French well being tech model Withings has been across the block and a few. These days it provides a spread of health wearables and screens. It was additionally an early mover in good scales and is continuous to push the envelope right here — with Body Scan, its present flagship scale (or “connected health station” as its advertising and marketing places it).
As the title suggests this top-of-the-range good scale goes far past merely conserving tabs in your weight. The product serves up a spread of well being assessments — enabled by a {hardware} twist evident within the product’s tagline (“get a handle on your health”); a reference to an built-in bar that pulls out of the ground unit. This permits the machine to get a deeper have a look at what’s occurring along with your physique because of a combo of pores and skin touch-points and embedded sensors.
Withings has engineered Body Scan to offer a set of assessments that deepen the consumer’s understanding of their cardiovascular well being, particularly, together with scoring how properly blood vessels are functioning. The product seeks to make use of quite a lot of data-points to affix the dots between the consumer’s weight, coronary heart well being and life-style — giving a sign of whether or not the latter is properly balanced and supporting them to fulfill their private health objectives (and/or shrink potential well being dangers) or not.
The pricing for Body Scan displays this broad “health check-up” pitch — with the product retailing at $399.95 within the US; €400 within the EU; and £349.95 within the UK.
Main options
The scale comprises 4 weight sensors that may present a “precise” weight measurement to inside 50g, per Withings. The sensitivity means it’s best to anticipate to see fluctuations within the weight measure everyday — and even throughout a single day. Although Withings recommends utilizing the size as soon as per day (and, ideally, on the similar time of day and similar situation; i.e. not having eaten a meal lately and many others) to assist with benchmarking and monitoring adjustments over time.
As properly as charting weight adjustments, the app calculates and charts Body Mass Index (BMI), Basal Metabolic Rate (BMR) and estimates what it dubs your “Metabolic age” — the latter, which may be about the identical as your precise age, or decrease (higher) or increased (much less good), is calculated by evaluating weight and physique composition to different customers with comparable profiles (i.e. weight, intercourse, age).
While the next BMR, which is indicative of upper muscle and lean mass, will — sometimes — end in a decrease Metabolic age. Eating extra nutrient dense meals and including resistance coaching to your train regime might help enhance BMR so the measure can present a wider evaluation of how wholesome, or in any other case, the consumer’s life-style.
To measure physique composition (muscle, fats, bone mass and many others) the Body Scan makes use of a method referred to as multifrequency Bioelectrical Impedance Analysis (BIA).
This works by sending a tiny, imperceptible electrical present by the physique. The scale’s built-in deal with has a collection of steel plates on it which must be in touch along with your palms and thumbs throughout the scanning course of because of this. The app can visualize the outcomes on a dummy avatar. Additionally, it charts your physique composition information, additionally breaking out Lean Mass, Water Mass and Visceral Fat Index in separate graphs.
Withings depends on sending a tiny electrical cost by the consumer’s physique to measure arterial stiffness, too. It does this by monitoring the time it takes for a wave that’s created within the blood as the center beats to reach on the foot — a measure referred to as Pulse Wave Velocity (PWV). The app information and tracks a velocity worth for PWV, to watch adjustments over time. It additionally supplies a comparative score for “Vascular Age” (vs the consumer’s age) — charting whether or not it falls within the regular, not regular or optimum vary.
Another flagship characteristic of Body Scan — one among two that’s been accepted by medical machine regulators within the US and Europe — is a 6-Lead Electrocardiogram (ECG) which might detect AFib (aka atrial fibrillation), a typical cardiac rhythm disturbance that may trigger stroke and coronary heart failure.
This characteristic will already be acquainted to customers of wearables just like the Apple Watch — one other shopper tech machine that may detect and monitor AFib. It’s extra novel to see it on a sensible scale. That mentioned, to take this measure requires standing as nonetheless as potential for 30 second, and in a considerably awkward posture to make sure no skin-to-skin contact, so it’s not essentially the most comfy consumer expertise for acquiring an ECG.
