[This review was collected as part of a promotion.] Heart disease runs in my family, and even though I try to stay active, I’ve never really known how well my heart is actually doing. Not just on the outside, but internally—like how fit it really is. This ring has been surprisingly helpful. The Cardio Age feature kind of freaked me out at first, but it was also a wake-up call. Seeing that number was a good push to take things more seriously—and what's cool is that I could actually see it improve a bit after a couple of weeks of better sleep and more consistent workouts. The VO2 Max reading is another feature I didn’t expect to care about, but now I check it way more often than I probably should. It’s satisfying to see it climb, even slowly. And cardio adaptability is probably what I’ve appreciated the most. It tells me how well my body is bouncing back from stress or workouts—and for someone with my family history, that feels like gold. As for the design, honestly, I’m not a huge fan of chunky wearables, so I was relieved that the ring looks clean and minimal. It doesn’t scream “fitness tracker,” which I love. Super light, too—I forget I’m wearing it most of the time. Heart disease runs in my family, and even though I try to stay active, I’ve never really known how well my heart is actually doing.

Especially if, like me, you're trying to stay a step ahead of genetics.

[This review was collected as part of a promotion.] I have had this ring for about 2 months now and love it. I am not usually super into this stuff, but the insights are unreal. I mostly wanted it to count my steps and help me with my sleep, but it does so much more like my stress levels, caffiene, and insights on my cycle. I also thought it would be uncomfortable but I barely notice it, and the only ring I wear is my wedding rings.

[This review was collected as part of a promotion.] I have been using the ring for about a year now and I am very satisfied. I track my sleep cycles every day, I follow the caffeine window, I use it a lot when exercising. All the results are very clearly interpreted, I use several powerplugs. I would definitely buy it again.

[This review was collected as part of a promotion.] I've been really satisfied with the Ultrahuman AIR. It's made a noticeable difference in both my sleep and morning routines. One of the biggest improvements I've seen is how much quicker I fall asleep—something I used to struggle with. The insights provided by the device have been genuinely helpful in understanding and optimizing my habits. I'm also really excited about the new tag system and what it will bring. It looks promising and could add even more depth to the insights and tracking. If I had to point out a downside, it would be that the step count seems to be underestimated compared to other devices I've used. It's a minor issue, but worth noting. Overall, it's been a great addition to my wellness toolkit.

[This review was collected as part of a promotion.] Been a month and a half since I’m using it. This has definitely been transformational for me because a lot of the patterns that my body portrayed are now finding logic because of the ring. I have changed my sleeping habits, eating time, etc. The only issue I feel right now is charging. I’m never able to charge it to 100% because the only time I take off the ring is in the morning for about 40-50 minutes before I’m ready to leave for work. Other than that it is GREAT!

[This review was collected as part of a promotion.] I've worn my ring religiously for two months, and I've been incredibly impressed in both the metrics, the customer service, and the app. The app is constantly evolving, which I love. At first, I found reading the data confusing, but as the app evolves, it is taking on a more "normal human" way of explaining things. I wouldn't mind the ability to choose between "normal human" and "intelligent data" with YouTube videos explaining--for example--what an HRV is and how it applies to your health and wellness. But I digress. Looks -- I wear gold exclusively. Dainty 14K gold jewelry at that. Not one person has clocked that this is a "smart ring." Comfort -- I wear mine on my right hand, index finger. It is more comfortable (and better protected) on my middle finger, but sometimes my sleep isn't tracked. The size must be just barely different from one finger to the next. (I also loved it on my ring finger, but my husband and BFF both preferred the index.) Durability -- For two months of nonstop wear, the ring has a few scratches. Mostly from holding a fork. (This is probably why they recommend wearing the ring on your NON-dominant hand. Why don't I listen?) Steps -- I wanted a kick to add more movement to my life. I enjoy that this tracks steps without my having to wear a bulky "fitness watch." However, if you are a desk-job girlie with a standing desk and a walking pad, this won't track anything. Something to keep in mind. I get around this by wearing a very old Apple Watch on my ankle. (A girl's gotta do what a girl's gotta do.) Cycle -- I skip multiple periods with medication. I have 3-4 a year. My ring seems to be keeping up with my cycles, regardless which is very interesting! Though it did have a bit of a tantrum when it was expecting my period and it didn't come for another week. Again, I've only had the ring for two months. I don't blame it for being confused. I'M confused. Hopefully, together, we can figure it out. I've learned so much about the different phases of a woman's cycle, though! The fact that it can warn me about upcoming mood swings or a possible decrease in immunity is AMAZING! I'm learning so much! Caffeine -- The caffeine window is so fun and improving every day! Now I can track WHAT I drink (which automatically calculates how much caffeine in mg) and WHEN I drink it. Love, love, love. Tags -- OMG THE TAGS. If you've had sex, protected or unprotected, if you have alcohol, what kind, if you're sleeping somewhere new, and so on and so on. I'd love more emotional options, but they still have options! And you can always create your own. However, I try not to create my own because there isn't a way to categorize the type of tag (for example: Emotional/Intimacy/Environment). Basically, you get OUT of the ring what you put INTO it. I'm having a great time.

[This review was collected as part of a promotion.] I bought this three months ago to track my steps and very happy so far. Step tracker is great and better than buying a watch. I find the battery is good and very easy to charge, lasts long and don't take to long to get to full charge. The sleep tracker is interesting with lots of information. There is a lot of information and I do find I skip over as some of it as I don't really understand it. The add ons are a nice touch and very interested what we will see in the future. As I said great step tracker, interesting for sleep, good for stress and like all add-ons

[This review was collected as part of a promotion.] I have been using the Ultrahuman Ring for a few months and I’m very happy with it. I especially like the sleep and stress insights, which help me understand my habits better. The app is intuitive but the only thing I feel is missing is a bit more guidance on how to interpret the data and clear tips on how to improve. Still, I highly recommend it!

Being able to see what habits garner positive results has helped me be consistent with the healthier changes I have made to my lifestyle. This product has seamlessly fit its way into my health journey.
