"In the first few days of wearing the ring, I was surprised that the sleep tracking results almost exactly matched my AWU. Even after six nights, this consistency continued. It seems I can stop wearing the watch for sleep tracking. ... Over the past couple of weeks, its sleep and wake time detection has closely matched my Apple Watch."
"It is a competent 24/7 health monitoring device ... the fact that the UH app provides not only numbers but also recommendations is excellent."
"Regarding sleep debt, unlike other apps that typically advise seven and a half or eight and a half hours of sleep, UH app suggested six and a half hours after a week of observation, which matches my usual experience."

"For me, my workouts have a pretty clear impact on the data and I think the insights are great. Like, if I did interval training today, my HRV will definitely tank tomorrow, and the UH app would tell me that it’s normal post-workout stress that helps the body grow."
"In my week of use, I found that if I train when the score is below 70 after work, I’m generally fatigued. When it’s above 75, I’m in a good state for interval training and similar workouts."

"This was one of the features I most wanted before purchasing. ... In the first three days of wearing the ring, when I wasn’t sleeping well, my caffeine intake window was very short, reflecting poor brain waste clearance and recommending an earlier caffeine cut-off. Over the weekend, after better sleep, the allowable caffeine window extended—it even told me I could consume caffeine until 4 PM. Clearly, the app is calculating dynamically rather than applying a fixed caffeine metabolism rate."

"Battery has been phenomenal imo. ... Right now it’s set to turbo mode, and no complaints."
"The smart alarm works well and hasn’t caused excessive battery drain."
"Battery life was a major concern before purchase. Fortunately, I haven’t encountered issues yet. ... It seems that the battery could last about 5 to 5.5 days per charge, which is acceptable for now"

"Ultrahuman is garbage btw ... I ran through 3 rings in under a year."
"had nothing but issues ... the majority of users have reliability and connectivity issues ... threw the ring away ... something that won’t work half the time anyway"
"On day 19, I encountered a Bluetooth connection issue. Customer service advised me to fully drain the battery to trigger a hardware reset, then recharge and reconnect the ring. ... Unfortunately, I had just fully charged it yesterday, so I’ll need to wait three to four days."

"However, the calorie count for activity is odd. On days I go for a jog, the calories burned are unusually high. ... For example: Static energy + dynamic energy = approx. 1,950 kcal A 10 km Zone 2 jog ≈ 700 kcal Total ≈ 2,650 kcal But the UH app always reports around 3,350 kcal—it’s clearly doubling the exercise calories. ... This issue matters to me: if I follow this inflated calorie estimate for food intake, I could easily regain the weight I lost 20 years ago."
"the Ring should improve on the sensors so that the accuracy of the data improves. ... I use my ring with my Garmin, and I usually trust my Garmin's data more as it correlates to how I am feeling more often than not."
"None of them are particularly accurate"

"UltraHuman sets impossible goals and activity metrics that do not move on a sliding scale."
"it was uncomfortable during the night and in the gym."

00ATom00 1.0I have been using UH for more than a year now and I align with all the reviews posted. If you want to read about the positive things you can look up their subreddit
Sleep tracking is okay-ish. Activity and workout tracking is very off. The best thing about them is their mobile app I'd say
AntiAd-er 1.0I use an Ultrahuman RIng Air to collect sleep and some exercise data. Full scale exercise data comes from Apple Health, GPX Tracker, and Withings apps. All these integrate into Apple Health for which there is a published API or it is possible to output a complete data dump from Apple Health. The native Apple Health data originates from either/both of my iPhone or Apple Watch. Unfortunately the Ultrahuman app is not fully integrated into Apple Health. Some of the data items never get carried across, for exampe, VO2max collected by the Ring does not appear in Apple Health. I have bitched about that in the Ultrahuman subreddit several times and will continue to do so but there has, as now, been no progress in a fuller/complete integration between the two apps. The Withings App on the otherhand seems to have bi-directionala integration with Apple Health.
as10085 1.0Also same problem at work I use a Fitbit and ended up getting a health tracker ring - love it just use the Fitbit as a digital watch and alarm now
I got the Ultrahuman one but they don’t sell them in the US at the moment some sort of lawsuit with oura effective in October. You might be able to find some residual stock at Walmart or best buy I got mine from Best Buy
Born_Bicycle316 1.0I also wear an Apple Watch Ultra 2 and I wouldn’t say a smart ring adds very much over what the AWU already provides, in terms of data. It’s more about how it aggregates and displays the data that’s more helpful. I really wanted to get better about tracking my sleep and wearing my giant Ultra watch to bed wasn’t comfortable so I decided to get a smart ring. I got the UltraHuman ring which is priced similarly to Oura 4 but with no subscription and I can tell you I wore it for 2 months and had nothing but issues. Looking deeper into Reddit, I found I was not alone by any means, in fact, it seems that the majority of users have reliability and connectivity issues. I finally had enough and threw the ring away and got an Oura 4 and it’s so much better, not only in terms of reliability / build quality, but in how it displays data and sets goals based on your data. I can’t speak for RingConn but UltraHuman sets impossible goals and activity metrics that do not move on a sliding scale. As an example, I slept poorly the other night and Oura recognized my recovery was low and lowered my activity goal to align with what’s realistic when you’re overtired and you didn’t have time to recover. It’s encouraging that even on bad days, goals can be reached by making them realistic. I’d much rather pay a subscription for something that works well than try to save $70 a year by getting something that won’t work half the time anyway. Buy nice or buy twice (like I did). Worth noting is both UltraHuman and RingConn were just banned from selling their rings in the US after October 21st in an ITC ruling that found they had infringed on Oura’s patent.
bumbleboyie 1.0Ultrahuman has everything except good battery. Samsung has nothing except decent battery. That said, the new ultrahuman ring pro is about to come out. 14 days of battery life if I remember correctly! You might as well wait a bit for that one.
dan360dan 1.0Check out Hume Band from Hume Health. I purchased a Hume Body Pod (smart scale) and am very happy with it. After getting the scale, they are now pitching me on the Hume Band. Looks like a Whoop clone. First, Hume BodyPod scale is excellent. Looks, build quality, the app is clear and well designed. I really like it after 2 months. FYI - I wore Whoop for 2 years and now have an Ultrahuman ring for 1.5 years. Reason to move to the Hume Band is that it will integrate with same app as the BodyPod. Haven’t done it yet.
davidesquadrone 1.0I tried the Ultrahuman ring for a few weeks but it was uncomfortable during the night and in the gym. At the end I tried whoop and I'm still using it. It's not bad, more precise than I expected.
firefly-of-saturn 1.0Tried both UH and Ringconn simultaneously with Oura, got rid of both and keep Oura. Both have good data etc, but it's also a matter of personal preference about the app, imho - I like Oura UI the best, even after redesign. UH was my close second and I like certain features like the ability to upload 3rd party blood work. Ringconn was my personal 3rd place. If the money allow, I would recommend trying all three to see whichever works best for you personally.
Fit_Clue_832 1.0I tried the ultrahuman ring and the garman and went back to fitbit.
Glad_Position3592 1.0I had the ultrahuman for 2 years (until the warranty expired) and had to get a total of 6 replacements during that time. It was absolutely infuriating, and I never had one that lasted longer than 6 months. I once had one need to get replaced after only 2 weeks. My Oura has outlasted any ultrahuman ring I’ve had at this point