Both the US and EU variations of Body Scan have the medically cleared the ECG characteristic. There are another variations between the gadgets it’s promoting over the pond and in Europe, although. Principally: The US model of Body Scan consists of an Electrodermal Activity (EDA) Score. (Per Withings, this measures and assesses sweat gland exercise within the foot which it says can present perception about an individual’s stress ranges, weight loss program and general well being. But we weren’t capable of check this.)
The EU model of the product, which is the {hardware} TechCrunch was testing for this evaluate, doesn’t have the EDA characteristic. Instead it might calculate what Withings refers to as a “Nerve Health Score”. This is supposed to offer a measure of the consumer’s nerve well being to detect indicators of peripheral autonomic neuropathies (or harm in small nerves), which generally is a complication of continual circumstances like diabetes.
Per Withings, the Nerve Score works by monitoring sweat gland exercise by stimulating nerves within the consumer’s ft — once more by making use of a low voltage by the physique, through the glass plate and the conductive electrodes on the deal with. It then estimates the response of the sweat glands within the ft by measuring the extent of conductance (which is dependent upon the variety of chloride ions that react with the electrodes). A decrease rating signifies the presence of low sweat operate which may be an indication of peripheral autonomic neuropathy. As with the ECG, the Nerve Score has been cleared with medical machine regulators in Europe.
How Body Scan works
Withings has designed the product to take all potential measurements each time you seize the deal with and step as much as weight your self — so consider it like a each day well being check-in. That mentioned, in apply, it received’t at all times efficiently file all of the data-points every time you employ it, as we talk about in additional element beneath. So Withings’ imaginative and prescient of a seamless single scan to seize the whole lot stays a piece in progress.
The primary physique scanning course of is as follows: You step (naked foot) on the tempered glass scale — ideally the identical time each day — rigorously positioning your ft on the middle of the striped mirror markings. You additionally want to know the deal with and carry it up, pulling on its retractable wire to achieve standing top and ensuring your palms and thumbs make contact with steel patches on the underside and prime of the bar respectively. Stepping on the size prompts it. So as soon as in place you merely stand nonetheless and look forward to the machine to do its thang.
(NB: Withings does additionally suggest first wiping the glass and deal with with a heat damp material to enhance conductivity. However we discovered doing this typically appeared to impair sure recordings, such because the Nerve Score, so it’s most likely price testing it dry too to see for those who get extra success.)
Throughout the scanning course of — which might take a minute or so — it is advisable to stand nonetheless, adopting a posture that avoids the pores and skin in your legs and arms making contact. So it’s a bit (chicken-wing) awkward.
The coloration display on the size shows particulars of every check because it’s being undertaken. Typically adopted by a quick outcome (until you’ve opted out of seeing your weight displayed within the app). Otherwise it’ll throw up an error if it fails to file the measurement.
As famous above, monitoring your metrics over time occurs within the companion Withings app — which provides far richer information visualization — however the display on the size will present a small plot of any current weight adjustments while you weigh in. It additionally, by default, shows native climate and air high quality information.
At the tip of the scanning course of the size indicators off with a wave emoji — and a cheery “see you soon!” — to verify it’s run by all of the exams. So for those who’re used to weighing your self comparatively sometimes you’ll discover Body Scan encourages a way more common scale-stepping cadence.
Withings’ huge concept is to make use of a well-known protocol (stepping on a scale) to nudge customers into common monitoring of a spread of well being metics — from their standing coronary heart charge and different indicators of coronary heart well being; to visceral fats and physique composition; to nerve and arterial well being — by bundling a number of exams right into a single standing scan.
Mixed outcomes
While among the metrics the Body Scan captures are cleared by medical machine regulators in Europe or within the US — which means Withings introduced proof of the security and efficacy of those measurements — different information factors the machine captures haven’t gone by that means of exterior scrutiny. So the metrics and scores it generates should not universally benchmarked. Which means accuracy is a blended bag.
This was evident throughout testing. We discovered among the measurements, resembling for physique composition, appeared considerably unrealistic — resembling recording extraordinarily low (together with typically single digit) fats mass figures. But, on the flip aspect, the size appeared to accurately establish areas of upper vs decrease muscle mass (for e.g., my arms and torso fell within the highest muscle vary whereas leg muscle was barely decrease which is what I’d have anticipated for somebody who trains as a climber).
