Great to see all the tips and tricks based in your statistics! These are very hands-on and almost immediately give higher scores. Only thing is I can’t seem to get the app working on iPad, it does work on iPhone for me. Is it possible to connect your ring to multiple devices?

[This review was collected as part of a promotion.] I am thrilled with my Ultrahuman Air ring. I purchased it and a leading competitor to do a side by side review. After just 2 weeks, I returned the other ring - the Ultrahuman was just so much better. The Ultrahuman app is amazing. Almost immediately I started seeing improvements in my sleep, health and energy level. Both my Ultrahuman app and my Apple Health app showed significant improvement in many areas (HRV, deep sleep, amount of sleep, Vo2, resting heart rate, etc.) in just a few weeks. I did a lot of research before buying. In the past several people have had problems with their ring not recording data. I have not had any problems. But one person said that when you are picking a size it's best to get a ring that is too tight to take off in the morning without using water. I did that and my ring stays in place during the night. If the ring is too loose it will twist around and not be able to record your info. Also, try to pick a size of ring that you can move to other fingers if you lose or gain weight. Finally, the ring is NOT as good in measuring workouts and your steps as the Apple watch. But I have a watch for that. From personal experience the ring is MUCH better at tracking sleep. It often shows more deep sleep than my watch. Also, it tracks the REM and other stages more accurately. Often I wake up suddenly during a dream. The ring shows that I have gone directly from REM to awake. The watch does not show that.

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.] Iv had my Ultrahuman ring air for a few months now and getting to grips with the various insights is making life a little easier. The few patters I have picked up on have allowed me to change habits to work towards a healthier life.

[This review was collected as part of a promotion.] I love i'm able to track my sleep, stress and recovery. Its so light i barely felt its there. It kinda replaces my smartwatch. I said kinda because there is still some features that i hope it has but it doesnt. Example the find my phone features, and i do hope that it has a better ability of recognizing when i'm doing a workout.

[This review was collected as part of a promotion.] I bought my Ultrahuman in Nov 2024 not having heard about the brand before. I was introduced the previous month to Oura ring by friends, but opted to buy Ultrahuman as it is just what I was looking for. It gives me pointers to have restful sleep (which is the reason I bought it in the first place) but I now find other features to be immensely useful. The ring is a versatile alternative to to bulky watches and I love the idea that my ring is constantly evolving with new features

[This review was collected as part of a promotion.] I am really enjoying my Ultrahuman ring! I love seeing my sleep score when I wake up and tracking my stats throughout the day. It has really helped my daily and sleep routine to become more productive. I really appreciate that Ultrahuman is always adding new features, insights, and small little changes that help the overall function of the ring. The only thing I wish was an option, was to sync my apple health data to my ring as well, instead of just syncing my ring data to my apple health as this sometimes leads to double counting of steps, etc.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for the past few weeks, and I can confidently say it's one of the most impressive health wearables I’ve ever tried. 💤 Sleep Tracking: Unmatched Accuracy The sleep insights are incredibly detailed — not just light/deep/REM stages, but also sleep efficiency, HRV, resting heart rate, and temperature deviation. I finally understood why I felt tired some mornings even after 8 hours of sleep. ❤️ HRV & Recovery Monitoring The Ring gives me daily Recovery Scores, factoring in my HRV, temperature, and sleep quality. This has helped me optimize my workouts, knowing when to push hard and when to rest. I’ve never felt more in tune with my body. 🔥 Movement & Metabolic Scores Ultrahuman doesn’t just track steps — it gives a holistic view of how much I’m moving and how it impacts my metabolism. Combined with smart nudges, I’ve naturally improved my daily habits without feeling pressured. 📱 Beautiful, Intuitive App The Ultrahuman app is beautifully designed, easy to navigate, and filled with actionable insights. I’ve used other platforms like Oura and Whoop, but Ultrahuman feels more modern, practical, and motivating. 🪶 Comfort & Battery The Ring AIR is super light, I forget I’m wearing it — even when sleeping or working out. Battery life easily lasts 4-5 days, and charging is fast and hassle-free. Ultrahuman Ring isn’t just another fitness tracker. It’s a real-time feedback loop for your body, health, and lifestyle. Whether you're an athlete, a biohacker, or just someone who wants to optimize energy, sleep, and stress, this ring is a no-brainer. Highly recommended. 10/10.

[This review was collected as part of a promotion.] I have had this ring about four months now and it has been the greatest! Charge last a couple of days and it is always giving me accurate information! It has been a game changer for my health issues with my doctors as well. I can share the information with them very easy!

[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.
