The Amazon Halo Band was a health-focused fitness tracker released by Amazon in 2020, designed to measure body composition, activity, sleep, and even the tone of your voice, all without a screen. For a deeper look at its ambitious but ultimately short-lived feature set, see our hands-on experience with Amazon's first AI-assisted fitness tracker. It has been discontinued, and as of August 1, 2023, all Halo devices and the companion app no longer function, making this article a complete record of what the device was, how it worked, and why it mattered.
What Is an Amazon Halo Band? The Health-Focused Tracker Explained
The Amazon Halo Band was a subscription-based wearable that prioritized wellness over notifications. Unlike most smartwatches and fitness bands, it deliberately lacked a screen, so there were no buzzing alerts, glowing displays, or app icons vying for your attention. Instead, the band worked silently in the background, collecting data through sensors and sending it to the Amazon Halo app on your smartphone, where AI-powered insights turned raw numbers into actionable health guidance. Its core promise was to help you understand your body better, not just how many steps you took, but how much body fat you carried, how well you slept, and even how you sounded to others in conversation.
The Discontinuation: Amazon Halo No Longer Exists
Amazon officially ended the entire Halo program on July 31, 2023. The very next day, August 1, 2023, all Halo devices, including the Halo Band, and the Amazon Halo app ceased to function entirely. This meant no more syncing, no more activity tracking, no more sleep analysis, and no access to any stored health data. The shutdown was abrupt and complete, leaving existing users with a non-functional piece of hardware. Amazon did offer refunds: if you purchased a Halo Band within the 12 months preceding April 26, 2023, you received a full refund for the device. Additionally, any unused prepaid subscription fees were also refunded to customers. Before the cutoff, Amazon advised users to download or delete their health data from the Settings page in the Halo app, because all remaining data was permanently deleted after August 1, 2023.
What Made the Halo Band Different: Key Features
The Halo Band stood out because it introduced two features no other wearable offered at the time. The first was Body composition analysis: using the smartphone camera, the Halo app scanned your midsection and employed computer vision technology to estimate your body fat percentage. Amazon claimed this method was more accurate than smart scales, which only measure bioelectrical impedance through your feet. The second unique feature was Tone of voice analysis. The band's built-in microphones listened to the sound of your voice throughout the day and analyzed qualities like energy, positivity, and dominance, giving you feedback on how you came across in conversations. You could mute the microphones anytime you wanted privacy. Beyond those signature tools, the Halo Band also tracked standard metrics: heart rate, sleep stages, activity levels, and steps, all presented in the Halo app with simple, jargon-free summaries.
Hardware and Subscription: How the Halo Band Worked
Physically, the Halo Band was a minimalist flexible band with no display. Instead of a screen, it had a small LED indicator light and a single button. Inside, it packed an accelerometer, a temperature sensor, a heart rate monitor, and two microphones. The band was water-resistant up to 50 meters, so you could wear it while swimming or doing other shallow-water activities, and its battery lasted up to seven days on a single charge. However, the hardware was only half the story. To unlock the advanced insights, body composition scans, tone analysis, sleep scoring, and personalized coaching, you needed a monthly subscription priced at $3.99 per month in the US. Without the subscription, the band essentially became a basic step counter, and with the discontinuation, even that functionality disappeared. The Halo Band was a bold experiment in screen-free health tracking, but its reliance on a subscription and Amazon's decision to kill the platform mean it now exists only in the pages of tech history.
