ULTRAHUMAN Ring AIR – Sleep and Fitness Tracker, Smart Ring for Men and Women, No app fee for standard features, Up to 6 days battery life (Size 7)

best investment of 2025! looks and feels amazing on, very functional - you can track so much on it in real time. especially good if you struggle with sleep as it gives you detailed insights. i managed to get it on a black friday deal (£232) so the value for money was amazing! only con of this ring is that it does scratch easily but this can be mitigated by getting a cover for it.

I’ve been using the Ultrahuman Ring for a few weeks now, and it has made a real difference to my daily routine. I love how accurately it tracks my activity and sleep, and the insights have helped me improve my focus and rest. It is incredibly durable, even through intense gym sessions and weight training and comfortable to wear, reliable, and definitely motivates me to stay consistent with my health goals.

So far so good. Ring functions well with a few caveats. The times showing wake up etc are generally inaccurate. For example today I was up at 0458 and the ring indicated 0809. This then throws off some of the other stats. Additionally, I would like some more explanation or simplification of the stats and figures in the app as I am quite new at this. The ring looks good but come off periodically while I am doing things around the house. Perhaps I should have sized differently but wear it on my index finger by choice. May have to replace it for different size. Generally I am satisfied but would really like a less complex app UI for us newbies. Will update after further usage.

I am happy with the functionality of this ring. The stats mirror fairly closely to my Apple Watch in terms of sleep. Steps are not at all accurate though. The app provides lots of information, which I love, although it could be overwhelming for some. That said, it breaks it down well and gives some well presented information The ring is well made and solid, and looks good. So far I am very happy with the product.

I wanted to like the Ultrahuman Air Ring, but my experience over the last 12 months has been extremely disappointing. In total, I have had four rings within a year. Three failed due to battery issues, and the fourth lasted just four weeks before developing Bluetooth connectivity problems, making it unusable. This level of failure suggests a serious reliability and quality control issue. (only three in the photo as the fourth has now gone back to Amazon for a refund. What concerned me almost as much as the hardware failures was how the situation was handled. After the fourth failure, I was offered a second-hand refurbished ring as a “goodwill gesture”, despite the ongoing faults and the product clearly not being of satisfactory durability. This offer was made while my consumer rights were initially ignored. Only after I explicitly stated my UK consumer rights and insisted on a refund did the company eventually concede. While the concept of the ring is excellent and the data is useful when it works, a wearable at this price point should not require multiple replacements in a single year, nor should customers have to argue for basic consumer protections. Based on my experience, I cannot recommend the Ultrahuman Air Ring due to poor durability and an unsatisfactory resolution process when things go wrong. I would also like to THANK Amazon for their levels of service.. they dealt with the refund in less than 2 minutes!!.. Stark contrast to Ultrahuman.. Thank you Amazon... Ian D

Fantastic piece of kit and sizing is bang on, quick to charge and lasts ages, sleep insight is so detailed

This is a fantastic product it tracks all my progress and is so comfortable to wear really pleased I choose this item

Had the ring about 10 months and generally disappointed. I don’t think it’s a good investment if you are sporty, far better to stick with a sports watch. It is really poor and registering movement. I have tried it alongside a Garmin watch for 3 months and undercounts steps by up to 40%. Really poor at picking up heart rate if you are exercising. Cycled earlier, hit 155bpm, ring recorded max of 135bpm I like the health stats on sleeping and stress, really detailed. Though ring randomly doesn’t record any sleep stats about 1-2 days a month. I bought because I didn’t want to wear sports watch all the time when I have other decent watches, and ring is unobtrusive. But I wouldn’t recommend if you are sporty like me, fine if you just want to record sleep/stress
