I bought this a while back, and at first, it worked well. However, I realized the battery doesn't actually last the whole week, just 3-4 days maximum, and I charge it overnight. The ring also randomly disconnects or says there is not enough data to give me my sleep records, for example, which is weird when I know for a fact I slept 6 hours.

[This review was collected as part of a promotion.] Everything is good. In 80% of cases, the results match my overall well-being. The metrics are very informative. I would like to see more gamification to help users reach their goals, as well as specific recommendations on what to do to improve the results.

[This review was collected as part of a promotion.] I bought this ring when I was looking for a smart ring to detect my activity especially my sleep and also my fitness. From some brands, I totally like this ultrahuman. Battery life is not the best but still enough to last for minimum 5 days. A bit expensive though but compared to the accuracy data it gives, it still worth it.

I have been using this and comparing with readings from my apple watch. They don't always agree and I can't be certain which is more accurate. I have found that the Ultra Age and the Cardio Age fluctuate quite a bit and are never really in agreement with each other. I do like using the ring to track heart rate during workouts. But, other than that, I haven't been able to use it for much else.

[This review was collected as part of a promotion.] I bought this ring 2 months ago and had issues the first weeks as its sleep readings differed greatly from my fitbit- which I also wear to sleep. After several weeks tho, the difference between the 2 wearables are not that big so I guess it has calibrated tho there are still days that it seems off.

[This review was collected as part of a promotion.] I have had my ring for 3 months so I feel like I’ve had plenty of time to really utilize its features. I love the sleep data and feedback. I have actually been able to make positive changes to improve my sleep behaviors. I’m also very motivated by my step tracking, and heart health results to move more! Overall, I’m very happy with this investment in my health.

[This review was collected as part of a promotion.] The product performs very well with regards both the tracking of the health data and also the battery lasts around 4 days with full scale continuous monitoring. Easiest how to take care of the battery is to charge during the dinner or when going to shower. The shiny version

[This review was collected as part of a promotion.] I bought the Ultrahuman Ring 3 months back. Overall its an excellant device supported by an app which gives a wealth of data and analytics. While comparing with my Garmin watch, i think the Ring shows lower count for steps and deep sleep. Need someone to analyse this. The app connects with Garmin Connect however the analytics of the activities should be correlated with the ring data. I havent found any literature about it

[This review was collected as part of a promotion.] I bought my ring a couple of months ago, based on personal recommendations and reading reviews. I tested the template rings first, which is a great idea to ensure you pick the correct size and also the colour you prefer. Set up is simple and I was able to use it straight away. I’ve found that the step count numbers vary quite a lot from both my Apple Health and Fitbit phone tracking apps and also my Garmin watch. The counts are significantly lower than all the others. This may be because it is more accurate but it was very surprising, given the others were all at similar levels. I don’t find some of the app metrics overly useful as yet, and feel like the sleep score could be part of the overall dynamic recovery measures. The jet lag measure just displays the same info most of the time too. The caffeine metric is one I have been using a lot and find value in this one, which is good. Also not having to pay a subscription is a big benefit. Overall, I’m glad I’ve tried it but do think there is room to improve on a number of factors, to take it to the next level.

[This review was collected as part of a promotion.] Thoroughly enjoying this fitness tracker! I've mad my ring for 2 months now and it is one thing that I rarely take off. I purchased it out of interest and wanting better sleep insights as I struggle with sleep consistency. Let me tell you, I got much more than I was expecting. The insights providing are amazing! There's so much information that I have yet to learn to interpret all of my daily/weekly insights fully. As a woman, I was interested in the cycle tracking and those have been interesting. I have noticed that the insights do change based on the data received and input on the app - which I appreciate.
