[This review was collected as part of a promotion.] The Ultrahuman ring is a great alternative to the Oura ring. The app is very functional and easy to use breaking information down, unlike the Oura ring. The ring offers important insights into your health allowing you to make subtle changes to your lifestyle for the better. Love the ring and would recommend it to anyone in the market for one.

[This review was collected as part of a promotion.] My husband bought me this for my first Mother’s Day. I have been loving it since. I appreciate the caffeine windows, the recovery score, sleep window and the list goes on. I do notice the battery drains pretty quickly but I do charge it everyday when I shower/do my night routine so it def helps keep it alive. I’m also excited that they added a new parent feature.

Wearing the Ultrahuman ring feels like second nature — it’s incredibly sleek and comfortable. What sets it apart is how intelligently it translates my body’s signals into actionable insights. From sleep quality to recovery patterns, it’s like having a personal coach on my finger. Highly recommended if you're serious about improving your health in a sustainable way.

[This review was collected as part of a promotion.] I bought this ring to help me better understand my sleep and habits that effect it. With slight adjustments to my routines, I was able to get much better sleep thanks to the ring. On the other hand, the ring came with much more detail about my lifestyle and insight into my health. I am very happy with the purchase!

[This review was collected as part of a promotion.] The ring works well and detects things really well, except for the menstrual cycle even though I've been wearing it all the time since December, it still doesn't give the right predictions. And when will the weight loss module be available?

[This review was collected as part of a promotion.] I’m 33, and for the past year, I’ve had a really tough time with sleep. I was diagnosed with mild sleep apnea and kept waking up feeling unrested no matter how early I went to bed. It started affecting my energy, focus, and mood. I didn’t want to rely on machines or meds long-term, so I decided to try the Ultrahuman Ring AIR - and honestly, it’s been one of the best decisions I’ve made. The sleep tracking is super detailed. It helped me understand exactly how much deep vs light sleep I was getting, what my recovery looked like, and how different habits affected my rest. I could see patterns I hadn’t noticed before, like how late-night screen time or eating too close to bed made things worse. One thing I really love is that there’s no subscription - you get all the insights right away, without any monthly fees. The app is clean, the ring is super light (I wear it all day and night), and the battery lasts for several days at a time. I’ve made small changes to my routine based on what the ring showed me, and I’ve genuinely seen a difference. I wake up feeling clearer, and I can tell my body is recovering better. I know sleep can be a personal and frustrating journey, but this little ring gave me back some control. Highly recommend it if you’re trying to take sleep and recovery seriously, especially if you’ve struggled like I have!

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for a few weeks now, and I’m genuinely impressed. It’s sleek, lightweight (you forget you’re even wearing it), and packed with features that offer deep insights into both fitness and recovery. What I love: Form Factor: The ring design is a huge win. It's more subtle than a smartwatch and comfortable enough to wear 24/7—even while sleeping or working out. Sleep and Recovery Insights: The recovery score and sleep tracking are incredibly accurate. It not only tells me how long I slept, but how restorative that sleep was, which helps guide how hard I should push myself the next day. Metabolic Health Tracking: Paired with the Ultrahuman app, the AIR ring gives great context around glucose variability and how your body responds to food, movement, and rest—especially if you're also using their M1 glucose monitor. Battery Life: Lasts around 4-6 days on a single charge. The charging case is also very convenient. Could be better: No live heart rate: It tracks HRV and resting heart rate well, but doesn’t give live heart rate data like some fitness trackers. Size availability: Sizing can be a bit tricky, so make sure to try the sizing kit before ordering your actual ring. Still evolving: Some features are still in beta or rolling out slowly. But the updates so far have been meaningful. Final Thoughts: The Ultrahuman Ring AIR feels like the future of health optimization. If you're into biohacking, performance training, or just want to better understand your body’s rhythms, it’s absolutely worth considering. It’s not just about data—it’s about making smarter daily decisions. Highly recommended.

[This review was collected as part of a promotion.] I had miscarriage and wanted to track my period because I didn’t know when it was coming back after the surgery. One day, I saw the notification saying my period is coming soon. Surprisingly it came on the day! I was very pleased to have the ring!

[This review was collected as part of a promotion.] I've now been wearing the Ultrahuman Ring for a full six months—and here's the latest on how it's performing... I absolutely LOVE it!... It's still a keeper—and I've confidently moved away from smartwatches now.

[This review was collected as part of a promotion.] I’ve had the ring about 5 months and love it. The free app with its updates and insights are amazing. It has helped me strive towards personal goals and share concerns with my doctor. Lightweight, long lasting charge, and durable 10 out of 10.
