Very comfortable
Starting from sizing the Ring prior to getting the ring delivered and connecting to App, all went smoothly.This sizing kit is very useful and easy to use. It includes multiple plastic ring sizers that cover all common sizes, with clear numbers on each ring for easy identification. The quality is excellent, made from durable and comfortable material.

The Most Seamless Way to Track Sleep and Recovery
After using couple of trackers (Amazfit, AppleWatch, PixelWatch), I thought to switch to a device that I can wear easily while sleeping. I found Ultrahuman ring air as an option to try, with its minimalist profile and titanium construction, it felt like the right move for 24/7 tracking without the bulk of a traditional smartwatch. After wearing it for a few weeks, I can say it has exceeded my expectations in several key areas. Battery and Build The battery life is good (not super good when you are on turbo mode), easily lasting 4 days on a single charge, which is a massive relief compared to the daily charging routine of most smartwatches. Despite its lightweight feel, the build quality is incredibly robust. It handles daily wear and tear effortlessly, and I never worry about scuffing it during my day-to-day activities. Seamless Tracking What really stands out is how the ring stays out of the way until you need the data. It automatically detects my workouts with surprising accuracy, so I don't have to manually start a session every time I hit the gym or go for a walk. Intuitive Experience The companion app is a highlight as well. It’s very intuitive, presenting complex health metrics like sleep stages and recovery scores in a way that’s easy to understand and act upon. It provides a holistic view of my health without feeling overwhelming. Final Verdict If you are looking for a screen-free way to monitor your health that is comfortable enough to wear overnight and tough enough for any workout, the Ultrahuman Ring Air is a fantastic choice. It has successfully replaced my bulky watches for sleep and recovery tracking.

Subhuman.. hazardous and traumatic ! Pls read before buying
This review is not a reflection on the features of the ring which I am sure are good , but a fatal flaw in design from which I greatly suffered. Please read the experience below and know very well that there is a small chance this could be you …and think whether is a worth buying such a device I was using the ring for a few days when it got stuck at the bottom of my middle fingers and started to cause discomfort and swelling. As in the case of any normal ring , after failing to pull it off I went to a jeweller shop where they tried a variety of devices which simply could not cut through the strong material. Finally they took out a mini electric saw cutter which also failed to open a ring. The jeweller said that his devices were made for soft metals like gold , and that o would have to find a specialised machine to cut through titanium. It’s now 12:30 am , my swelling is out of control, what am I supposed to do ?? Now frantic with increased discomfort, I messaged customer support on the app ( they don’t have a number) who asked me to proceed to the Emergency Room. However , The doctors in the ER were equally perplexed about how to cut through this material , I frantically asked the support about which tool / power instrument could be used , they had absolutely no answer! There was also the added problem of a battery in the ring , and how to cut through that and with which instrument. Imagine an electrical cutter going through an inflammable battery. My finger by this time had swelled into a baloon, and I had no idea what to do next. We were frantically calling Emergency Rooms at 1 am in the morning , asking them if they had the required tools to break open the titanium band, two of the most premier hospitals in Delhi said that they did not, and only AIIMS had a bone saw cutter that could do the job. We were told that it is a trauma filled experience at AIIMS and decided to try apollo first. Imagine a ring that is Suppose to be a boon to your health becomes a Heath hazard , that simply cannot be taken off. To cut the story short, after multiple tries the ring finally came off at 2:30 am in the morning when a team of skilled plastic surgeons and doctors at apollo hospital finally got the off with the greatest difficultly. Literally 5 full size men had to exert all their cumulative muscle to slowly and painfully cut through the metal using a specialised device. Not only does the ring have absolutely no safety protocol , but there is zero information of how and where it can be cut off during a dire emergency like this. The worst part is the company simply doesn’t care about this hazardous malfunction in the product , after trying to get repeated information from them about the lack of support , guidelines , emergency protocol and statutory safety compliance , they did not even bother call and check on me , and simply offered to replace or refund the ring ( like I would ever wear their ring again). I don’t want anyone to go through , what proved to be one of the worst nights of my entire life, with my whole family sitting outside a ER and the doctor at one point of time bringing out an amputation to try different tools from it. The likelihood is that a situation like this would probably not reoccur with you , but I think you should be well aware of the possible consequences ( however remote ) of using this device. Especially when a company shows blatant disregard to such concerns.

