Review: Amazon Halo is incredibly invasive, but helps you learn about yourself

| |

Amazon definitely raised eyebrows when it introduced its Halo health tracker. This tracker does what most others are able to, similar to exercise and sleep monitoring — nevertheless it additionally goes nicely previous that, and crosses nicely into uncomfortable territory.

There isn’t any getting round it, the Amazon Halo tracker is invasive. However for those who get previous that, chances are you’ll be taught a bit extra about your self that no different health can inform you. Earlier than stepping into the extremely private tone evaluation and photo-based physique composition, let’s take a look at the tracker itself and the way it performs as a regular health tracker.

Amazon Halo health tracker – Design and luxury

The Amazon Halo band comes with black + onyx (what we picked up), winter + silver, and blush + rose gold. There are different bands out there, together with a sport band that’s fabricated from silicone moderately than material.

We discovered the default material band comfy sufficient because it sat on our wrist, about two finger widths behind our wrist bone. For one thing you put on all day, it must be comfy.

From the skin, you primarily see the material band, however under it, simply atop your wrist, is the physique of the Halo. This small tracker suits in opposition to your wrist, the place it might measure your coronary heart price with an optical tracker and your physique temperature when you sleep.

As soon as you have arrange the band within the Halo app, you’re delivered to an summary of your tracked metrics with exercise and sleep proper on the prime. Every of the tiles offers you an summary of the metrics it is captured as a snapshot, however tapping into them supplies rather more perception.


Halo tracks your exercise with opaque “factors.” These factors are imagined to extra precisely signify your health for the day moderately than pure energy burnt or steps taken. We would say it’s akin to Nike’s gasoline metric. It makes understanding tougher as, out of the field, you do not essentially have a scale for comparability such as you would with steps or energy, however after a while, you will have a greater concept of what a great level worth is. The app additionally tries to assist with varied shade coding.

Fitness tracking

Health monitoring

Viewing your exercise, you’ll be able to view by week, day, or month to see how you’re progressing over time. It then breaks down your factors for every day by what number of you earned in numerous classes. Intense classes — like a strenuous exercise — earn essentially the most factors. Reasonable — similar to taking steps two at a time — made up the majority of our factors once we weren’t hitting the elliptical. Sedentary time will subtract factors out of your every day complete, encouraging you to remain transferring.


Exterior of health monitoring, sleep monitoring is the second-most exercise tracked. Apple Watch has had third-party sleep monitoring for years however gained native help with watchOS 7. In comparison with Apple Watch, Halo tracks rather more data.

The app reveals a graphical illustration of your night time’s relaxation from the time you bought into mattress to while you fell asleep, in addition to disturbances through the night time and every of your sleep cycles. Halo will rating your night time’s sleep combining all of that information into one quantity. This makes it straightforward to know how restful your night time was and the way refreshed you must really feel through the day.

Halo can measure your night time’s physique temperature and the way a lot it modified. This, too, aids in understanding how nicely you slept.

That every one stated, there was debate as to how correct sleep monitoring is at figuring out REM, mild, or deep sleep cycles. That may very well be why Apple solely affords high-level monitoring as an alternative of displaying extra in-depth information that will not be as correct as many assume.

Amazon Halo health tracker – It is time to get far too private

Sleep and health monitoring is the place Halo’s run-of-the-mill performance stops and the rather more private options start.

It is all the way you say it

Have you ever ever puzzled the way you come off to others? Are you dismissive? Cheerful? It may be exhausting to be conscious of how others interpret your tone, and Halo hopes to shed some mild on this.

To take action, it’s essential to first allow the tone monitoring within the app, acknowledging that the microphone will at all times be on and listening. Amazon does put its privateness coverage front-and-center, however it’s nonetheless a bit unnerving to allow.

Halo have to be skilled to acknowledge your voice in order that different voices do not get analyzed as an alternative. Halo does this by asking you to learn aloud in a quiet house a number of passages from well-known books— suppose Dickens or Caroll. It is sort of a pleasant throwback to Amazon’s roots as a bookseller.

