Enjoyed the features while ring was functioning
on July 29, 2025
Posted by: Lenora
My experience has been great so far, I have loved all the features the ring has to offer. However, recently the ring has not stayed connected and will not collect sleep data because of this. I did purchase the warranty, so I am hoping this process is smooth and the issue can be resolved quickly. I’ve really enjoyed my ring so far, so I am eager to have it replaced or back to working condition.

Easy to Understand
on July 29, 2025

[This review was collected as part of a promotion.] This ring has truly helped me understand my health to the fullest. I originally purchased to track my sleep, and it has helped me get my health on track by understanding my heart rate, HRV, and stress. I've already set personal records by exercising more and lowering my stress levels and heart rate! The only reason why I took off one star is because the smart alarm in the app is a bit buggy. There have been multiple times the alarm didn't go off even though it was set for the correct date/time.

[This review was collected as part of a promotion.] I have loved every minute of having my ultra human ring! I purchased mainly to track my fertility specifically my temperature, but it has been so beneficial in other areas as well. Love love this device!

Exceeded expectations

[This review was collected as part of a promotion.] The ring has helped me triply track how much I’m moving (or not!). It’s also really fun to look at the insight for my sleep and be able tot reflect how certain habits impact my sleep more than I thought. I’m pleasantly surprised at how accurate the ring is at tracking my time of the month, especially as it’s all over the place.

Buy it!

[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.

Game-Changing Insight for Recovery and Readiness

[This review was collected as part of a promotion.] I’ve been testing the Ultrahuman Ring Air, and it’s quickly becoming a valuable tool for monitoring recovery, sleep, and overall readiness. The design is sleek and comfortable, making it easy to wear around the clock without disrupting daily activity or training sessions.
What stands out most is the depth of insight provided. HRV tracking, sleep stage analysis, and metabolic health markers are presented in a way that’s both actionable and easy to interpret. The seamless integration with Ultrahuman’s ecosystem adds another layer, allowing for a more holistic approach to athlete monitoring and personal performance optimization.
For anyone serious about understanding their body’s response to stress, recovery, and training load, the Ultrahuman Ring Air offers a level of precision and usability that’s hard to match. I’m excited to continue exploring how this can support athletes at the elite level.
