The Halo tracker is unique in its design. It doesn’t have a display or a vibration motor. This makes the Halo a great choice for people who want their wrist to be clear of distractions.
It offers a variety of sessions and workouts to improve your health. It also has a variety of meditation, mindfulness, and tone-focused content.
Tone of Voice analysis is the best feature. This analyzes your voice during interviews and other public speeches to improve vocal quality. You can also take a voice selfie to improve your voice clarity and overall tone.
This is a very useful feature, especially when it's difficult to find the right voice for interviews. You can also review your recordings to hear how you sound, and make any necessary improvements.
Sleep monitoring is another key part of the Halo's data-centric approach to fitness tracking, as it tracks your sleep from start to finish and provides scores based on each sleep cycle. It can also measure your body temperature, which is helpful when determining how restful your night's sleep was.
Amazon has committed that the Halo will be kept private, and users can opt in to use its voice tone analysis and body scan features. The company explains that it processes the body-scan photos in the cloud and automatically deletes them when they're no longer used. This does raise privacy concerns.
The paired app allows you to body-scan by taking a photo of yourself wearing skivvies. It is only available to people over 18. Multiple photos are required to accurately determine your body fat percentage.
This adds complexity to your fitness tracker, since it isn't comparable to traditional metrics like calories burned or steps. It does, however, provide a better overall picture about your activity and your health over time.
The voice tonal analysis, for instance, uses two microphones to listen and analyze your speech. This is a useful feature that anyone can use to project a positive image at work or with their friends.
You should note that this feature is not available without a paid subscription. To continue using the feature, you will need to pay $4/around PlayStation3 / AU$5 per month after six months.
The Body Composition feature is also a notable feature. This uses height and body data, as well as photos taken from your body, in order to calculate your overall body composition. It's a far more sophisticated way of measuring body fat than Withings' bioimpedance-based technology, but it does require you to provide photos and may raise some privacy concerns.
As far as fitness tracking goes, the Halo doesn't offer much that the Apple Watch or Fitbit don't. Although it will provide a visual overview of your progress and help you determine if you have met your weekly goals, the Halo lacks the bright graphics found on Fitbit or Apple Watch. Access to the most advanced features such as body scanning and voice tone analysis will require a subscription.
