[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.

[This review was collected as part of a promotion.] Been a month and a half since I’m using it. This has definitely been transformational for me because a lot of the patterns that my body portrayed are now finding logic because of the ring. I have changed my sleeping habits, eating time, etc. The only issue I feel right now is charging. I’m never able to charge it to 100% because the only time I take off the ring is in the morning for about 40-50 minutes before I’m ready to leave for work. Other than that it is GREAT!

[This review was collected as part of a promotion.] I have been using Ultrahuman ring for a about a year. When I first started, my average sleep score was in the 60s. Now, it’s consistently above 80. This improvement has significantly boosted my energy levels and overall quality of life. This device is designed for long-term impact, not fleeting alerts. It's a quiet, consistent companion that has truly helped my wellness.

[This review was collected as part of a promotion.] Overall, I am really enjoying my Ring AIR. It’s pretty accurate and I enjoy all of the features and ‘power plugs’ that are available. I love that you don’t have to pay a monthly fee for the app, that’s why I chose this option instead of the Oura. I have had some problems with the ring tracking and syncing both my sleep and activity at times, which is a little frustrating. I’ve contacted support through the app and each time they’ve been helpful! I’m happy with my purchase and would recommend!

[This review was collected as part of a promotion.] I have been wearing the Ultrahuman Ring AIR for 8 months and prefer it over the Samsung Galaxy Ring, it offers so much more insights about my health on how I should manage my sleep and caffeine intake, the power plugs are awesome, and it is super comfortable to wear all day unlike the Galaxy Ring that has sharp edges and an uncomfortable fit. Definitely recommend it.

[This review was collected as part of a promotion.] I have loved every minute of having my ultra human ring! I purchased mainly to track my fertility specifically my temperature, but it has been so beneficial in other areas as well. Love love this device!

[This review was collected as part of a promotion.] I’ve been using the ring for about a month now - and I love its form factor. It’s so comfortable to have on and UH also has a superior way of insight delivery on their app. The metrics are super traceable and intuitive to understand - I also love the tags feature which is unlike WHOOP’s journal feature that u I find quite annoying. It also looks amazing and RT goes with all my outfits

[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.] I bought this to replace my Apple watch, as I didn’t like the look of the watch. I’m a real data freak and love all the things it can measure. It looks nice on the finger. What I like most about Ultrahuman is that they constantly are improving and add new features. Sometimes the ring won’t connect in the app which leads to me not being able to check my data. The connection is a bit fiddly sometimes. It did scratch with everyday use, bus I’m not too precise with my day-to-day handling.

[This review was collected as part of a promotion.] Overall i am mid happy with it, but I bought to use the period tracking and it still says in calibration. Moreover it is not possible to add an activity afterwards bc it just says no data, I can only add it if it auto tracks it. The sleep tracker is also off, it makes no sense the amount of deep sleep I get
