This is a little embarrassing to admit as someone who reviews wearables for a living, but the Ultrahuman Ring Air is my first-ever smart ring. I've tested just about every smartwatch and fitness tracker on the market, but never a ring. And honestly, that probably makes me the perfect person to review it -- not as a biohacking pro, but as someone who went into this exactly how most buyers would: curious, slightly skeptical and wondering whether it would make me ditch 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.
