[This review was collected as part of a promotion.] I bought this a few months ago and I really love it. So far it’s been very accurate and I’ve found a lot of the metrics super beneficial in comparison to my watch that tracks similar things. I’d definitely recommend it to anyone.

[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.] Excellent product The Ultrahuman Ring Air collects various metrics related to sleep, movement, and recovery, including heart rate, heart rate variability (HRV), body temperature, SPO2 (blood oxygen saturation), sleep stages, and movement frequency. It uses sensors like a PPG sensor, a 6-axis motion sensor, and a non-contact temperature sensor to capture these signals.

[This review was collected as part of a promotion.] I bought this and wear it everyday for more than a month, the data influence my habbit and help drive my activities, i.e. more move, pay more attention to my sleep habbit. Additional benefit is that I can wear this ring together with my watch collection.

[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 bought the ring about 4 months ago and overall I am quite happy. The insights I got so far helped me to improve my life. The only thing the ring isn't that good at is for fitness plans and how to interpret them. For example if have a running plan you normally improve your mileage over three weeks and then have a deload week with less mileage. But the Ring just tells you that your steps decrease and shows it as negative. So for daily life it's super for fitness interprets you need additional gadgets.

[This review was collected as part of a promotion.] I have a health issue known as Hashimoto's so my health tends to be a bit all over the place. This has been a game changer for me because I am able to gather metrics on what's going wrong with my body due to a specific lifestyle and it has been insanely motivational for me to get things back to normalcy and live a better life. I am also eager to meet my doctor and share the data from the Ultrahuman Ring Air and see if it helps him in recommending further changes.

[This review was collected as part of a promotion.] This ring has truly helped me understand my health to the fullest. I originally purchased to track my sleep, and it has helped me get my health on track by understanding my heart rate, HRV, and stress. I've already set personal records by exercising more and lowering my stress levels and heart rate! The only reason why I took off one star is because the smart alarm in the app is a bit buggy. There have been multiple times the alarm didn't go off even though it was set for the correct date/time.

[This review was collected as part of a promotion.] I love the feeling of knowing how my body is functioning and how it may impact my day. The ring helps me understand when I may need to be more active, get to sleep earlier, and also when best to have caffeine for optimal productivity! I love it!

[This review was collected as part of a promotion.] I bought this ring in January and I absolutely have been obsessed! It looks great with my other jewelry and is very light. I wear it everyday so there are a few scratches on the ring, but it’s not super noticeable. I love watching for new updates and can’t wait to see what else my Ultrahuman Ring is capable of.
