Sleep tracking
on July 3, 2025
Posted by: Santosh
from Dubai
Gender:Male
[This review was collected as part of a promotion.] I was sleeping 7–8 hours most nights, but waking up feeling like I hadn’t slept at all. I’d scroll through sleep tips online, try magnesium, meditation, no screens before bed—you name it. Nothing really stuck, because I didn’t know what was actually going wrong.
This ring changed that.
It didn’t magically fix my sleep overnight, but it finally gave me a way to see what’s happening while I’m asleep. Turns out I wasn’t getting enough deep sleep, and my recovery scores were way off after high-stress days, even if I hadn’t worked out. The HRV data, resting heart rate, even skin temperature started to paint a fuller picture of what my body was going through.
I also started noticing how my sleep improved when I ate earlier, skipped alcohol, or took a proper wind-down routine seriously. Before, it all felt like guessing. Now it feels like learning.
The ring itself is great—super light, looks good, and I barely feel it at night, which is huge. I didn’t want another thing buzzing on my wrist.
Honestly, I bought this ring because I was tired of being tired lol. But it makes a huge difference in my life.
I would recommend this to a friend!

My personal commitment partner to wellness!

[This review was collected as part of a promotion.] Heart disease runs in my family, and even though I try to stay active, I’ve never really known how well my heart is actually doing. Not just on the outside, but internally—like how fit it really is.
This ring has been surprisingly helpful. The Cardio Age feature kind of freaked me out at first, but it was also a wake-up call. Seeing that number was a good push to take things more seriously—and what's cool is that I could actually see it improve a bit after a couple of weeks of better sleep and more consistent workouts.
The VO2 Max reading is another feature I didn’t expect to care about, but now I check it way more often than I probably should. It’s satisfying to see it climb, even slowly. And cardio adaptability is probably what I’ve appreciated the most. It tells me how well my body is bouncing back from stress or workouts—and for someone with my family history, that feels like gold.
As for the design, honestly, I’m not a huge fan of chunky wearables, so I was relieved that the ring looks clean and minimal. It doesn’t scream “fitness tracker,” which I love. Super light, too—I forget I’m wearing it most of the time.

TL;DR: If you’re someone who’s trying to understand your heart better—not just count steps—the ring gives you data that actually matters. Especially if, like me, you're trying to stay a step ahead of genetics.

[This review was collected as part of a promotion.] I am very happy with my ring! It’s comfy, the app is easy to use and gives tons of info, there’s a section for breath work but I’ve yet to use it. Really cool!

A total game-changer for my weight loss journey
on July 3, 2025
Posted by: Brangel
from Los Angeles, CA
Gender:Female
[This review was collected as part of a promotion.] I’m a middle‑aged woman who started at around 200 lbs, and the Ultrahuman Ring AIR has been a real game changer in my weight loss journey. It’s lightweight and comfortable - you barely feel it - and it gives clear, subscription‑free insights into my sleep, recovery, and daily activity. Seeing how well I slept and recovered each night helped me adjust my evening habits and push just the right amount during workouts, which made losing those first pounds feel manageable and sustainable. The ring lasts several days on its battery, the app is clean and easy to use, and it really felt like having a wellness coach on my finger.

[This review was collected as part of a promotion.] Ultrahuman Ring Air has been a lifesaver in tracking my sleep as I am not able to sleep with a watch on. The sleep, caffeine, and recovery insights are very useful in improving my quality of life each day.
Also, the build quality and look is great!

[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.
