[This review was collected as part of a promotion.] I’ve been using it for three months now, and there are some things that I like and some things that I don’t I find that the heart rate tracking, especially when I’m logging a workout is very inaccurate. I’ve even compared it with results from another fitness tracker of mine that I’ve worn at the same time to confirm. The sleep tracker is probably my favorite feature.

[This review was collected as part of a promotion.] I’ve been testing the Ultrahuman Ring Air, and it’s quickly becoming a valuable tool for monitoring recovery, sleep, and overall readiness. The design is sleek and comfortable, making it easy to wear around the clock without disrupting daily activity or training sessions. What stands out most is the depth of insight provided. HRV tracking, sleep stage analysis, and metabolic health markers are presented in a way that’s both actionable and easy to interpret. The seamless integration with Ultrahuman’s ecosystem adds another layer, allowing for a more holistic approach to athlete monitoring and personal performance optimization. For anyone serious about understanding their body’s response to stress, recovery, and training load, the Ultrahuman Ring Air offers a level of precision and usability that’s hard to match. I’m excited to continue exploring how this can support athletes at the elite level.

[This review was collected as part of a promotion.] I find the ring such a helpful tool to keep track of my sleep and encourage me to look after myself. It helps me focus on my sleep and my self care generally. Gently reminding me when to move more or lay off the caffeine. The main thing it has helped me with is getting sunlight first thing in the morning to help regulate my circadian rhythm. I feel more in control of my habits as I can check in with the app anytime to see what my body is dealing with.

[This review was collected as part of a promotion.] I got this ring for Mother’s Day and I love it. My only gripe is this is my second ring because my first one wouldn’t connect anymore and there have been a few times where I’m in workout mode my ring doesn’t register my heart rate. Overall I do love all the data the ring provides.

[This review was collected as part of a promotion.] Since becoming a first-time mom, managing my sleep has been a challenge — but the Ultrahuman Ring has made a huge difference. It’s so light and comfortable I forget I’m wearing it, and it gives me super useful insights to help prioritize rest without any extra effort.

- - : Autonomy / The sport activity apps could be more friendly and usefull. for example the "3 2 1" timer is really not necessary for me / the ring shape could be thiner + + : the ring make you think about yourself more frequently, it allows yourself to have a really good focus on simple things like sleep schedules or coffee time. Also, after a lung issue, the oxygenation % is reassuring even if not 100% accurate.

[This review was collected as part of a promotion.] If you’re looking for a wellness wearable that actually keeps up with your life, the Ultrahuman Ring AIR 2 is it. I’ve been using it daily and honestly — I’m super impressed. My absolute favorite part? The battery life is next level. Like, for real… it lasts for dayzzzz. I’m not constantly charging it, which makes it so easy to just wear and forget — until it reminds me that my sleep score needs work 😅. It’s light, comfortable, and tracks everything from sleep and recovery to movement and HRV without feeling bulky or distracting. The insights are clear and actually useful — not just data for data’s sake. If you’re into optimizing your health but don’t want a device that screams “fitness tracker,” this ring is a low-key powerhouse. Highly recommend. 👏

[This review was collected as part of a promotion.] This is one of the best purchases I’ve ever made. I really love the ring — it looks great, feels great, and works reliably. What I value most is that the Ultrahuman Ring does not require a subscription. That was a dealbreaker for me — I didn’t even consider rings like Oura. I’m happy to pay significantly more (even 30% more) for a device if it offers strong baseline functionality with no recurring fees. Please never move core features behind a paywall — that would be a reason for me to stop using it. I’m strongly against subscription models as the only entry point. I’m fine with paying for optional add-ons — that model makes sense and I’m even considering a few. One small improvement I’d love: slightly longer battery life, maybe +1–2 days. Otherwise, amazing product.

[This review was collected as part of a promotion.] "I’ve been using the Ultrahuman Ring AIR for about two months now, and I chose it over other smart rings because of its impressive hardware and intuitive software. One major plus is that it works seamlessly with both iPhone and Android, which made it a versatile choice for me."

[This review was collected as part of a promotion.] This was a great purchase! Thanks to the caffeine window feature, I stopped drinking coffee right after waking up and started feeling more energized during the day. It also motivates me to stay more active during the day, and offers many interesting insights into my health. I really like that they are rolling out new features all the time!
