Amazon has entered the well being and fitness world with Halo, a subscription service and accompanying fitness band that unlocks an array of well being metrics, together with exercise, sleep, body fat and tone of voice evaluation, to find out the way you sound to others. Amazon’s entry into the fitness area is odd certainly, and bold. And we’re simply getting our minds wrapped round it. 

The band itself seems loads like a screenless Fitbit tracker, however with a number of totally different components: It has temperature sensing, much like Fitbit’s newest smartwatch, the Fitbit Sense, and a microphone that regularly scans a wearer’s voice to find out emotional tone. Yes, it is loads to absorb. And the service is instantly accessible for early entry. We have not even had an opportunity to attempt it out but. 

The membership half will begin at $65 for the primary six months ($100 as soon as the early entry deal is over) after which $3.99 a month after that. (International costs aren’t presently accessible, however $65 converts to about £50 or AU$90.)

Amazon’s Halo takes fitness monitoring to new and uncomfortable…


Loss weight Body fat evaluation with a smartphone camera 

Amazon thinks the idea of weight loss is flawed, and that body fat is a a lot better predictor of well being.

Most of us have been conditioned to obsess over our weight. The total food regimen business was constructed on it with applications, apps and gadgets that revolve round methods to lose kilos. 

But weight can fluctuate each day primarily based on components together with humidity, treatment, menstrual cycle and sickness. Plus muscle is extra dense than fat, and a scale cannot inform the distinction between the 2. You might actually work your ass off constructing muscle and burning fat, and never see the numbers on the size go down.

Rather than counting on weight, Halo focuses on body fat share, which is much less risky and takes much more time and work to alter. 

The gold commonplace within the medical world for body composition evaluation is a DEXA scan (twin-power absorptiometry), which might price as much as $100 at a lab. The Halo app does all of it utilizing your smartphone camera. Once you are taking your images, the app robotically eliminates the whole lot else within the background, calculates body fat p.c primarily based on body indicators, after which creates a 3D mannequin of your body, which is each cool and terrifying. The app requires you to put on minimal kind-becoming clothes and belief Amazon to take an image of you carrying it. The total course of takes seconds. 

Amazon’s Halo app makes a 3D render of your body to investigate body fat, whereas the fitness band retains tabs on sleep and exercise. 


If you feel uncomfortable, that is not shocking: The concept of body-scanning with a camera is already an ungainly proposition. Amazon doing this on a well being platform makes it really feel extra so. The pattern body-scan photographs Amazon confirmed me look very private — not essentially one thing I’d ever need anybody else to see.

That’s why Amazon guarantees that the completed body scans keep on your phone and will not be shared with anyone, together with the corporate, until you choose into that. According to Amazon, “the images are processed in the cloud, but encrypted in transit and processed within seconds, after which they’re automatically deleted from Amazon’s systems and databases. All scan images are fully deleted within 12 hours. The scan images aren’t viewed by anyone at Amazon and aren’t used for machine learning optimizations.”

Loss weight Watch that tone! 

Halo additionally presents a Tone evaluation, which has nothing to do with body tone, however relatively analyzes the nuances of your voice to color an image of the way you sound to others. It can let you understand if you’ve sounded out of line, weirdly sufficient. 

The fitness band has two constructed-in mics to seize audio and it listens for emotional cues. The firm says it is not supposed to investigate the content material of your dialog, simply the tone of your supply. It takes periodic samples of your speech all through the day when you choose in to the function. You allow the microphones by tapping the facet button and you will know when the mic is off when a purple LED lights up on the band. 


The voice scanning pulls out the wearer’s particular voice in conversations and delivers evaluation with associated emotional-tone phrases (like “happy,” or “concerned” within the Halo app). The concept, in accordance with Amazon, is to assist information you to ship higher tones of voice and talking types, like a vocal type of good posture. It is not supposed as a type of psychological evaluation, nevertheless it appears awfully laborious to attract the road on an idea like this. 

