Love my ring!

[This review was collected as part of a promotion.] I bought this ring 2 months ago and it has given me so much knowledge into my body and it is so lightweight on the finger . The only thing is the battery life does not last as long as advertised. For me it’s about 4 days max, which I don’t mind.

Very good purchase

[This review was collected as part of a promotion.] My experience until now is quite good! It measures my sleep quality, my heart rate, and in some way also my physical health. Especially as a woman, the cycle tracking is quite good and its interesting, how my body temperature changes throughout the cycle. It also explaines, why the temperature is changing like that and also how your body may behave during your cycle. All in all, I have only good things to report!

Great ring but battery problems

[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!

Comfortable fit, predictable battery life

[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.

I love my ring!!

[This review was collected as part of a promotion.] I love my ring!! It’s so light and comfortable to wear. For the most part it provides very informative and accurate insights. One thing I’ve noticed is the step count is very off from my Apple Watch. I wear both realistically so I’m ok with that since it’s more accurate in other areas. Overall I love my ring and has made a huge difference in my sleeping habits! Definitely recommend the purchase.

Two Month Review

[This review was collected as part of a promotion.] I have had my Ultrahuman ring for 2 months now. I am impressed with the information especially the lack of deep sleep I am having. The heart rate and other sensor readings are nice to track. Overall pleased.

Love it!

[This review was collected as part of a promotion.] I bought this ring a few months ago and I have loved it! I was nervous with all the negative ratings talking about the battery but I have had no issues and when I keep my ring in “Chill Mode” it lasts about 5 days. It is very accurate in detecting sleep and they are always updating the ring and adding new features! I wish I could connect it to my Strava app but that is my only complaint.

3 months

[This review was collected as part of a promotion.] I'm more or less satisfied with the ring, but I'm bothered by the fact that the step count differs a lot compared to the watch I wear alongside the ring. I have the ring in black, and it wears off quickly, so it doesn't look as nice as it did at the beginning.

Awesome Tool for Marathon Training

[This review was collected as part of a promotion.] Absolutely thrilled with this purchase! Comfortable lightweight, and provides all the information I need to keep my marathon training on track. I really love the detailed cardio and sleep pattern information which makes it easy to make sure that I am not over training.

Game changer for the with heavy tattoo's

[This review was collected as part of a promotion.] I have tattoo's everywhere, head to toe. Smart watches such as garmin etc dont work due to the ink reflecting the sensor. This changed everything, I get all the insights I've been missing and helping to make better health and life choices.
