[This review was collected as part of a promotion.] I really like the ring, it comes with several reports and great insights on cardiovascular status and brain health. The fertility/ovulation tracker is interesting and why I got this product, but I wish it could be developed further and become a central part of the app instead of just a plugin. There's another plugin on caffeine consumption window, which is interesting but not necessarily accurate. For instance, I know I am a fast metabolizer, can drink coffee or energy drinks just before bed, but the ring is not capturing that. Otherwise I am looking forward to the updates!

[This review was collected as part of a promotion.] Overall, I'm very happy with my Ultrahuman Ring AIR. The tracking features are great, the battery life is good, and the app is very user-friendly. My only complaint relates to the fading of the ring over time. I have had my ring for just under 1 year and it has gone from gold to mostly silver due to fading.

[This review was collected as part of a promotion.] The Ultrahuman Ring Air has become an essential part of my daily routine. I especially appreciate how it gives me actionable insights into my health without having to wear an unsightly watch. I especially appreciate: Sleep tracking: The detailed breakdown of my sleep cycles helps me understand my rest patterns and make adjustments for better quality sleep. Cycle tracking: Being able to monitor my menstrual cycle alongside my overall readiness and recovery trends is incredibly helpful and makes the data more meaningful. Activity monitoring: I love seeing my steps automatically tracked—even on days when I’m not consciously thinking about movement, the ring keeps me on top of my activity goals. Caffeine consumption timing: One standout feature is seeing the ideal times to consume caffeine; it’s a simple but powerful detail that helps me avoid having late-day coffee that might impact my sleep quality. Overall, the Ultrahuman Ring Air provides a holistic and intuitive view of my health habits, making it easier for me to spot patterns, stay motivated, and make smarter choices each day.

[This review was collected as part of a promotion.] Ultrahuman Ring Air has been a lifesaver in tracking my sleep as I am not able to sleep with a watch on. The sleep, caffeine, and recovery insights are very useful in improving my quality of life each day. Also, the build quality and look is great!

[This review was collected as part of a promotion.] I purchased the ring in August last year and have enjoyed its features so far. However, I've noticed the battery has been draining very quickly recently, lasting less than a day, which is quite frustrating.

[This review was collected as part of a promotion.] I love the ultra human air. I feel like the in depth and multi faceted things it recognizes far surpasses other health rings out there. My only critic is when logging a workout sometimes it will stop tracking randomly and go back to the main page of the app basically not tracking your entire workout but this only happens maybe 1 out of every 10 times.

[This review was collected as part of a promotion.] I have been enjoying the ring as a tracking device. I have had to switch from smart watches due to skin rash, loving the lightness of it and no skin issues! One downside is the loading time, for example steps they're not reflecting live on the app. Another thing I wish for if it's less bulky, and has nicer finishes.

[This review was collected as part of a promotion.] The battery needs to be charged more often than expected unless I turn it down to only track the minimal (sleep etc). Maybe it being in the sauna drains the battery or when I used to click a functional workout real time maybe that is also draining the battery. Lastly, I have the silver, and there are lots of hairline scratches on it and it feels like plastic on top. Maybe there can be other cooler finishes like textured to help disguise the scratch potential? Otherwise cool and lots of info and options.

[This review was collected as part of a promotion.] I bought my ring in June and I’ve been primarily using it to track my sleep! I find it gives very accurate readings and is really good at giving me suggestions and graphing my data. The only reason I gave it four instead of five is that the ring scratches super easily. I have the gold and a lot of it is basically silver at this point. I don’t wear rings around it at all so it’s not rubbing on anything. The battery is okay, I charge it probably every 3 to 4 days. I was hopeful it was going to last longer. Also, often when I go into the app, it takes quite a while to load my data and I have to refresh it quite a few times.

[This review was collected as part of a promotion.] I’m happy with the statistics if she provides however I had a bunch of problems with the first one and I had to have it warranted. So far, the new one is working properly. I hope it lasts longer than the first one.
