[This review was collected as part of a promotion.] Super comfortable to wearable. Is much much better than wearing a smartwatch to track my sleep. The sleep score is the first thing I look at as soon as I wake up. They keep adding neat little features every week too.

[This review was collected as part of a promotion.] Happy Ultrahuman user here. Couldn't wear sleep trackers earlier but really wanted to see my data. This ring is so light and comfortable and let's me sleep without any discomfort. The sleep data is explained so well on the app, it has become a daily habit to check in on my daily score and work towards a steady and good sleep health.

[This review was collected as part of a promotion.] Honestly, I love the Ring AIR. I received it as a Christmas gift from my husband and all the data output has been amazing; I love the tracking, all the types of data & insights, and the fact it replaces a handful of gadgets into a simplified app! Added bonus is the new additions coming all the time with fertility & cycle tracking, and how the insights play into my pregnancy with resting heart rate & sleep data. The only reason for a drop in the stars is because the battery life/capacity has greatly diminished in the months since I started using it (I received the ring in December, and have used it daily for the last seven months). While at first it lasted a few days at a time, now even in a lower "Chill" mode, I have to charge it multiple times per day to be sure I have enough battery power to track my sleep data overnight.

[This review was collected as part of a promotion.] I purchased the ring in August last year and have enjoyed its features so far. However, I've noticed the battery has been draining very quickly recently, lasting less than a day, which is quite frustrating.

[This review was collected as part of a promotion.] I recently purchased this ring for the sole purpose of improving my sleep and overall health. I do have an Apple Watch as well but find that I can easily sleep with the ring on and do not notice it at all. The health data it collects is extremely accurate especially for sleep! I have been able to make some changes to my night time routine based on suggestions from the app and have improved my sleep. The battery is great and holds up well, I often only charge it when I shower and have never gotten a low battery alert. I can wear it for the entire weekend without charging it which is nice if on vacation. The only reason I gave it 4 stars vs 5 stars is that I found the gold to scratch very easily. Although you can’t tell until you close it’s unfortunate as only a couple months old.

[This review was collected as part of a promotion.] Bought the ring a few months ago and never regretted it , as my sleeping time is all over, with the parameters given by the ring, I took effort to nap when I have a chance and it makes me more productive in my work.

I’ve been using the Ultrahuman Ring Air for 3 months now and I’m hooked. Having previously used the Apple Watch, I found myself abandoning it after a while due to the constant need to charge it. In contrast, the Ring Air lasts 2–3 days on a single charge, powers up quickly, and is far less intrusive — no sweaty wrists or discomfort. The ring is light, comfortable, and effortlessly fits into my daily routine. Every morning, the first thing I do is check my sleep score on the app — it’s intuitive, detailed, and helps me understand where my sleep might’ve fallen short. The health insights are practical and motivating. Overall, it’s a sleek, smart, and reliable companion for anyone serious about improving their health without the fuss of a bulky wearable.

[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.

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.

[This review was collected as part of a promotion.] I bought this at the end of 2024 and it is still going strong. Have had a few issues with the battery, but updates usually fix those issues quickly. It’s comfortable and has plenty of useful features.
