[This review was collected as part of a promotion.] I have been using the ring for about a year now and I am very satisfied. I track my sleep cycles every day, I follow the caffeine window, I use it a lot when exercising. All the results are very clearly interpreted, I use several powerplugs. I would definitely buy it again.

[This review was collected as part of a promotion.] Basically, I've replaced my smartwatch with the Ultrahuman ring. I only use the watch now during workouts when I want a timer / screen to track my workout, as I'm not interested in notifications and such pestering me and only used the watch for health features. Everything I need can be done by the ring, and some of those are done much better than any watch I've used in the past. For example, the sleep tracking is really good, with great detection of begin and end. I also like how it feels like the ring is actually actively maintained, with features coming out every now and then.

[This review was collected as part of a promotion.] I was sleeping 7–8 hours most nights, but waking up feeling like I hadn’t slept at all. I’d scroll through sleep tips online, try magnesium, meditation, no screens before bed—you name it. Nothing really stuck, because I didn’t know what was actually going wrong. This ring changed that. It didn’t magically fix my sleep overnight, but it finally gave me a way to see what’s happening while I’m asleep. Turns out I wasn’t getting enough deep sleep, and my recovery scores were way off after high-stress days, even if I hadn’t worked out. The HRV data, resting heart rate, even skin temperature started to paint a fuller picture of what my body was going through. I also started noticing how my sleep improved when I ate earlier, skipped alcohol, or took a proper wind-down routine seriously. Before, it all felt like guessing. Now it feels like learning. The ring itself is great—super light, looks good, and I barely feel it at night, which is huge. I didn’t want another thing buzzing on my wrist. Honestly, I bought this ring because I was tired of being tired lol. But it makes a huge difference in my life.

[This review was collected as part of a promotion.] It is good but I think it would benefit on having AI that one could ask concrete questions about your performance and it can provide you advice based on what it has measured you. Also battery is not the best one

[This review was collected as part of a promotion.] DON'T BUY IT! I bought my ring in the spring and already will not hold a charge longer than 7 hours. I have done multiple resets on the ring, checked all settings to ensure other apps are not draining the battery and still will not hold a charge. Since it will not hold a charge longer than the 7 hours, i cannot even use it to gather data on my sleep, limited thru the day as well and have to charge it just to even track steps. Buy the Oura!

[This review was collected as part of a promotion.] Overall happy with the ring. More of a health tracker versus fitness tracker. It doesn't seem to pick up exercise automatically and if I indicate I'm exercising it often loses connection with the HR seeming very off or inconsistent. I enjoy the sleep and stress tracker. Over the past month, the battery has drained very fast. After charging it'll tell me to charge again 4-5 hours later. I reset the ring and updated the software without improvement.

[This review was collected as part of a promotion.] I've been using the ring for over half an year now and Im super happy with it. The activity tracking for sports could be better but since I tend to use a sekretem device for this im not too bothered. Sleep tracking is excellent but I think cycle tracking was the biggest game charger for me. I never rememberd to track my cycle and now that ist done pretty much automatically I've started connecting my symptoms to my cycle and discovered my healh issues are due to perimenopause. The data collected made it so much easier to advocate for myself with my health provider! No subscription is also key here!

[This review was collected as part of a promotion.] Valuable data points are being collected. Hardware design is very minimalist and can easily blend with other jewelry. Battery can be prolonged in the future but the chill mode has immensely helped with battery life. Just because I have garmin 965 as my daily driver I sometimes forget to charge my ring after 2-3 days which I never do with my garmin watch.

[This review was collected as part of a promotion.] Overall, I like this product a lot. There are a lot of cool features, data to analyze, and they display it for you in a way that is digestible and not overwhelming. I like the suggestions it gives you based off of different patterns you have. The best thing I like it for is the sleep analysis, and the score it gives me. It gives me insights I haven't had before! Although now that it is a year out from me having it, I did start having some performance issues like it not tracking data completely.

[This review was collected as part of a promotion.] I use Ultrahuman ring everyday and most of the data points are reallyuseful, sleep cycle info in particular. However, their activity tracking still needs inprovement i.e. it records steps when I'm riding a motobike and does not pick up other activity like pilates even when I upload them manually. Really hopethis will be corrected with further software updates
