[This review was collected as part of a promotion.] It's been a little over a month since I started using it but it still surprises me with scarily good insights it constantly provides during the day. I mainly bought it for sleep tracking but this thing is surprisingly good at fitness tracking as well. I specifically enjoy the recovery score. It made me much more cautious about my caffeine usage and screen time. Can't wait to see more benefits the more I keep using it!

[This review was collected as part of a promotion.] I picked this up mainly for sleep tracking (I don't like to sleep with my Apple Watch). I changed the setting to max statistics (which uses the most battery) and just charging it when I get ready for bed or hop in the shower is enough to keep it going. At first I wasn't sure how accurate the data was (the first few days with it the ring said I was asleep while I was watching TV), but after a few days the accuracy improved. Then the first day time I got a cold it asked me the next morning, if I was feeling sick because my temperature was elevated and I had a horrible night of sleep! I did wind up putting black electrical tape over most of the charging LED, that thing is bright enough to light up my entire room, even when the ring isn't connected to it. There's really no need for it to be illuminated when the ring isn't on it.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring for a couple of months now, and I genuinely think it's a brilliant alternative to smartwatches—especially if you're someone like me who prefers classic watches over digital ones. This little device has significantly improved my quality of life, drawing my attention to things I had never really considered before, like sleep quality and my personal favorite feature: the “caffeine window.” It’s surprising how much insight such a small ring can offer. I never thought it would have such an impact—not just on my awareness, but also on my daily habits. To be honest, I didn’t expect it, but the ring has even helped me lose weight in just 2–3 months. One small piece of advice: if you're considering buying one and plan to lose weight, get a size that's almost too small. I went with a comfortable fit at first, but after shedding some weight, the ring became a bit loose and now sometimes rotates on my finger, making it harder for the sensor to collect data consistently. Highly recommended—this is probably one of the smartest investments I’ve made in my health.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for a few months now, and I can confidently say it’s one of the best investments I’ve made for my health and wellness. What sets it apart is the accuracy and depth of insights. It doesn’t just count steps or measure sleep—it dives into HRV, body temperature, recovery, metabolic score, movement index, and more. The Ultrahuman app ties everything together beautifully, giving clear and actionable feedback rather than just raw data. Sleep tracking is incredibly detailed, helping me understand my sleep cycles and how well I’m truly recovering. I also love how it detects subtle physiological changes that indicate stress or strain—especially useful if you’re active or training regularly. Design-wise, it’s sleek, minimalist, and surprisingly comfortable—I forget I’m even wearing it. Battery life is solid too—I get around 5–6 days on a single charge. Most importantly, it’s not just a tracker—it feels like a wellness coach on your finger, encouraging better habits without being overwhelming. If you’re looking for a smart ring that goes beyond the basics and truly supports performance, recovery, and metabolic health, the Ultrahuman Ring is absolutely worth it.

[This review was collected as part of a promotion.] I bought this ring May 2025 and had the ring for about 3 months until the ring stopped holding battery. The battery would last less than 24 hours in the battery saving mode when it was supposed to last 4-6 days. When I contacted support about it they were very helpful and eventually sent me a completely new ring - hopefully this one lasts. Besides that I have really enjoyed the ring especially the circadian phase tracking. I use the ring as contraceptive so I hope they come out with more features to support that tracking!

[This review was collected as part of a promotion.] Love my ultrahuman ring! I’ve had it for a few months and wear it everyday! Only thing is I wish it would be better at taking treadmill steps in to account for overall steps! But otherwise I love being able to track my sleep and movement. The app makes it really easy to navigate

[This review was collected as part of a promotion.] I purchased this ring approx 4 months ago to track my steps and movement. However there are a few things I have noticed: When I am at the gym the ring does not pick up my heart beat as well as my myzone. Eg I am on the stair master and my hear rate is 115bpm. Maybe I picked the wrong size ring, but the smaller ring does not fit my finger. I have to clench my fist for the ring to pick up the heart beat. Also I need to type at work and some days my step count seems very high and I think it is because of the typing. Because of these issues I do wonder whether the other features such as sleep and dynamic recover is accurate. Would I purchase again? Probably. I do like the look of the ring and it feels good on my finger.

[This review was collected as part of a promotion.] I bought this a few months ago and I love it so far. It's much less bulky than other workout/sleep/lifestyle smart trackers and I feel that the insights are helpful in detecting where I can improve my sleep and exercise habits.

I bought my ring 3 months ago and the feature I use the most is tracking my sleep and temperature. Thanks to Ultraring I have better knowledge what affects my sleeping and I have been able to get much better night time rest. Feature that needs improving in my opinion is movement tracking.

[This review was collected as part of a promotion.] I never really had any interest in a tracking ring until my coworker mentioned her ring to me. She told me about how it showed her when to drink coffee and when to stop and did deep dives in your sleep stats. I looked up the website and found more cool features like cardio tracking and i'm totally stoked on the new blood panel testing they just released. The best part, no monthly subscriptions, unless you want and even so, they run low. I love my ring and tell everyone who will listen about it. Buy yourself an Ultrahuman ring, you won't regret it.
