Forget Fitbit Sense: Amazon Halo is the hot new fitness tracker arriving this year

Fitbit has just announced a bevy of new devices, including the Fitbit Sense, Versa 3 and Fitbit Inspire 2. However, Amazon might have stolen Fitbit's thunder with a new arrival, Amazon Halo: a new fitness tracker band and accompanying app. 

But can it stand-up to comparison with the best fitness trackers currently on the market? Let's look at what we know...

Amazon Halo doesn't have a screen: instead, it's simply a recording device, relying on the app to show you its findings. The band records sleep and activity levels just like a standard fitness tracker, working with the American Heart Association to use holistic activity scores instead of a simple step count.

It also provides personalised recommendations to improve these activity and sleep scores. For example, the introductory video shows the app recommending you banish pets from the bedroom at night, or drinking less liquids before bed to reduce wake-up times.

However, the band also packs features we've not seen before. Rather than inputting your weight alone, the Amazon Halo app uses your smartphone's camera, asking you to take front, back and side-on pics to create a 3D model of yourself, which you can view on the app. 

It looks at Body Composition, calculating your body fat percentage using the 3D model, and claims the feature to be twice as accurate as leading smart scales. The pictures you use for your body scans are deleted by Amazon as soon as they're used to create the image, so your privacy is assured. 

You can also only scan yourself every two weeks, to stop negative behavioural patterns from developing, and this feature is only available for over-18s. Worryingly, the body scan is also said to come with a function allowing you to show the image with more or less body fat, which could lead to some unhealthy behaviours. 

Another new feature is Tone Analysis. With the Tone feature enabled, the Halo band uses its in-built microphone to listen to your speech all day. it analyses your tone of voice, noting if you sound happy, bored, or apologetic. 

Amazon states it wants to ensure 'social wellbeing' by helping what we say match what we're intending to convey. It also deletes every snippet of voice after analysis, and beams them from your band to the phone via Bluetooth, without going through Amazon's servers. It feels a little dystopian, but you're able to turn the band's microphones off at any time should you not wish to participate. 

Amazon's move into the fitness tracking arena is hardly surprising, and neither is the depth and scale of some of these metrics. We're expecting top-notch health, activity and sleep tracking from the new Amazon Halo – even if some of the new features like Tone sound a bit on the creepy side. 

The Amazon Halo band will be available with a free six-month subscription to the Amazon Halo service, priced at $99.99. It is currently available via Amazon's early access program for a reduced price tag of $64.99.
