[This review was collected as part of a promotion.] The ring works well and detects things really well, except for the menstrual cycle even though I've been wearing it all the time since December, it still doesn't give the right predictions. And when will the weight loss module be available?

[This review was collected as part of a promotion.] i bought this ring a couple of months ago. however, contrary to expectations mentioned in the booklet I am having to charge the battery every 3rd day. Secondly there are too many health parameters being displayed which are confusing. Otherwise I am happy to be using the product, thanks

[This review was collected as part of a promotion.] After a full year, the Ultrahuman Ring has proven to be more than just a gadget—it’s a health companion. It has helped me become more intentional with my sleep, recovery, and overall wellness. I highly recommend it for anyone serious about optimizing their lifestyle with data-driven insights.

[This review was collected as part of a promotion.] I’ve thoroughly enjoyed my Ring. It’s not too bulky but helps me track my metrics while allowing me to wear my old watches. I’ve also been very impressed with the customer service. This Ring is constantly learning and there will be issues but they’re very accommodating!

[This review was collected as part of a promotion.] I have had this ring for four months now and it has been fantastic. The insights you get when you are tired, not sleeping good, or even not feeling well. This ring helps you understand why you may feel the way you do and gives you hints and tips on how to combat it and do/feel better.

[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.
