Amazon is entering the wearable space with new Halo

Amazon is entering the wearables market in a big way. The company on Thursday introduced a wristband for health and fitness tracking called Halo, alongside a subscription service and smartphone app. The space is currently dominated by the Apple Watch and devices from Fitbit, which is awaiting regulatory approval for an acquisition by Alphabet’s Google. Amazon’s Halo product builds on these older fitness tracking devices with features that have never been seen in a mainstream wearable device, including one that tracks a user’s emotional state by listening to the tone of their voice, and another that provides a three-dimensional rendering of their body with an estimated body fat percentage.
