[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.] The rings sleeptracking is working really well and helped me a lot in structuring my day. From caffeine windows and managing my circadian rhythm, the ring has really helped me improve my sleep quality and sleep hygene a lot. Wouldn't want to miss it ever again.

[This review was collected as part of a promotion.] Able to reorient my routines based on various parameters in order to achieve max scores on all. This helps me getting the Ultra age and cardio age as closer as possible to my actual age. Trying hard to get those age numbers below the actual ones.

[This review was collected as part of a promotion.] I have had the ring since November 2024. The hardware seems solid! The app has improved over time, but I do feel like the data should give more actionable insights rather than being so broadly informative.

[This review was collected as part of a promotion.] I had miscarriage and wanted to track my period because I didn’t know when it was coming back after the surgery. One day, I saw the notification saying my period is coming soon. Surprisingly it came on the day! I was very pleased to have the ring!

[This review was collected as part of a promotion.] I got my ring about 2 months ago, and I can't believe how quickly it helped me adapt my lifestyle. From getting more sleep, to increasing steps and focusing on my heart health. Easily the best investment I've made in my health tracking journey. Although I do wish that kettlebells were a dedicated workout to be selected.

[This review was collected as part of a promotion.] This ring has truly helped me understand my health to the fullest. I originally purchased to track my sleep, and it has helped me get my health on track by understanding my heart rate, HRV, and stress. I've already set personal records by exercising more and lowering my stress levels and heart rate! The only reason why I took off one star is because the smart alarm in the app is a bit buggy. There have been multiple times the alarm didn't go off even though it was set for the correct date/time.

[This review was collected as part of a promotion.] Former Oura user and Whoop user and I have to say the Ultrahuman is my favorite. It's got more features, it's more comfortable to wear, it's fast to update, AND there's no subscription. I'm super happy with it so far.

[This review was collected as part of a promotion.] So glad I decided to invest in an Ultrahuman! I originally invested in it for its ability to seamlessly track my sleep without having to wear an uncomfortable watch to bed (that would also have to be charged at some point in a 24 hour window. Since then, I can honestly say that my ring has helped me recognize and transform habits from sleep to Vitamin D exposure to caffeine intake to morning rituals. Excited to see how Ultrahuman keeps evolving!
