Amazon Halo – Measure activity, sleep, body composition, and tone of voice

Whatever your goal, schedule, or style, Halo always has a new way to help you work out, sleep better, reduce stress, eat healthier, and more.
Frequently asked questions
How does Halo protect my privacy?
Privacy is foundational to how we designed and built Halo. There are multiple layers of protections in place to keep data safe and in your control. We’ll never sell health data that ties directly to you. You can download or delete your health data directly from the Halo app at any time.

Does Body Composition work for all bodies?
Body Composition supports those aged 18+. However, it has reduced accuracy for customers over 500 pounds or 50% body fat, pregnant women, those who use wheelchairs, and people with certain physical differences like missing or prosthetic limbs. We are continually working to support more body types.
Do I need a Halo Band to use Halo membership?
Yes, currently a Halo Band is required to access Halo membership.
Does Tone work for all voices?
Tone currently works best for American English speakers, but Halo is always getting smarter.
How do Tone and Body Composition ensure my privacy?
If you choose to enable Tone, a voice profile is required and helps Halo analyze only your voice. You can turn off the mics at any time with the mute button on the band. And your speech samples are deleted automatically after being processed so no one ever hears them. Your Body Composition images are processed in the cloud then automatically deleted so no one but you ever sees them.
What if I decide not to renew my membership?
If you choose not to continue your membership, you’ll retain access to basic sleep time, heart rate, and step tracking.
