[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for a few weeks now, and I can honestly say it has completely transformed the way I approach my health, fitness, and recovery. As a busy mom of two who’s always on the go, I needed something that could help me stay accountable, track my wellness, and still fit seamlessly into my life — and this ring does exactly that. First of all, the design is sleek and minimal, so it looks great whether I’m working out, at work, or going out. It’s comfortable to wear 24/7 and doesn’t feel bulky or intrusive at all. What really blew me away, though, is the accuracy and depth of insights. The sleep tracking is incredibly detailed, helping me understand how rest affects my mood, energy, and workouts. The recovery score helps me avoid overtraining, and I love how it even gives nutrition and movement suggestions based on my data — all in real time. The app is user-friendly, beautifully designed, and gives actionable insights without feeling overwhelming. It doesn’t just track numbers — it helps me actually improve every day. Whether you’re a fitness enthusiast, a working professional, or just trying to live healthier, I genuinely think the Ultrahuman Ring is one of the best investments you can make for your body and mind. I feel more in tune with myself than ever before — and I’m never going back

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring for a couple of months now, and I genuinely think it's a brilliant alternative to smartwatches—especially if you're someone like me who prefers classic watches over digital ones. This little device has significantly improved my quality of life, drawing my attention to things I had never really considered before, like sleep quality and my personal favorite feature: the “caffeine window.” It’s surprising how much insight such a small ring can offer. I never thought it would have such an impact—not just on my awareness, but also on my daily habits. To be honest, I didn’t expect it, but the ring has even helped me lose weight in just 2–3 months. One small piece of advice: if you're considering buying one and plan to lose weight, get a size that's almost too small. I went with a comfortable fit at first, but after shedding some weight, the ring became a bit loose and now sometimes rotates on my finger, making it harder for the sensor to collect data consistently. Highly recommended—this is probably one of the smartest investments I’ve made in my health.

[This review was collected as part of a promotion.] Love my ultrahuman ring! I’ve had it for a few months and wear it everyday! Only thing is I wish it would be better at taking treadmill steps in to account for overall steps! But otherwise I love being able to track my sleep and movement. The app makes it really easy to navigate

[This review was collected as part of a promotion.] I’ve had the Ultrahuman ring for ~4 months and I really like it! I’ve never owned a smart watch or anything that tracks my fitness/sleep, and this ring is exactly what I was looking for. I love that I don’t have to pay a monthly subscription to access my data/insights. It is also pretty comfortable and I love the caffeine window feature as well.

[This review was collected as part of a promotion.] I bought this ring May 2025 and had the ring for about 3 months until the ring stopped holding battery. The battery would last less than 24 hours in the battery saving mode when it was supposed to last 4-6 days. When I contacted support about it they were very helpful and eventually sent me a completely new ring - hopefully this one lasts. Besides that I have really enjoyed the ring especially the circadian phase tracking. I use the ring as contraceptive so I hope they come out with more features to support that tracking!

Sleep features are good but the activity tracking and calorie burn estimates are not good. The calorie burn on your app barely covers my baseline metabolism and my activity burns almost twice that. Also, I thought the ring would be able to tell me when I’m possibly sick and it has missed that twice.

[This review was collected as part of a promotion.] I bought the Ultrahuman Ring 3 months back. Overall its an excellant device supported by an app which gives a wealth of data and analytics. While comparing with my Garmin watch, i think the Ring shows lower count for steps and deep sleep. Need someone to analyse this. The app connects with Garmin Connect however the analytics of the activities should be correlated with the ring data. I havent found any literature about it

[This review was collected as part of a promotion.] I bought this ring to replace my Apple Watch for a more sleek look without loosing the health tracking benefits! This ring is amazing. I just wish they had a slightly thinner version for women and a more natural gold finish (besides the real gold version), but until then it’s great.

[This review was collected as part of a promotion.] The Ultrahuman Ring Air has completely changed the way I understand my body and health. One of the biggest benefits has been the clarity it provides around my energy levels—I can now pinpoint exactly why I’m feeling tired or off on a particular day, and the app highlights areas I can actively work on to improve. I was genuinely surprised to learn that my sleep quality wasn’t as good as I thought. The detailed sleep insights made me more mindful about my routine and helped me make small changes that have had a big impact. Comfort-wise, the ring is exceptional. It’s light, sleek, and feels like a natural extension of my body. I barely notice it, even while sleeping. I’ve also tested it in pretty rough conditions—during gym workouts, heavy weightlifting sessions, and outdoor runs—and it’s held up flawlessly. Extremely durable. Only downside: The app tends to consume a significant amount of battery in the background, even when the ring isn’t actively connected. I hope future updates address this issue. Overall, highly recommended if you're serious about understanding and improving your health.

It helped me improve my sleep, change some bad habits , I am much more aware of how my sleep influences the whole next day.