Excellent health insights, comfortable to wear and great battery life
I recently started using the Ultrahuman Ring and my experience so far has been very positive. Quick Highlights: Very lightweight and comfortable to wear, especially during sleep. Excellent analytics and health insights in the Ultrahuman app. Automatic nap detection works very well. Battery lasts around 4 days on a full charge. One of the biggest advantages for me is that I no longer need to wear a smartwatch during sleep. The ring is lightweight, comfortable, and hardly noticeable while sleeping. The analytics and insights provided in the Ultrahuman app are top class. The level of detail around sleep quality, recovery, HRV, movement, and overall health metrics is very impressive. It actually takes some time to fully understand all the insights and how to use them to improve different health parameters, and I feel it will take me a couple of weeks to explore everything properly. Another feature I really liked is the automatic nap detection. Even if I sleep for a short time during the day, the ring detects the nap automatically and records it in the app, which contributes to the overall sleep analysis and sleep score. The battery life is also very good. Once fully charged, I do not need to worry about charging it for around four days, which makes it very convenient for daily use. Overall, it is a great product and a very useful addition for anyone who wants to improve their health routine and understand their body better.

Missed greatness - a beta product which should be stopped immediately !
I took great pride in skipping the Oura ring and the Whoop strap for something INDIAN ! Only to be disappointed - great potential but poorly implemented. Pros - 1. Great details and analysis as a potential (not delivered) 2. Easy to wear 3. Indian tech without any subscription fee except for some advanced features 4. Excellent customer care - replacement happened in three days of the complaint Cons - 1. Poor quality - the Bluetooth modules keep failing - happened on two of my rings 2. Spotty and occasional connection to the app / phone 3. Gets too hot when charging even with a low wattage charger 4. Misses some or even major part of the sleep - happened on two of my devices. Sadly the replacement came through customer care and not through Amazon - where a new replacement or return window would have been open. Now I am stuck with two redundant pieces of tech ! On a positive note - I am proud that an Indian company has done this complicated device. But I am disappointed that they did not spend much on quality control ! Unnecessary spending - maybe Oura or even the cheap Gabit may be better. Hope Ultrahuman recalls the devices and refunds the money. Seems highly unlikely - though they appear passionate about the product it is still a business after all ! Till they rectify folks - let us explore Garmin Venu 3 (working well so far) ; Apple Watch or wait for TCO of Oura to fall.

軽くて、睡眠など細かいデータがみえるので気に入ってます
手首にウェアラブルバンドを使ってたのですが、寝てる時につけているのが嫌だったので、スマートリングにしました、軽くて付け心地もよく、今のところは気にいってます。 スマートリングのブランドとしては、海外ではそれなりに人気があるようですね。 アプリの表示項目は多くて、よくある活動量以外に回復や睡眠は細かいデータが表示されます。 睡眠改善が目的で購入したのですが、朝に振り返ると、前日の活動量や飲酒、寝た時間の影響など良かったり悪かった気付きがあります。 またPowerplugsといわれる追加機能で、睡眠に関連するようなカフェイン摂取の推奨時間帯がみれたり、日光浴の時間記録、スマホのスクリーンタイムの可視化、体内時計のリズムなどいろいろな機能があり、まだ上手く使いこなせてないですが、睡眠の質向上に活かせたらなと思ってます。 バッテリーは3日前後といった感じです、追加機能をオンにしてたり、アプリもよく見るほうだと思うので、仕事中に座ってるときに2、3日に1回充電してます。 リングの中には安いのもいろいろあるようですが、データが数値やグラフで細かく表示され、追加機能もありお値段するだけの高機能なリングだなと思ってます。月額料金がかからないのもいいですね。 睡眠改善と、回復も意識して使い続けたいなと思います。

It's great
It works just fine, the customer service is excellent, size fits alright. The pregnancy mode doesn't really do much apart from telling me how far along I am and which stats can be different... and then the app tells me to pay attention to exactly those stats. Okay.

Wouldn’t buy it from Amazon
I changed it 3 time due to hardware issues Couldn’t return it because i took it from Amazon (though the can be refunded from the Ultrahumain) I would advise to buy it directly from thier shop. Difference 200 SAR. But better support and better refund mechanism
