[This review was collected as part of a promotion.] I wrote this as my review: Love the app for the ring. I've gained good insights into what affects my sleep for better or worse. The insights from the ring are much, much more in depth than I initially thought before I bought the ring. I had learned that while my sleep was good, my "morning alertness" was a big cause of why I felt so tired, so I've made major changes to stop checking my phone first thing in the morning and get moving instead. I knocked off one star mostly for battery life -- wish it were better. Other than that, I've stopped wearing my fitness watch in favour of the ring for its small form factor and detailed tracking.

[This review was collected as part of a promotion.] I bought my ring 13 Month ago, and sadly the first versions I received had some problems. On the first one after 2 Month all sensors stopped working but Ring was still charged. On the second and the third ring the epoxy got weak after 4 Month and pieces of epoxy fell out where upon the ring either stopped working fully or took a day to charge and half an hour to discharge. The forth ring I received now 3 Month ago and sofar so good, Epoxy still normal, sensors work fine and battery all ok. All broken rings replaced under warranty without discussion. As for its functions, it is just great, I use it the most to track my sleep and heartrate, but also tracking sports is easy. What I like the most is that you do not notice wearing it, due to its weight, same or lighter then other "normal" rings.

[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.] My ring is comfortable and stylish - I've gotten a lot of compliments on it with people thinking that it is a fashion ring. It has provided very helpful insights for me from activity, sleep, to very accurate detection for menstrual cycle start. I would recommend to everyone.

[This review was collected as part of a promotion.] I bought this three months ago to track my steps and very happy so far. Step tracker is great and better than buying a watch. I find the battery is good and very easy to charge, lasts long and don't take to long to get to full charge. The sleep tracker is interesting with lots of information. There is a lot of information and I do find I skip over as some of it as I don't really understand it. The add ons are a nice touch and very interested what we will see in the future. As I said great step tracker, interesting for sleep, good for stress and like all add-ons

[This review was collected as part of a promotion.] I got my wife an Oura ring. She wanted me to have a smart ring too and I picked the Ultrahuman because I hoped it would help monitor for a-fib and also because I didn't need a monthly subscription. It seems to track sleep as well as the Oura and costs less, so that's a win. Unfortunately, the a-fib detection wasn't available in the US yet. The caffeine window feature is nice, reminding me when to stop drinking caffeine and to delay in the morning.

[This review was collected as part of a promotion.] I bought this ring in November and overall it’s fine, but I don’t think it’s super accurate. If I charge it overnight, it will still say that I slept and gave me a sleep score but I wasn’t wearing it. This has happened multiple times. It’s nice to wear and not bulky on uncomfy. Also I think the goals/metrics are mostly for walking, I don’t think it tracks other activity well. Also my charge will only last a day if I try and log any activity.

[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.] Really good product for general health tracking, but not really best fit for fitness tracking. The app is really good and I understand the limitation of a ring as a fitness tracker so I hope it integrate other source like other smart watch that track heart rate during the day through the app. As I said due the limitation of small battery and being a ring compare to other ring the app is amazing and subscription-free, honestly it is a good step and sleep tracking device not a replacement for a watch, more like an adds-on.

[This review was collected as part of a promotion.] I’ve been using it for three months now, and there are some things that I like and some things that I don’t I find that the heart rate tracking, especially when I’m logging a workout is very inaccurate. I’ve even compared it with results from another fitness tracker of mine that I’ve worn at the same time to confirm. The sleep tracker is probably my favorite feature.
