a success, and adds another capability to its roster." That new capability being temperature sensing. And the latest version brings two big upgrades that make it even better. Rather confusingly, it's still called the ScanWatch 2. Not the ScanWatch 2 SE or the third-generation, just an iteration to the second. It's sure to confuse some users. Still, the extra battery life and deeper insights make it a pretty sizeable update to the tracker. First up, battery life. The newest ScanWatch 2 offers a pretty exceptional 35 days between charges. In a world where most smartwatches run out of juice after a couple of days, Withings is leading the pack. It means you can actually use the ScanWatch 2 to track your sleep every night and monitoring your health 24/7. The other major leap is the new AI-driven health tracking. It's not just about collecting data anymore; Withings is pushing into proper predictive health. The updated HealthSense 4 OS crunches 35 biomarkers and serves up insights that are meant to actually help. There's a shiny new Vitality Indicator that tries to tell you how knackered you are and why. It's even smart enough to throw out alerts when it senses you might be getting ill - or when your period's about to start. Meanwhile, the design remains classically Withings. It gives proper watch vibes with an analogue face - watching the hands fling round when you first set it is always extremely satisfying. This time there's a new 42mm blue and silver version, which keeps things fresh without screaming for attention. It measures just about everything you could want it to. We're talking REM sleep tracking, continuous heart monitoring with PPG sensors, ECG on-demand, temperature readings through something called TempTech 24/7, and automatic activity recognition. Basically, if your body does something, this watch is probably logging it. The app lets you pin what matters to you, and the Withings+ subscription brings in advanced scores, a 24/7 AI assistant, and even the option to have your ECG reviewed by an actual cardiologist. The new ScanWatch 2 is available now on the Withings website for €349.95, and includes a free three-month subscription to Withings+. There's no word on US or UK pricing just yet, but we'll bring you the latest when we can.