As with most shopper well being tech, a superb rule is to to not get too hung up on any single recorded data-point — particularly people who haven’t been accepted by regulators. You can nonetheless get utility out of those merchandise by utilizing them as trackers to keep watch over whether or not your well being tendencies are headed in a constructive (or not so nice) course.
The comparative ranges Withings’ app supplies are helpful on this regard — providing an at-a-glance view to know whether or not you’re in or exterior a standard vary vs different customers such as you. But how correct particular, non-regulated measures it takes is up for debate.

Withings informed us it has huge plans for Body Scan — together with a plan to develop variations of the product for B2B customers, so promoting {hardware} to healthcare suppliers (which might require extra common consideration to accuracy). The firm additionally talks by way of Body Scan being the “new hardware base” for the subsequent decade or two of its well being merchandise. So it definitely intends this each day stand-to-scan idea to face (ha!) the check of time.
At the identical time, it’s nonetheless early days for the product, which launched in Europe on the finish of final 12 months however solely obtained FDA approval for the ECG characteristic this summer time — forward of a fall US launch. And, throughout testing, we discovered a good quantity of UI tough edges and UX friction getting in the way in which of its ambition to serve up easy well being monitoring. So our basic view is that the Body Scan has promise — however Withings has extra work to do to finesse the software program.
We additionally had some points getting the multi-user characteristic to work. Withings provides a few methods to arrange your scale for a number of customers however — you guessed it — neither is properly defined. The first technique we tried, which concerned sending a hyperlink to the opposite particular person, did not work. But we did handle to get it arrange utilizing the opposite technique. This second consumer was then capable of get their well being information flowing to the Withings app on their very own telephone.
The scale can robotically detect totally different customers (presumably by weight) and it did this accurately throughout testing with the 2 customers we had set it up for with out us needing to manually point out the right consumer profile. But when you’ve got quite a lot of members of the family who’ve an identical weight it may not carry out the detection so properly. In which case you’ll must shift your weight to at least one or different foot (i.e. left or proper foot) to pick the best profile firstly of the scanning course of.
We didn’t have an opportunity to check that nevertheless it seems prefer it may be fiddly as there’s not an enormous period of time to carry out this foot balancing trick earlier than the machine begins scanning.
Work in progress?
Our expertise with Body Scan obtained off to an inauspicious begin after a collection of irritating transport issues (apparently associated to a poor alternative of native supply accomplice); after which as a result of we had been shipped a scale with some type of account syncing fault — which means each time we stepped again on it the display requested to be paired with the app once more. This doom loop meant it wasn’t performing key measurements.
After we reported the problem, Withings shipped a second unit that didn’t have the identical drawback. So we will solely assume unit 1 was a dud. The second unit accurately paired with the app and we noticed information began flowing. But then one other subject popped up as we seen some lacking measurements with this unit too.
The fundamental drawback we bumped into at this level gave the impression to be associated to key utilization data not being clearly introduced within the app/communicated to the consumer.
The very first thing to notice is there’s a layer of (needed) complexity connected to the Body Scan recording sure measurements (i.e. these cleared by medical regulators) because the consumer should learn a tutorial and conform to T&Cs earlier than these options may be activated. So until/till you’ve finished that you simply’re not going to see the size performing an ECG for instance.
That opt-in step shouldn’t be a problem. However it’s extra convoluted than it needs to be as a result of Withings’ app design is complicated and the UX typically lacks clear sign-posting for the consumer — who’s left to faucet round a number of menus and and sub-menus, with key choices tucked away in laborious to find locations.
This drawback could possibly be fastened with higher app design and steerage. As it stands, the app drops in with sporadic (and slightly cryptic) pings — through a notifications feed which additionally blends in gamification-style nudges meant to drive utilization (so extra akin to spam). This unhelpful mixing of essential notifications and random congratulations (resembling for weighing your self X variety of occasions) means key information can get misplaced within the noise.
The upshot of this was we had been left questioning, for days, why the ECG and PWV measurements weren’t being recorded throughout our each day standing scan. Eventually we seen a notification pop up within the feed saying no PWV information had been collected. This linked to a basic article with recommendations on the way to “improve the reliability of your measurement”. But the app nonetheless didn’t be part of the dots for us and supply the plain troubleshooting answer (i.e. that the tutorial and T&Cs wanted to be reviewed).
