[This review was collected as part of a promotion.] I purchased this ring almost 5 months ago, and could not recommend it more! The app is easy to navigate and has all of your data laid out in an easily-digestible format. I have worn this ring in the pool and during workouts and it had withstood all climates and activities. I use it during Hotworx and Corepower classes and it does not bother me when I use weights.

[This review was collected as part of a promotion.] It's super comfortable to wear. Nice accessory to wear. It's helped me to get better rest by managing my caffeine intake. Helped me to get better rest by going to bed earlier as it was showing me my sleep patterns.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring Air for a while now, and it's become a really useful part of my daily routine. One of the standout features for me is how it tracks and helps me understand my sleep. I get detailed insights each morning—not just how long I slept, but how restful it was, my recovery levels, and what might be affecting it. Another feature I really like is the caffeine window. Based on my sleep data, it recommends the best times to avoid caffeine, which has actually helped me feel more rested and alert during the day. The ring also sends nudges throughout the day, reminding me to move when I've been sitting too long or encouraging me to hit my movement goals. It’s subtle, but effective in keeping me more active. Overall, the Ultrahuman Ring Air is lightweight, comfortable to wear all day, and packs a lot of smart features that support better health habits without being overwhelming.

[This review was collected as part of a promotion.] I bought the ring more than 6 months ago and it is giving me a lot of insights in my daily routine and what I can do to improve my general wellbeing. Specially the app gives you valuable information. A very helpful purchase!

[This review was collected as part of a promotion.] I have used the ring around 6 months Pros: - Lightweight & Comfortable:Only 2.4 grams with a titanium build, ideal for 24/7 wear and sleep tracking. - Accurate Health Data:Detailed sleep stage analysis, HRV, and body temperature monitoring with practical recovery insights (e.g., optimal caffeine intake timing). - No Subscription Fee:More cost-effective than Oura Ring, which requires a monthly subscription. Cons: - Limited Fitness Features:Not ideal for weight training, lacks GPS, and relies on phone syncing. - Complex App:Data-rich but has a steep learning curve, with occasional sync delays. Best For: - Users focused on sleep and stress management. - Those who prefer lightweight, subscription-free health tracking. I think it is excellent for health monitoring but niche in functionality—best suited for specific needs.

[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.] Overall a great product, the app is awesome, user friendly. The readings are helping me to work on maintaining a healthy lifestyle. The only slight issue I have is the battery life, i wish it was a bit longer. But overall, a great product that I have recommended to many of my friends.

[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 have been a customer since Ring R1 for the ease of use for health tracking (especially sleep), and when they launched the Ring Air it just got even better with all the useful functionalities in an even smaller form factor. Just crazy how tech has evolved.

[This review was collected as part of a promotion.] Bought it 8 months ago and enjoy the ring. It tracks all metrics I need. It is a constantly evolving product (from software side) and I’m not using all features yet. The sports are not always spot on for me. But it’s not the main selling proposition. So generally quite happy
