Amazon has entered the health and fitness space with Halo, a subscription service and accompanying wristband that unlocks an array of health metrics, including activity, body fat, sleep, and tone of voice analysis, to determine how you sound to others. Customers in the U.S. can request early access to Amazon Halo with the Amazon Halo Band and 6 months of Halo membership available for a special price of $64.99.

“Despite the rise in digital health services and devices over the last decade, we have not seen a corresponding improvement in population health in the U.S. We are using Amazon’s deep expertise in artificial intelligence and machine learning to offer customers a new way to discover, adopt, and maintain personalized wellness habits,” said Dr. Maulik Majmudar, Principal Medical Officer, Amazon Halo. “Health is much more than just the number of steps you take in a day or how many hours you sleep. Amazon Halo combines the latest medical science, highly accurate data via the Halo Band sensors, and cutting-edge artificial intelligence to offer a more comprehensive approach to improving your health and wellness.”

Amazon Halo Band is purpose-built to focus on your health and wellness—unlike smartwatches and fitness trackers, it doesn’t have a screen or constant notifications. The small sensor capsule delivers highly accurate data, and includes an accelerometer, a temperature sensor, a heart rate monitor, two microphones, an LED indicator light, and a button to turn the microphones on or off, among other functions. Amazon Halo Band is water-resistant for all-day wear and the comfortable fit means it won’t snag or irritate at night. Plus, the battery lasts up to seven days and fully charges in under 90 minutes. Customers can choose from three fabric band colors at purchase, with fabric and silicone sport accessory bands available in 15 additional colors, reports BusinessWire.

The Amazon Halo app has a suite of five core features to understand health and wellness:

Activity

Informed by American Heart Association physical activity guidelines and the latest medical research, Amazon Halo awards points based on the intensity and duration of movement, not just the number of steps taken. Amazon Halo deducts one activity point for every hour over eight hours of sedentary time in a day, outside of sleep. A baseline goal of 150 activity points is set and measured weekly.

Sleep

Amazon Halo uses motion, heart rate, and temperature to measure time asleep and time awake; time spent in the various phases of sleep including deep, light, and REM; and skin temperature while sleeping. In the morning, Amazon Halo delivers a sleep score out of 100, any deviation from baseline sleep temperature, and a hypnogram showing time spent in each sleep phase.

Body

Using new innovations in computer vision and machine learning, Amazon Halo lets customers measure their body fat percentage from the comfort and privacy of their own home, making this important information easily accessible. The Amazon Halo body fat measurement is as accurate as methods a doctor would use—and nearly twice as accurate as leading at-home smart scales, Amazon says.

Tone

The innovative Tone feature uses machine learning to analyze energy and positivity in a customer’s voice so they can better understand how they may sound to others, helping improve their communication and relationships. For example, Tone results may reveal that a difficult work call leads to less positivity in communication with a customer’s family, an indication of the impact of stress on emotional well-being.

Labs

Amazon Halo Labs are science-backed challenges, experiments, and workouts that allow customers to discover what works best for them specifically, so they can build healthier habits. Customers can choose from labs created by Amazon Halo experts, as well as brands and personalities they already know, including 8fit, Aaptiv, American Heart Association, Exhale On-Demand, Harvard Health Publishing, Headspace, Julian Treasure, Lifesum, Mayo Clinic, Openfit, Orangetheory Fitness, P.volve, Russell Wilson, Relax Melodies, SWEAT, and WW.
