[This review was collected as part of a promotion.] I bought it a few months ago. It works mostly like expected but I have some issues. When working out it takes forever to connect when starting the work out and ending it. During the night the app sometimes doesn’t work through the night and my alarm doesn’t go off. However, the menstrual cycle prediction is very good.

I bought the Ultrahuman Air approximately 2 months ago and I'm content with it. I haven't had any problems with it so far. My only complaint is that when I bought the ring, it was advertised with a battery life of up to 6 days. I can go about 3-4 days in between charges and I have it on chill mode. I have the raw titanium color and it gets scratched pretty easily. Other than that, I love the ring.

[This review was collected as part of a promotion.] Love this product - love the colour options and the fact that this is super insightful and that it’s so light. I feel really good about the metrics it’s given me over the last month as well and they’re helping me move more and rest better

[This review was collected as part of a promotion.] I love it, its really helped me optimise my sleep and health and moniter my walking and stress and not being embarassed of a clunky applewatch i can wear the ring any occasion even wore it to a wedding and had compliments ! I only wish the implant was an option when informing the ring of your contraception for period tracking

I bought my ring secondhand but brand new. The person I bought it from told me that they sent their original ring back because the battery life significantly dropped after just over a month of use. Ultrahuman sent her a brand new ring which I then bought from her - and I've had the same experience. The battery used to last several days and now it maybe lasts a day and a half. I've only had it for a few months. Battery life aside, I do enjoy exploring the information provided, particularly my sleep scores, cycle, and movement throughout the day.

[This review was collected as part of a promotion.] I’ve been wearing my Ultrahuman ring for about two months now, and it’s ok. I don’t get very accurate heart rate data when working out. I tend to wear my Apple Watch for workouts, spin class and walks or runs which defeated the purpose of my purchase. It is comfortable and I like the look of it.

[This review was collected as part of a promotion.] The Ultrahuman Ring Air is an impressive concept with solid potential, but its accuracy varies depending on what you’re tracking. Here’s my experience: What It Gets Right: • Resting Heart Rate: Very close to my Apple Watch readings, which is reassuring. • Sleep Temperature: Reliable for tracking temperature shifts during the night. Where It Struggles: • Sleep Tracking: Sleep duration and stages feel inconsistent. I can wake multiple times in a night, yet the ring reports a full 7 hours. It’s better for spotting overall trends rather than precise sleep scoring. Other Highlights: • No Mandatory Subscription: A big plus compared to many competitors. There’s a fee for deeper insights, but core data is accessible without ongoing costs. • App Insights: The guidance on recovery and health trends is practical and helpful. • Comfort: Lightweight and comfortable; I hardly notice I’m wearing it. Bottom Line: This ring is a great tool for trend tracking and recovery insights, especially if you want a screen-free experience without a subscription. Just know it’s not perfect yet for detailed sleep or workout tracking. The good news? The company is actively improving the product, so accuracy may get better over time.

The ring itself looks good and is lightweight so it is easy to get used to having it on. I bought this after researching that it does the same things as competitors at a more reasonable price. However, I do find myself skeptical about the data it captures specifically when it says I have done a lot of walking during times I have been stationary, but it doesn't capture when I have just played a sport or other activity very well. That said, I do find that how I generally feel after I sleep does coincide with my sleep scores most of the time.

[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 have had this ring for about 2 months now and love it. I am not usually super into this stuff, but the insights are unreal. I mostly wanted it to count my steps and help me with my sleep, but it does so much more like my stress levels, caffiene, and insights on my cycle. I also thought it would be uncomfortable but I barely notice it, and the only ring I wear is my wedding rings.