Amazon’s been exploring the thought of emotional tone-sensing since at least 2018, however that is the primary time it is approached the thought in any gadget. And in accordance with Amazon, the Tone function is just accessible on the Halo band for now. It can be restricted to the band’s microphone, however Amazon sounds open to exploring the thought on different gadgets, relying on how the early entry response goes from first-wave wearers. It’s a really odd factor to placed on a fitness band, and we do not know what that is like to make use of but.

Amazon guarantees that Tone voice samples are encrypted and saved solely on a wearer’s phone (shared from the band by way of Bluetooth with the encrypted key), are deleted after evaluation and will not be shared to the cloud or used to construct machine-studying fashions.

Loss weight Sleep evaluation with temperature monitoring

The sleep evaluation features a body temperature to detect variations which will influence sleep. 


The app supplies a complete sleep evaluation with a breakdown of the totally different phases of sleep and total sleep rating, very similar to different fitness trackers. It additionally goes past the fundamentals by maintaining observe of your total body temperature throughout sleep and making a baseline for every individual. It then charts your common temperature every night time relative to your baseline that can assist you establish variations that might have an effect on your well being and the standard of your sleep. 

The Halo band will not present a particular body temperature, just like the way in which different temperature wearable gadgets just like the Oura Ring already work.

Temperature has grow to be a trending wearable metric within the COVID-19 period: The Oura Ring has one and Fitbit’s newest Sense watch has one too. Amazon’s Halo crew is pursuing analysis for COVID-19 symptom detection on its wearables, very similar to different well being wearable firms, however no particular research or plans have been laid out but.

Loss weight Activity monitoring: A week at a look 

The exercise app is predicated on a weekly level system. 


Halo additionally does primary fitness monitoring primarily based on the data from the band. It can robotically observe walks and runs, however you will have to enter the app and tag every other exercises manually. 

It rewards you for any kind of motion or exercise, however provides extra factors for extra intense exercises and subtracts factors for sedentary time. And it does not preserve a each day tally of your exercise, your rating is predicated on the factors you accrued throughout the whole week. The total image of train, sedentary time and lively time is mixed into one tally.

Amazon’s sleep and exercise scores and different AI instruments would require an Amazon Halo subscription; in any other case, the band will default to extra primary monitoring information. Much like Fitbit and its Premium service, this seems to be persevering with a pattern of fitness gadgets that anticipate a subscription mannequin as a part of the package deal.

Loss weight A lot of labs and companions, however no Google or Apple integration

A Labs part of Amazon Halo seems just like what’s on Fitbit’s Premium service, with numerous multiweek well being and fitness objectives to choose into, and companions lined up from OrangeTheory to Weight Watchers. Amazon guarantees these challenges are scientifically vetted, nevertheless it additionally appears like these challenges will preserve being added to over time. 

But at the least at launch, Halo is not going to tie in to Apple’s HealthEquipment or Google’s Fit App which places it at a drawback with people who find themselves already deeply invested in both for well being monitoring. Amazon is leaning on Weight Watchers, John Hancock Vitality wellness program, and some others that can be capable to hook into Amazon Halo well being information.

Loss weight The looming privateness query

There’s numerous course of by way of options, and whereas some appear attention-grabbing and revolutionary, the most important barrier to entry is privateness. Sharing any type of well being information (not to mention unflattering seminudes) requires subsequent-degree belief, and also you may not be ready to offer Amazon that belief. The firm does not precisely have essentially the most pristine observe report in the case of maintaining person information personal. Alexa-enabled gadgets have been within the sizzling seat for storing private conversations “for machine learning purposes.” And Amazon’s Ring doorbell has had a sequence of privateness mud-ups. 

Halo places privateness in your palms by permitting you to choose out of information sharing with Amazon and third-occasion apps in addition to disable the microphone on the band, nevertheless it’s nonetheless going to be an uphill battle. That is until its options show to be earth-shattering and well worth the privateness threat, which stays to be seen.

Loss weight Amazon is late on arrival

The lack of connection to Apple or Google is telling. Amazon’s making a play within the well being and fitness information area, and with Google, Fitbit and Apple already deep in, it is a huge query as to how Amazon will make waves. Or, the place Amazon Halo will go subsequent. It’s a platform as a lot as a wearable, and it appears like Halo’s early-entry experiment may be the tip of the iceberg.
