[This review was collected as part of a promotion.] I have had the ring for a few months now. To be honest it came defective and I had a hard time having it replaced.. it took almost two months to have it replaced. That being said it seems to work well. There is a lot of information tracked so it is difficult to know how accurate it really is. The sleep tracking and temperature tracking work well.

[This review was collected as part of a promotion.] I bought this ring a few months ago and I have loved it! I was nervous with all the negative ratings talking about the battery but I have had no issues and when I keep my ring in “Chill Mode” it lasts about 5 days. It is very accurate in detecting sleep and they are always updating the ring and adding new features! I wish I could connect it to my Strava app but that is my only complaint.

[This review was collected as part of a promotion.] I bought this 3 months ago, I was really happy with the device and the software, and happy to see you're pushing updates very often with new feature. But the ring doesn't work anymore since a week ago. The battery runs out after a few hours, even after charging it completely. Something has somehow... changed, and it doesn't work as it should anymore. I've updated the firmware, and run diagnostics, but nothing fix the issue. Which im quite disappointed now, I can not use it and I have no data about myself since the issue started. I have a ultramarathon this weekend and won't be able to use it.

[This review was collected as part of a promotion.] Love how it tracks my sleep & recovery so well Helps me know if I need more rest as a new mom I use it for yoga & indoor walks—super accurate Got the silver ring—so pretty & goes with outfits Perfect balance of health tech & wearable style

[This review was collected as part of a promotion.] I love the data the ring provides! It has been really interesting seeing what affects my sleep and hoe I can make improvements to help shape how I feel throughout the day. My only negative is how long it takes to charge. I want to wear it at all times to get the data. It would be nice if it could be fully charged in 30 mins so I don’t have to have it off for so long. Overall an amazing product!

[This review was collected as part of a promotion.] I am very happy with the app, the comfortably and easy usage of the ring. Also I like the ongoing improvements and additions. The only improvement I have is that once my ring was broken, it took quite a while to get an replacement because I had to do several firmware updates before it was agreed to get a replacement. The support was always super quick and helpful but this I found a bit dissapointing.

[This review was collected as part of a promotion.] Bought this 3 months ago and it was a different experience compared to smart watch. you can still monitor your health and wear your favorite watch (not smart watch). Sleep tracking is also accurate and giving helpful insights. Sleep score was awesome and it pushed me to reach my goal. Sun exposure was also helpful and it gave me a reason to go out during the day.

[This review was collected as part of a promotion.] Really deep sleep insights that have helped me change my sleep habits and hygiene. I can also really see how external factors affect my sleep and numbers like my resting heart rate and start to better manage lifestyle overall.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for a few months now, and I can confidently say it’s one of the best investments I’ve made for my health and wellness. What sets it apart is the accuracy and depth of insights. It doesn’t just count steps or measure sleep—it dives into HRV, body temperature, recovery, metabolic score, movement index, and more. The Ultrahuman app ties everything together beautifully, giving clear and actionable feedback rather than just raw data. Sleep tracking is incredibly detailed, helping me understand my sleep cycles and how well I’m truly recovering. I also love how it detects subtle physiological changes that indicate stress or strain—especially useful if you’re active or training regularly. Design-wise, it’s sleek, minimalist, and surprisingly comfortable—I forget I’m even wearing it. Battery life is solid too—I get around 5–6 days on a single charge. Most importantly, it’s not just a tracker—it feels like a wellness coach on your finger, encouraging better habits without being overwhelming. If you’re looking for a smart ring that goes beyond the basics and truly supports performance, recovery, and metabolic health, the Ultrahuman Ring is absolutely worth it.

[This review was collected as part of a promotion.] This has been a great product so far. I bought this to run alongside my Garmin Tactics Pro. It’s very interesting to see the difference in monitoring between the two. The amount of data that the ring gathers is amazing and I am excited to see new features coming in the future. As someone who is not use to wearing rings, it was an adjustment getting use to having it on my index finger. Like anything you get use to it after a while. Highly recommend for anyone looking for tons of insight. I’ve not had anything else that gives this much of a deep dive into vitals and it’s been a blast getting to learn through it all.
