[This review was collected as part of a promotion.] Very comfortable to wear device and useful insights to fix my habits, especially around sleep. It may not be the best workout tracker, but a good companion for general wellness and have good sleeping and habit around caffeine.

[This review was collected as part of a promotion.] i got the ring in april & i mainly got it to try to conceive but all the other features are AMAZING!! i love the sleep tracking & it’s on the money with tracking my cycle. the only thing that i feel isn’t the most accurate is the step counting, i always feel like i do way more but i will look half through my day at work (as a medical assistant) there’s barely 1,500 steps by my lunch so if you’re looking for that aspect i think a fitbit or apple watch may be better. the sleekness of it being a ring was the other reason to get it. i’ve also started to notice some inconsistencies with the battery life & sometimes it will drain very quickly other times it will take like a week and a half or it takes forever to charge. i cant judge it too hard though because the health rings are new technology so i am so sure it will only get better!

[This review was collected as part of a promotion.] I love the ultrahuman AIR ring! I hate having screens around me so a smart watch was out of the question. After a lot of research I settled on the AIR ring because there is no monthly subscription. I love all of the insight this piece of technology gives me! Sleep, heartrate, and cycle tracking! It has even predicted when im getting sick. The only reason this is not a five star review is because the battery life is not what is advertised. If you want it to last longer than a few days you have to sacrifice tracking.

[This review was collected as part of a promotion.] I love my ring. It helped me so much. I’m still post partum but especially during pregnancy it was amazing. I loved seeeing how pregnancy affected my sleep and stress and even temp. And now I can see how it’s changed after birth.

[This review was collected as part of a promotion.] I really like all the things this ring measures. It's very interesting to watch how what I do in the day affects my sleep that night, from the HR drop to sleep cycles and the length of each phase. Very helpful and interesting, definitely don't regret buying.

[This review was collected as part of a promotion.] I bought the ring first in May, and it stopped working in a week's time. The second time, I received the ring from Ultrahuman as a replacement for the faulty ring; this time the ring stopped functioning in 20 days' time. This has to be one of the worst products that I have bought. Once the ring runs out of battery, the ring will not turn back on.

[This review was collected as part of a promotion.] I am really happy with the ring - I like the sleep stats (which I need to improve), the vitamin D stats, cycle tracking, etc. So much good stuff to improve your health. I like that I don't need to wear a watch or something bulky. It also picks up my walks easily, but I do turn on the workout mode for pilates/etc. Battery lasts like 4-5 days for me with daily workouts.

[This review was collected as part of a promotion.] I bought this ring 2-3 months ago and it has been a game changer. I love this ring. The powerplugs really enhance your experience and you can really understand your body better. The only negative thing I have about this ring is that I purchased the cardio adaptability but I have not seen it provide any actually insights. There is no section for cardio adaptability and no way to really see how it helps you experience. I don’t know if I have to activate my subscription but there has also been no button to do that. Overall great health tracking and sleep tracking.

Ultraring Review: A Small Ring with a Big Edge After two weeks with the Ultraring, it’s safe to say this isn’t just another wellness tracker. It’s a sleek, lightweight powerhouse that delivers deep health insights without the bulk of a smartwatch or the friction of another screen. What I loved: Next-level sleep tracking: Not just duration, but quality, readiness, and recovery cues that actually helped me adjust my routine. Subtle and stylish: It blends seamlessly with my everyday look. No blinking lights, no distractions — just data when I want it. Battery life that holds up: I got nearly a full week on a single charge, which makes it easy to forget I’m even wearing tech. More energy - I follow the caffeine intake and my energy levels in the afternoon are night and day! What could be better: I don't get a period due to surgery and Id love it to suggest potential cycles based on temp so I can still track something.

[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.
