Following the invitation-based release earlier this year, Amazon’s Hollow Band Activity Tracker is now available for purchase by anyone in the United States. The wearable can be purchased for $ 100 on Amazon and Best Buy. It is available in three colors: Black, Blush and Silver. You have to pay to get it from the company’s Hollow subscription fitness program. An Appreciation Monthly Member will refund you $ 4 after the expiration of the six-month trial period.
The Hollow Band does not have a display like your traditional Fitbit Tracker or Apple Watch. That is, there are no other abilities that can be worn so far. It includes two built-in microphones that measure the tone of your voice. Every day, it will give you suggestions on how to sound a tonal break and heat. The accompanying Hollow app also includes a feature that allows you to take a full body selfie, which Amazon uses to estimate your body fat percentage.
