[This review was collected as part of a promotion.] The ring itself is good and looks nice. The issue with the product is the partnered App, as it is very unstable. There are times when it syncs well, there are times that it wont and requires constant restart. I wish they can embed auto sync.

[This review was collected as part of a promotion.] I’ve been testing the Ultrahuman Ring Air, and it’s quickly becoming a valuable tool for monitoring recovery, sleep, and overall readiness. The design is sleek and comfortable, making it easy to wear around the clock without disrupting daily activity or training sessions. What stands out most is the depth of insight provided. HRV tracking, sleep stage analysis, and metabolic health markers are presented in a way that’s both actionable and easy to interpret. The seamless integration with Ultrahuman’s ecosystem adds another layer, allowing for a more holistic approach to athlete monitoring and personal performance optimization. For anyone serious about understanding their body’s response to stress, recovery, and training load, the Ultrahuman Ring Air offers a level of precision and usability that’s hard to match. I’m excited to continue exploring how this can support athletes at the elite level.

[This review was collected as part of a promotion.] I bought this ring around 2 months ago. I am definitely satisfied with the software and functions of the ring. What I am not really satisfied with is the physical aspects of the ring. Its really chunky and it leaves marks on fingers after wearing it for too long. I have to change the ring from one hand to other every day.

I’m really happy with my Ultra Human Air Ring and wear it every day. It has given me a lot more insight into my sleep, I now have a better understanding of my overall sleep quantity and the different sleep phases. Additionally, the ring helps me track my stress levels and I can visually see when I need to take it easy and slow down, which is really useful. I’ve only just started tracking my cycle, so I’m still unsure about its accuracy, but the data looks clear and organized. The ring is comfortable to wear. It’s a bit discolored now, which I find a little disappointing, but I understand since I wear it all the time. Overall, I’m really happy with it and would definitely recommend it to anyone looking to gain more insight into their lifestyle. The battery life is great too!

[This review was collected as part of a promotion.] I bought this ring 2 months ago and I’ve really liked it. I really enjoy the circadian rhythm feature, the steps and the sleep index. I would like to be able to add a dish and its macros as I’ve have not been able to do so. The ring also does not take into account in the sleep debt a night where you do not sleep. Overall I think this is a great and ver useful product and I’m really happy with my purchase.

[This review was collected as part of a promotion.] I’ve been wearing the Ultrahuman Ring AIR for a while now and I’m really enjoying it. It’s comfortable to wear and although it takes some persuasion to get on and off, it feels secure once it’s on. The green light flashing when it’s measuring my heart rate is a cool reminder of how much tech is packed into such a small ring. Battery life is solid too – I only need to charge it about once a week and it’s fully topped up in an hour or two. The sleep tracking feels accurate and has made me appreciate the quality of my sleep rather than just how many hours I get. It doesn’t always agree with my Fitbit or Pixel Watch but the insights and notifications like “something kept you up” or “was it hot in your bedroom” have been surprisingly helpful. The app is extensive and it’s great that all the features are included with no subscription. I’ve only scratched the surface so far but for anyone into health tracking this is a really capable and sleek device.

[This review was collected as part of a promotion.] Initially was great very quickly went down hill. Has struggled with connectivity and battery life, dies in a day and a half maybe two days sometimes on chill mode. It constantly wouldn’t track my sleep data and would show 2-3 hours of a 8 hour sleep. I have already requested a refund for the clearly faulty product. If you can fix these issues I’d be interested in continuing to use Ultrahuman as I do believe the product and what you are towing to achieve

[This review was collected as part of a promotion.] This ring was gifted to me for mother's day. It was a surprise, and i wasn't sure it was going to be for me, but I love it! I love how simple the tracking is - no bulky watch to wear - only some beautiful jewelry.

[This review was collected as part of a promotion.] I really like the ring, it comes with several reports and great insights on cardiovascular status and brain health. The fertility/ovulation tracker is interesting and why I got this product, but I wish it could be developed further and become a central part of the app instead of just a plugin. There's another plugin on caffeine consumption window, which is interesting but not necessarily accurate. For instance, I know I am a fast metabolizer, can drink coffee or energy drinks just before bed, but the ring is not capturing that. Otherwise I am looking forward to the updates!

[This review was collected as part of a promotion.] I purchased this ring almost 5 months ago, and could not recommend it more! The app is easy to navigate and has all of your data laid out in an easily-digestible format. I have worn this ring in the pool and during workouts and it had withstood all climates and activities. I use it during Hotworx and Corepower classes and it does not bother me when I use weights.
