[This review was collected as part of a promotion.] I bought the UH over the Oura ring because there is no monthly fee. So far I am enjoying my ring, I find the sleep data the most inciteful but also really enjoy the caffeine suggestions. The battery life is not as good as I expected, some days it is worse than others. There is an option to preserve battery with a certain setting but it does limit some of the data collected so I haven't played around with that yet. I am interested to see how well it tracks my cycle as I plan to come off of Birth Control in the coming months.

[This review was collected as part of a promotion.] I’ve been using it now for 2 months and am really happy overall with my experience. As a runner, I find all of the cardio age and vo2 max statistics really helpful and it’s been great to see them changing the longer I use the ring. The battery is good, I charge it whilst I’m at my desk every few days or so and it’s relatively fast to charge to full battery. My only reason for not giving it 5 stars is the period tracking. I was under the impression that as it measures your body temperature it would predict cycle outcomes based on this, not just 28 days. As someone with an irregular period, if it is late, the app just says that my period is in an unknown phase. It seems to basically be their own version of an app such as flo. I don’t find it to be any more accurate, despite the body temperature measuring.

[This review was collected as part of a promotion.] I bought this ring in November and overall it’s fine, but I don’t think it’s super accurate. If I charge it overnight, it will still say that I slept and gave me a sleep score but I wasn’t wearing it. This has happened multiple times. It’s nice to wear and not bulky on uncomfy. Also I think the goals/metrics are mostly for walking, I don’t think it tracks other activity well. Also my charge will only last a day if I try and log any activity.

[This review was collected as part of a promotion.] I have had the ring since November 2024. The hardware seems solid! The app has improved over time, but I do feel like the data should give more actionable insights rather than being so broadly informative.

[This review was collected as part of a promotion.] Bought this a few months back for tracking my sleep. So far works awesome. I was able to see my sleep pattern and the app suggested something around not having heavy meals before I sleep. Steps counts are also good.

[This review was collected as part of a promotion.] I find it very inaccurate with sleep and heart rate. It told me for weeks my heart rate was 42bpm when clearly it was double. When I tried to finds someone to call to repair. This was impossible for the average person. Its having trouble charging as well. Some days it lasts 1 day before it requires a recharge

[This review was collected as part of a promotion.] I’ve been using the ring for about two months now, and overall I’m very happy with it. The ring hasn’t discolored at all and still looks like new. It’s very comfortable to wear, even while sleeping or during workouts. I use it regularly for strength training, and it never gets in the way or feels uncomfortable. It’s especially great for sleep tracking — very accurate and insightful. One downside is that you can’t see things like calorie burn in real time; you only get the data afterward. Also, the battery life is a bit shorter than advertised. I usually get about 4 to 5 days per charge. Still, compared to a smartwatch, this is already a big improvement for me. All in all, I’m really satisfied with this ring and would definitely recommend it for anyone looking to track sleep and activity in a more subtle way.

[This review was collected as part of a promotion.] I bought it about 6 months ago, I still wear this ring every day to track various aspects of my health, especially my sleep. I usually find wearing a watch annoying, so this is a better alternative. Plus, it also serves as a fashion accessory.

Ultraring Review: A Small Ring with a Big Edge After two weeks with the Ultraring, it’s safe to say this isn’t just another wellness tracker. It’s a sleek, lightweight powerhouse that delivers deep health insights without the bulk of a smartwatch or the friction of another screen. What I loved: Next-level sleep tracking: Not just duration, but quality, readiness, and recovery cues that actually helped me adjust my routine. Subtle and stylish: It blends seamlessly with my everyday look. No blinking lights, no distractions — just data when I want it. Battery life that holds up: I got nearly a full week on a single charge, which makes it easy to forget I’m even wearing tech. More energy - I follow the caffeine intake and my energy levels in the afternoon are night and day! What could be better: I don't get a period due to surgery and Id love it to suggest potential cycles based on temp so I can still track something.

[This review was collected as part of a promotion.] I received the Ultrahuman Ring AIR as a Christmas gift, and it’s been a total game-changer in how I approach my health and daily routines. One of the biggest improvements I’ve noticed is in my sleep—seeing my recovery and HRV scores every morning has made me much more intentional about winding down properly at night. I’ve also become more mindful of how my habits (like late-night scrolling or late meals) affect my sleep quality. What surprised me the most is how much it’s helped with focus and productivity. Knowing when I’m in an optimal state for deep work versus when I need to recharge has helped me avoid burnout and stay sharper throughout the day. Overall, I feel more in control of my body and mind. The data is not at all overwhelming and after awhile using it, I barely notice it on my finger anymore. One thing I do recommend is getting a silicone cover for it as mine has scratched a little bit from everyday use.
