[This review was collected as part of a promotion.] With this single device, you can accurately monitor all the essential health metrics typically tracked by a smartwatch—such as calories burned, sleep analysis, blood oxygen levels, heart rate, and skin temperature. What sets the UltraHuman Ring Air apart is its ability to go one step further by offering personalized advice and tips to help you improve your daily lifestyle habits. I started using this ring around March, and since then, its features have been continuously updated. New functions like “Brain Age” and “Pulse Age” have been added. It’s a smart ring that continues to evolve every day. スマートウォッチでわかること（カロリー、睡眠分析、血中酸素濃度、心拍数、皮膚温度）など基本的なことは、これ1つで正確にデータを見ることができます。　UltraHuman Ring Airはさらに一歩踏み込み、日常の生活習慣を見直すためのアドバイスやTIPSを提案してくれる点が素晴らしいです。 このリングを使い始めたのは3月頃からですが、日々機能がアップデートされており「脳年齢」「脈拍年齢」など新たな機能が追加。日々進化し続けるスマートリングです。

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for several weeks now, and I can confidently say it’s become an essential part of my health and fitness routine. What sets it apart for me is how seamlessly it tracks sleep, recovery, and overall readiness without being bulky or intrusive. I wear it 24/7, and often forget it’s even there. Sleep tracking has been especially impressive. The insights into my deep sleep, REM cycles, and HRV have helped me make meaningful changes to my bedtime routine. I’ve noticed that on nights where I prioritize wind-down, my ring reflects the quality improvement—and I feel it too. The daily recovery score is one of my favorite features. It helps me decide whether to push hard in the gym or take a lighter day. It’s like having a coach who reminds me to listen to my body without the guesswork. I’ve noticed better energy levels and fewer slumps since I started using the ring to guide my training intensity.

[This review was collected as part of a promotion.] Initially everything worked wonderfully, then I noticed ongoing issues with the charge. It takes a significant amount of time to charge, then the battery drains very quickly. In addition, it has just not worked all day today and is prompting me to complete a factory reset, losing all my data. The dashboard is not showing anything or collecting any info. It often disconnects while I workout and will not let me end my workout session. At first the sleep features with the caffeine windows performed amazing and were game changers.

[This review was collected as part of a promotion.] I bought my Ultrahuman Ring Air last year 2024 end of January and I have been very pleased with my ring. I was initially torn on whether to get this ring or Oura, but didn't like the subscription for Oura so it was no brainer to get this ring. The ring constantly goes through updates which is great. I got this ring mainly to keep track of my sleep, but now I'm pretty obsessed with the data that I get for my daily reports of movements, workouts and recovery, etc. and I find myself trying to improve it before the end of the day. I did have problems with charging as it would overheat after a few mins. They have noticed this and contacted me and have sent me a new charger free of charge which is amazing. This ring is definitely worth it if you're trying to keep track of your health compared to the other rings and worth the investment for me.

[This review was collected as part of a promotion.] The Ultrahuman has been so helpful in helping me track my sleep. I have a seizure disorder that is impacted by sleep and stress. I like being able to see the sleep deficit and will try to build a nap into my day when I have one. It also holds me accountable when I skip workouts by telling me at the end of the week how much less active I was in comparison to the week before! It's been great and i recommend it to everyone interested in getting a ring.

[This review was collected as part of a promotion.] Bought my ring at the beginning of the year as an add-on to my Apple watch. Am fairly happy with all the features and measurements. I do find that my Apple watch workouts aren't always syncing correctly with the UH app. So that’s a bit annoying. Also not happy with the Tesla integration feature. But all in all, readings and pretty good and keeps me on track.

[This review was collected as part of a promotion.] I've bought the product in July 2024 and have been wearing it almost 24/7, locally and also for overseas holidays. Everything is great from the sensors, comfort, and also current and new features released regularly. The only downside is that the battery which could last about 6 days when I first bought it now could only last at max 3 days. I've not change any power or battery management settings so i guess the battery drain could be from the new features etc. Overall still a great ring.

[This review was collected as part of a promotion.] I absolutely love my ring!! Getting such an in-depth look at my daily metrics and what affects my sleep has really helped me prioritize better habits and make sleep more important to me. It’s very accurate, super easy to use, and I have had literally zero technical issues. Love this ring so much!!!

[This review was collected as part of a promotion.] I received this a few months ago and I’ve enjoyed using the ring so far. Some of its features are extremely accurate as it gets to know your body. I’m looking forward to more features in the future!

[This review was collected as part of a promotion.] I bought this and wear it everyday for more than a month, the data influence my habbit and help drive my activities, i.e. more move, pay more attention to my sleep habbit. Additional benefit is that I can wear this ring together with my watch collection.
