Best smart ring in the market

[This review was collected as part of a promotion.] The Ultrahuman Air Ring has become one of my favourite health gadgets. It feels like nothing on my finger, the build quality is excellent, and the recovery/sleep data has genuinely helped me make better training decisions. The app feels smarter and more intuitive than most wearables, and the daily insights are actually actionable. If you care about recovery without wearing a bulky watch 24/7, this is a no-brainer.

Lots of data!

[This review was collected as part of a promotion.] Overall, I like this product a lot. There are a lot of cool features, data to analyze, and they display it for you in a way that is digestible and not overwhelming. I like the suggestions it gives you based off of different patterns you have. The best thing I like it for is the sleep analysis, and the score it gives me. It gives me insights I haven’t had before! Although now that it is a year out from me having it, I did start having some performance issues like it not tracking data completely.

The best ring ever

[This review was collected as part of a promotion.] I love the fit of this ring! They send you out a measuring ring size kit with multiple basic ones to test for a day to get the perfect fit! It tracks stress aswell as sleep and heart rates! I love the scoring system it does too! I never understood the value for money after testing this and it’s top of the marks

Great Product for price!

[This review was collected as part of a promotion.] I have had my ultrahuman ring for about 5 months now and I love it! I love keeping track of my steps and monthly cycle. My battery life is a little shorter, I have noticed but overall I still love it!

Useful sleep metrics, activity tracking needs impr

[This review was collected as part of a promotion.] I use Ultrahuman ring everyday and most of the data points are reallyuseful, sleep cycle info in particular. However, their activity tracking still needs inprovement i.e. it records steps when I'm riding a motobike and does not pick up other activity like pilates even when I upload them manually. Really hopethis will be corrected with further software updates

Not worth the money

[This review was collected as part of a promotion.] DON'T BUY IT! I bought my ring in the spring and already will not hold a charge longer than 7 hours. I have done multiple resets on the ring, checked all settings to ensure other apps are not draining the battery and still will not hold a charge. Since it will not hold a charge longer than the 7 hours, i cannot even use it to gather data on my sleep, limited thru the day as well and have to charge it just to even track steps. Buy the Oura!
Disappointed

A great tool for health and fitness tracking.

[This review was collected as part of a promotion.] I have found the Ultrahuman Ring to be extremely helpful with giving me insights into my health and fitness. The ring looks great and is lightweight but sturdy. I am happy with the battery life, not had any issues with losing charge. Overall I highly recommend this, it helps with my motivation to get fit and healthy

Connectivity of the ring is extremely poor

[This review was collected as part of a promotion.] I was really excited when I first got the Ultrahuman Ring AIR. It looked great, felt comfortable, and the app experience seemed promising at the start. Unfortunately, that excitement didn’t last long. Within just two months, the ring stopped connecting to my phone altogether. I tried all the troubleshooting steps, even reinstalled the app several times, but nothing worked. It’s disappointing because when it functioned properly, it gave me useful insights into my sleep and recovery. Now it’s just an expensive piece of metal sitting on my desk. I really wanted to love this product, but the reliability just isn’t there.

Sleek & Fashionable Daily Health Tracker

[This review was collected as part of a promotion.] Been wearing this ring daily for the last month and it has become my new favourite health tracker. I mainly use it for sleep tracking as wearing my Apple Watch to bed was cumbersome. It is very comfortable throughout the day and due to the friendly ring sizing guide you get before the ring, is a perfect fit, battery life is great with several modes to choose from and is very durable for everyday use. If, like me, you are a gym goer or are very active with your hands, it would be best to buy a silicone protector for this as it will scratch under heavy use. The only negative with this ring is a potential flaw its long term functionality, when I first received the ring, it lasted less than 24 hours before it would no longer connect or charge. Upon reading online this is a very common issue with these. Support is not the quickest, with long time in between replies. After being told to try several troubleshooting methods including a 4 day battery drain, which did not work, I was sent a replacement. I was without a ring for over 2 weeks which was a little disappointing but the main thing is that the replacement is going on strong.

Good but not great, early adopters go crazy

[This review was collected as part of a promotion.] The initial order process is brilliant; you get a few tester rings (just plastic) to size, which allows you to determine which ring would be best. I would suggest testing different sizes and different fingers to find which one suits you best. The box, way too big for a ring, charger and USB cable. And would rather have had a ring protector than stickers, which I wouldn't use. At first new ring seemed a bit funny to wear. Slightly tighter than when tested, but over time feels better. In terms of functions and features, the best feature has to be sleep tracking. Compared to a well-known smart watch, it gives deeper details in sleep patterns and improves sleep quality. General day-to-day tracking is okay, hr stress, and all the usual data, but that's only in high power mode, which will give you a lot less than 6-7 days as advertised. For that, you have to use chill mode, which reduces functions and limits tracking, i.e, every half hour or so. Step count is way off sometimes, has shown I've done 15k, where other trackers have shown around 5k, and judging what I've done, that would be a lot more believable. Workout tracking - anything cardio not using hands is brilliant, and that's where it stops. I mainly do weights, and it's hit and miss; hr is way off what other trackers are reporting. Coming back to accessories, would have rather had a ring protector for workouts rather than the stickers, The outer ring got scratched in the first few days of wearing it, had to order some but that doesn't seem fair as well as I thought it would Lastly, ring Updates when you check using the dedicated update. There's no update, run ring diagnostics for anything. A magical update appears It's new in tech world, so understand its got a long way to go yet

Insightful health data

[This review was collected as part of a promotion.] The ultrahuman ring is available in multiple sizes, comfortable to wear and provides insightful health data. Available also in several different colours - although fairly similar.

Great features but poor battery life.

I have my ring for around 5 months. Very happy with it in the beginning but starting one month ago, the battery drains very quick. It used to last 3 to 4 days but now I have to charge it 2 times a day, which is so frustrating! I tried the troubleshooting guide, drain it for 4 days and charge it. I'm using the chill mode. I don't know what other solution to try. It's a bad value for the money I spent.
O.D.

Best sleep tracker

[This review was collected as part of a promotion.] I've been wearing the Ultrahuman Ring Air for a while now and I have to say it has completely changed the way I think about my health data. This has to be the best thing to exist for sleep and recovery data. It’s incredibly lightweight and slim and I honestly forget I'm even wearing it, which is crucial for a device you wear 24/7 and especially at night. It's so much more discreet and comfortable than a bulky smartwatch. The data it provides is fantastic. The best part is the sleep tracking and recovery insights. For me, seeing my sleep score and recovery metrics every morning has actually helped me stay active and make good choices to stay on track

Some things are still a miss

[This review was collected as part of a promotion.] Overall happy with the ring. More of a health tracker versus fitness tracker. It doesn’t seem to pick up exercise automatically and if I indicate I’m exercising it often loses connection with the HR seeming very off or inconsistent. I enjoy the sleep and stress tracker. Over the past month, the battery has drained very fast. After charging it’ll tell me to charge again 4-5 hours later. I reset the ring and updated the software without improvement.

Fitness ring helping individuals improve!

[This review was collected as part of a promotion.] I was curious to see how this ring would stack up after using apps to track my steps and fitness. To start, I received a fitting kit to ensure that my finger was the right size, which prevented any discomfort, and the ring appears to be well-made and water-resistant (based on showers and a month of use). The most helpful feature of the ring, which tracks my sleep and active hours, is the recommended caffeine windows and dosage to avoid disrupting my sleep. It also has a lot of other features, such as resting heart rate, and I would suggest this product to anyone who enjoys being active.