Tone metrics

As soon as your voice is enrolled, you are all set. Now, anytime that you simply converse, Halo can be listening and analyzing what you say. That is recorded within the app and damaged down between pleasure with excessive vitality, proud of decrease vitality, low vitality with much less positivity, and displeased or irritated. The remainder of your tone is positioned into the impartial bucket.

You possibly can see how a lot of your time talking suits into these classes. Halo additionally denotes notable moments or conversations. It highlights instances you have been completely happy, discouraged, skeptical, and extra. It tells you that you simply had a sure variety of phrases that it recognized. For instance, this morning, Halo flagged us as skeptical for just a few seconds. One other phrase we stated got here off as skeptical and confused sounding.

The app does not inform you what phrases you stated however moderately offers you instances as an alternative and leaves you to determine what dialog you have been having on the time.

Contained in the app is a “reside” tab that tracks your coronary heart price and offers you real-time voice evaluation. As you converse, it reacts near-instantly and describes the tone of what you are saying.

Real-time tone analysis

Actual-time tone evaluation

Between the real-time evaluation and every day summaries, we surprisingly discovered this evaluation very correct. As we modified what we have been saying, the indicator moved throughout the chart and precisely described our tone. Within the video above, you’ll be able to see the evaluation for your self as we spoke.

A tradeoff with tone monitoring is battery life. Reasonably than seven days of battery life with tone off, turning tone on will drop your battery to simply round two days.

Maybe the larger tradeoff, although, is strapping an Amazon microphone in your wrist across the clock.

Present us what you bought, all of it

If listening to your voice 24/7 wasn’t invasive sufficient, Halo additionally affords physique composition. Totally different units can measure this in numerous methods. Some units like a Withings scale can measure your physique composition utilizing bioimpedance. Others calculate it based mostly solely on the load and peak numbers you feed it. Halo does so by combining the numbers you present with precise images.

Halo asks you to make use of your iPhone to snap pics of your self with “minimal clothes” — e.g., as shut to simply underwear as you’re comfy. For that motive, Amazon limits this function to those that are no less than 18 years previous. Not solely is Amazon asking you to take images of your self in your underwear, however it’s importing these images to the cloud as nicely. These photographs are processed within the cloud earlier than being deleted, however we won’t think about many individuals can be excited to do that.

In the event you select to ship Amazon your scantily-clad selfies, the app will generate a customized 3D avatar of you and break down your physique composition. You possibly can monitor your physique fats share over time to see the way you enhance.

In comparison with simply utilizing your peak and weight, the picture should definitely enhance the accuracy of your measurements, however there is no such thing as a getting across the invasiveness and creepy issue.

Is Amazon Halo definitely worth the tradeoff?

We’re very torn on the prospect of Halo. Taking a look at what you get out of it, it’s pretty tempting. The physique composition is extra correct than different wearables, and the tone evaluation is exclusive. We very a lot liked to see how we have been being perceived, and sleep monitoring and health monitoring are necessities. However on the similar time, it’s virtually as if we’re crossing an invisible line.

Halo is cool, but too scary

There’s a clear differentiation between Apple and its user-first privateness coverage and Amazon and its propensity to promote or monetize consumer information. After a six-month free trial, Amazon does cost $4 a month for Halo monitoring, which might be for the very best as a result of it means Amazon is much less more likely to do one thing along with your consumer information.

We have come to belief Apple Watch. All of your information is captured and saved regionally, encrypted to the nth diploma, and is constructed by a privacy-focused firm. Halo is completely new, comes from an organization with a questionable monitor file on privateness, and easily has not earned our belief.

Adopting Halo appears like we have given up on our privateness and handing over each side of our life to Amazon. The info you get from Halo is cool, however in our minds, what now we have to surrender is an excessive amount of.

  • Snug to put on
  • Distinctive talents to measure physique composition and tone
  • Privateness considerations are a tough tablet to swallow
  • Costly for those who do not use tone or physique composition options
  • Generic trying
  • Month-to-month price
