Ultrahuman

Smart ring developer, Ultrahuman, has announced plans to open a manufacturing facility within the US to help accelerate its production capacity. This is the first time a smart ring will be completely manufactured within the US. Ultrahuman says the new factory will be located in Indiana with plans on opening within the next six months.

The Ultrahuman Ring AIR is the thinnest and lightest high-tech wearable available. Similar to the Oura Ring, Ultrahuman tracks your sleep, activity levels, and recovery. Of course, there are a few differences, which you can learn about in our video review below. Perhaps most compelling of all, the Ultrahuman Ring AIR does not require an ongoing monthly subscription.

You buy it. You own it. No additional payments are required.
