[This review was collected as part of a promotion.] I bought my ring approx. 2 months ago. Pros: I really like the design, it's pretty nice and comfy. The user interface is good enough, I can find everything I want easily. The extensions aka. powerplugs are great additions, not to mention most of them are free of charge. My favorite is the circadian rythm tracker, and the smart alarm is also very useful. Built-in breathworks are nice, also free. Exercise tracking is I think as good as you can expect from a ring, plus there are lots of built-in training types. Sleep metrics I cannot compare with other devices or measurements, so I have to rely on what I see in the app, but I feel like they are rather accurate, at least the quantities for sure. Cons: I really wanted to like this ring and I am liking it, but I have to be honest: sadly I'm currently waiting on my third replacement ring. The first stopped charging after a few weeks, the second had a similar problem, but then after a day of trying it did charge up, but then the sleep metrics were gone. The latter was probably a software issue since the metrics during a breathwork session worked, and the sensor diagnosis stated that everything is fine. Regardless of what the actual problem was, it couldn't be used like that. Both lasted for a month, roughly. I only can hope that I will be luckier with the third. If it is really just about luck..

[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.] After having the ring for a couple months, I've enjoyed seeing the information presented for my health. The data is presented in a clear manner and gives some assistance on improvement when necessary. My only negative is the battery. Initially, the battery was lasting a out 5 days between charges. Recently, it has been an every other day requirement. This isn't a major problem and become just another routine activity to plan in my day/evening.

[This review was collected as part of a promotion.] Have had the ring for 1 year now and has been great. Build quality is good, no physical issues. Consistent updates have improved functionality. Some updated caused issues with battery life but subsequent updates have corrected any problems. I have a smart watch and the data between the 2 devices is very similar, with the ring providing a what I feel is more accurate sleep data than the watch.

I’ve been wearing this for about 2 months now and I really enjoy the sleep score and period tracker! It does a really good job paired with my watch and it’s perfect for when I want to disconnect and just have the ring on. I like that it’s light and discrete. Most people just think I’m wearing jewelry until I tell them about it!

[This review was collected as part of a promotion.] I bought this ring two months ago and it has helped me alot from finding out why im still sleeping and when is the best time to consume coffee. I wish the charging was faster but you can't have everything. I'm using it also to track my cycle good investment. I do wish it was not so easy to show the scratch marks.

I am using the ultrahuman ring . Its a great product . Good built, the data and the insight dashboard is very clean and easily readable . I would be happy if I am able to customize my dashboard . For example . When I wake up, I want to see my sleep data first , cz the movement has not yet started. The app should automaticlly move the movement widget on top after it has recorded a certain steps . Another cool feature would be , top 3 metrics to focus on for next one month . there are lots of metric and not every time every day I will have all metric 100% or optimal , but lets say I am a runner (Which I am ), I would want to know top 3 (could be any number) metric to focus on to improve my running goal / recovery score from X to Y . Sort of personal coach or motivator

[This review was collected as part of a promotion.] I bought my ring in June and I’ve been primarily using it to track my sleep! I find it gives very accurate readings and is really good at giving me suggestions and graphing my data. The only reason I gave it four instead of five is that the ring scratches super easily. I have the gold and a lot of it is basically silver at this point. I don’t wear rings around it at all so it’s not rubbing on anything. The battery is okay, I charge it probably every 3 to 4 days. I was hopeful it was going to last longer. Also, often when I go into the app, it takes quite a while to load my data and I have to refresh it quite a few times.

[This review was collected as part of a promotion.] I bought my ring a month ago due to some health concerns and it gave me great insight into why I might’ve been feeling tired and struggled with migraines. I love being able to understand my body better.

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.
