[This review was collected as part of a promotion.] I love this so so much. The insights are incredible and eye opening. I love being able to track my monthly cycle and most times it's on 9/10 times! I love being able to correlate my sleep tracking with caffeine intake. I wish the battery lasted a little longer though but wow, this ring is incredible. Not having to pay for the app to get the basic features is already a one up.

[This review was collected as part of a promotion.] I love the product data and my husband and I have been using it together. However, my purchased my ring and it have connection issues and it never connected properly. ULTRAHUMAN were great at replacing the ring however, after only a month or so of using it, my ring has stopped connecting altogether. It works great for my husband so I’m frustrated it’s happening. However I hope it will get resolved as the app is great!

[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 AIR for a few months now, and I’m really impressed with how accurate and insightful the data is. It tracks my sleep, recovery, and activity seamlessly without ever feeling bulky. The design is sleek and comfortable—I hardly notice I’m wearing it. The app is easy to use and gives me clear, actionable insights that actually help me improve my daily routines. Battery life is great too, and it charges quickly. Overall, this ring has exceeded my expectations and has become an essential part of my wellness journey.

[This review was collected as part of a promotion.] The ring AIR is lightweight and comfortable! I've had it for about a month so far. The data provided is very insightful, but I'm still working through understanding it and how I can change lifestyle to make improvements. I like that there's no subscription needed to access the data.

I have been through 3 rings (original purchase PLUS 2 warranty replacements) in a year in a half due to connection and/or battery issues. These rings suck. My 2nd replacement ring battery won't hold a charge after 7 months. Customer service said they were sending me another replacement… my last one… but when I reached out for tracking number they told me they were cancelling the request.

[This review was collected as part of a promotion.] Stopped sending data to my app after about 2 months of use and the battery dies after a few hours - doesn't last a full night. I tried resetting it, followed all of the prompts, but nothing will fix it. Basically completely useless and a total waste of money.

[This review was collected as part of a promotion.] I have bought this ring because I didn’t want to pay Oura subscription. I have a quite mixed feelings. On one hand I haven’t experienced any problems with battery, pairing or any quality issues. On the other hand the data received from the UltraHuman is way different than from my Apple Watch or Whoop. Also, Czech translation is utter garbage. It seems it was made through Google Translate so it sometimes completely misses the point or even means something different. But they can still fix everything and they are trying.

[This review was collected as part of a promotion.] I received the Ultrahuman Ring as a gift after I stopped wearing my tracking watch. The data and feedback gives me a better feel of how I am doing, the impact on my sleep, how eating/caffeine/activity is impacting my sleep and recovery. I really like the tracking of my workouts and the amount of data.

[This review was collected as part of a promotion.] I've been using the UH Ring Air for approximately two months now, and overall, I'm very satisfied with my experience. Initially, I was expecting a battery life of 3-4 days, but I was consistently getting around 36-48 hours. However, following several software updates, a "Chill Mode" was introduced, which has significantly improved my battery life, even when using Turbo Mode. Unfortunately, I opted for the gold model, which shows scratches more easily; in hindsight, I would have preferred the black version.
