As a veteran smartwatch and fitness tracker reviewer, it's rare that I get to approach a product with a completely fresh set of eyes, but that's what happened with the Ultrahuman Ring Air. This was the first smart ring I had ever tested, and in some ways, that made me the perfect person to review it. I approached it not as a seasoned biohacker, but as someone experiencing it the way most buyers would: curious, a little skeptical, and wondering whether it could replace my smartwatch. Better yet, would it actually improve my habits?
Turns out, it did. Not because the data was perfectly accurate (more on that later), but because after over a month of wearing the Ultrahuman Ring Air, the simple act of logging consistently made me more aware of how my daily routine, especially sleep, impacts my body. It didn't replace my smartwatch, but it complemented it in a way I didn't expect.
