Great piece of hardware!

[This review was collected as part of a promotion.] I am completely satisfied with my Ultrahuman Air ring. I bought it a few months ago and I can already feel a noticeable shift in many things. My sleep has improved. I know when to rest more and when to exercise more. It has also improved my caffeine intake, which has had an effect on my sleep. Great piece of hardware!

Love the heart age health!

[This review was collected as part of a promotion.] I absolutely love the ring it’s helped me improve my sleeping pattern and help with my overall focus on my health. My only issue is the charging dock, I don’t know why when I put it on the dock I have to keep moving it to keep it charging. Don’t know if I’m doing something wrong or what.

good features but could aways improve

[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!

Ultrahuman Ring Air is very helpful!

[This review was collected as part of a promotion.] I love my Ultrahuman Ring Air. It provides me with great insight on a lot of health data. It also tells me how to improve my scores when they are not the best. One of my favorite things about the ring is my sleep score and how that affects my caffeine window.

Great companion!

[This review was collected as part of a promotion.] Bought the ring avout 2 minths ago and it gives me most if the details I was looking to track my sleep. I’d be looking for an improved exercise tracking functionality in the future. App is complete and insightful.

Honest review

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for a while now, and overall - it’s pretty solid, especially when it comes to sleep tracking. It actually helped me become more aware of my sleep habits, and over time I started making better choices because of it. So yeah, it’s great if you’re trying to improve your recovery or just want to feel more in control of your daily rhythm. The ring also tracks HRV and VO2 max, which is cool – but honestly, I’m still not 100% sure how it calculates those numbers. The data looks impressive, but it’d be nice to understand exactly where it’s coming from. Now the not-so-great part: training tracking. If you’re expecting super accurate heart rate during workouts, you might be a bit disappointed. It’s okay for general trends, but it’s not super precise yet - especially if you’re doing intense or fast-paced workouts. Hopefully they improve this with updates. Bottom line? It’s awesome for sleep and recovery. Still a work in progress for workouts.

Highly recommend

I’ve had my ring for a month now and it’s dramatically improved my sleep and recovery. The caffeine window is a helpful feature and the movement score makes me more likely to get extra steps in. I’ve found the ring great for tracking runs and your zone training but the only con so far is that I have to remove the ring when I am at the gym so it doesn’t scratch.

Great Health Insights

[This review was collected as part of a promotion.] Been using the Ring Air size 10 for more than a month now and the ring provides a substantial insight into the health parameters of the day. The app is concise and informative with all the necessary information right front and centre leading to an enjoyable experience while using the app. I particularly love the caffeine window and the sleep score information, both of which have greatly influenced by actions throughout the day to get the best possible sleep and rest required. The only thing that maybe improved in the long run is the battery life. Currently, on a full charge, the ring lasts for about 4 days.

Superb sleep tracking for improving your sleep

[This review was collected as part of a promotion.] Bought the Ring AIR about five months ago, mainly because of the no-subscription business model, and the other reason was for sleep tracking. It has been amazing to see trends over time, and the ability to easily access all the data as a csv file has been really helpful. Only a few days ago I decided to improve my sleep with supplements, and after four days of taking two of them (magnesium glycinate and L-theonine) I've seen measurable improvement. Having data regarding sleep stages, sleep time and other metrics like HRV and temperature drop has been super-helpful. I wear the ring all the time, and am happy to start tracking my workouts now as well. Highly recommended!

Great features

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring AIR for a few weeks now, and the difference in sleep quality and recovery is night and day. The real-time biomarker insights (especially HRV and skin temperature) gave me more control over my routine and helped me make smarter lifestyle choices. It’s not just a tracker - it’s a personal performance optimizer. Looking forward to more firmware upgrades and continued improvements. Great product, strong ecosystem.