This was truly a bit bizarre as we had been fairly certain we’d already reviewed the whole lot on arrange. But, for no matter cause, the app thought we had not.
At this level the app was additionally failing to show a bunch of information within the weight tab — initially, we couldn’t see any BMI information or Metabolic age, whereas BMR was typically displayed, typically not — however after we’d made a second go over the aforementioned tutorials and T&Cs these lacking fields instantly obtained populated.
Just discovering the place the tutorials had been tucked away within the app’s a number of menus, after their preliminary surfacing throughout onboarding, was one other pointless app navigation problem. Eventually we tracked down all these excellent steps and obtained (most of) the lacking metrics up and working. But higher app and UX design would keep away from such clearly irritating pitfalls.
That was not the tip of the problems, although. Data show has continued to be a bit patchy — such because the app displaying just some physique segments within the visible explorer. (Currently it’s exhibiting fats mass for torso and legs however not arms; and muscle mass for arms and torso however not legs, for instance. With no rationalization for this sudden phantom information limbs subject).
A extra main drawback with the European model of the product is that it’s very laborious to file a “confirmed” Nerve Health Score.
The app seems to have recorded just one single confirmed rating for this throughout weeks of testing (circa 30 each day scans). Nor does it make it clear it hasn’t recorded this information. You have to note that the chart in query is displaying a tiny gray diamond, slightly than a tiny blue circle. (The gray diamond signifies a “predicted” worth, a confirmed worth is a tiny circle.)
It’s not clear how correct the expected Nerve Score is vs a confirmed measurement. But textual content underneath this chart urges customers to “weigh in as often as possible to get a confirmed score in 24 days” — so infrequency in acquiring confirmed information does appear to be inevitable.
Asked about this, Withings admitted the Nerve Score measurement is delicate. Because it’s one of many “medically-approved” options the corporate informed us the algorithm must have a excessive stage of confidence the rating is right so as to show it as confirmed. But if the measure is so delicate you’ll be able to barely get a rating that’s not a tremendous product expertise.
Elsewhere, we’ve additionally discovered the size continues throwing up fairly common errors throughout the scanning course of for different measurements — most frequently failing to file PWV or coronary heart charge.
The display will simply show the phrase “error” when this occurs. And the app doesn’t provide any rapid suggestions on what might need gone incorrect. So, once more, troubleshooting communication is a weak level.
Withings’ spokesman informed us such errors may happen as a result of we moved a bit throughout the scanning course of. Or that we had been standing on the incorrect little bit of the striped sample on the glass. But with such an absence of clear exposition to troubleshoot issues customers aren’t able to know the way to right points for his or her subsequent scan.
It’s not even totally clear on which little bit of the striped space on the size you’re imagined to place your foot. (We had been supplied with some conflicting information about this.) So Withings has work to do to iron out communications wrinkles and enhance primary product usability.
Another subject we had — at the least initially — was we discovered the app to be fairly noisy. All types of (non-essential) notifications and nudges obtained fired at us within the early days, together with some kind of digital badges (seemingly encouraging you to get extra lively), and pushes to join a comparative leaderboard of weekly lively challenges.
The app additionally packs in a bunch of articles with extra information/context in regards to the totally different well being measures. And has a complete part put aside for a Withings+ subscription — a paid providing that’s meant for customers who need assist getting their metrics trending in the best course by receiving health and life-style recommendation.
There’s most likely a bunch of fine (and helpful) stuff right here nevertheless it felt like overload as we had been nonetheless making an attempt to become familiar with primary troubleshooting and information show points.
More considerate app design would take a extra cautious, staggered strategy to all this messaging and search to not bombard the consumer with a lot content material from the get go. Not least as a result of the core metrics that Body Scan supplies, as soon as it’s up and scanning correctly, is already a number of information to digest.
After a number of weeks of wrangling with the vagaries of the UX and entering into the behavior of often weighing in we did begin to really feel the Body Scan entering into extra of a stride. And we may definitely see the worth in taking a minute or so out of your morning so the app can seize your well being snapshot.
Tracking adjustments to the well being metrics Body Scan measures or estimates provides clear utility for anybody desirous about getting or staying match and wholesome — given the give attention to physique comp. It’s more likely to be a useful adjunct for athletes doing macro monitoring with the aim of boosting their muscle mass, say. While the center measures and a focus to blood vessel and nerve well being is more likely to be particularly fascinating to individuals with particular well being issues, resembling pre-diabetes or excessive ldl cholesterol, who additionally could have a medical want to watch (and ideally cut back) their weight.
At the identical time, measurement sensitivities and scanning errors look like an unavoidable aspect of the Body Scan product expertise. At least for now. Recorded metrics can even fluctuate fairly a bit (with out, essentially, an apparent trigger for this to occur). Which raises the specter of inaccurate well being quantifications — definitely for the non-regulated options.
Albeit, that mentioned, some sensitivity in measurements does appear to be a organic characteristic, not a bug, if we will put it that means. (For instance, PVW may be delicate to emphasize. So for those who’re going by some worrying stuff you shouldn’t be stunned to see this worth tick up a bit. And throughout testing we did discover some slight fluctuations that perhaps correlated with durations of upper and decrease stress.)
Of course it goes with out saying that utilizing a shopper product to carry out a “health check” isn’t an alternative choice to getting correctly checked out by your physician for those who do have any well being issues. At greatest, the Body Scan may provide a little bit of reassurance between skilled examine ups.
For individuals with an lively give attention to sustaining and/or bettering health Withings’ top-of-the-range good scale is an fascinating — if slightly costly — device to help coaching by serving to quantify outcomes. A private coach in a field, kind factor — although you do should do the heavy lifting of decoding the information within the context of your actions. So you’ll need to work to get essentially the most out of the product. (Or else shell out for Withings’ “health improvement” subscription product, Withings+, to get extra hand holding.)
When it involves extra basic shoppers, who should not used to paying such shut consideration to what’s occurring with their physique, they could really feel a bit uncomfortable to see stark in-app descriptors like “losing muscle” or “gaining fat”. But there’s scope to customise what the app reveals you, to a level.
Withing has configured a couple of totally different modes to assist adapt the product to totally different use-cases. For occasion there’s an athletic mode for extra professional sporty varieties with very low resting coronary heart charges; and a being pregnant mode. At onboarding, it additionally helps you to set a basic weight aim — e.g. shedding, gaining or stabilizing weight; or gaining muscle mass or shedding fats mass — which is able to set the tone of a few of these in-app notifications. As famous above you can even flip off seeing the size weight seem on display while you weigh your self to keep away from having to see a probably unfavourable set off on the display at every each day weigh in.
But there’s no getting away from the truth that among the scores and stage of obvious element the Body Scan can floor could possibly be a little bit of a shock.
Verdict
As ever, with regards to related well being tech, a lot of the data-points you’re paying for shouldn’t be handled as gospel reality however slightly as a springboard for taking constructive motion to get your scores trending in the best course. That’s additionally typically the case with Body Scan. But the one or two options cleared by medical regulators needs to be given extra weight — so if, for instance, you get a notification the size has it’s picked up indicators of AFib do after all deal with the sign critically and e-book an appointment along with your physician ASAP. (The app handily helps you to share a well being report along with your clinician for that kind of goal.)
Zooming out, the recipe for good well being isn’t some type of uncommon secret — everyone knows we needs to be making an attempt to keep away from stress, getting higher high quality sleep, maintaining a healthy diet complete meals and taking sufficient train — however good tech that may ship personalised nudges to encourage constructive life-style decisions may be very useful at motivating us to shoot nearer to the perfect. Tracking bodily adjustments over time will also be useful to search out the best combo of life-style actions that works for you, whether or not you’re coaching for a marathon or simply making an attempt to get motivated to get off the couch extra usually, since all people is totally different.
If you’ll be able to afford to splash out a lot on a sensible scale, Withings’ Body Scan may characterize a superb long-term funding in your well being. Just be ready to place within the work of turning as much as weigh in often. And be affected person as the corporate works out a few of its software program kinks.
