[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring for a while now and have truly enjoyed the product. The overall experience has made me feel that health should be approached through the Ultrahuman Ring and their app. I like the caffeine window.

[This review was collected as part of a promotion.] I bought it a few months ago. It works mostly like expected but I have some issues. When working out it takes forever to connect when starting the work out and ending it. During the night the app sometimes doesn’t work through the night and my alarm doesn’t go off. However, the menstrual cycle prediction is very good.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring for a few months now, and I can confidently say it's one of the best health and wellness devices I've ever owned. What truly stands out for me is the incredible sleep tracking. The insights it provides are not only detailed but also actionable. I can now understand how different habits affect my deep sleep, REM cycles, and overall recovery. The best part? The ring is so comfortable, I forget it’s even there. It’s on my finger 24/7—through workouts, showers, and while I sleep—and it never feels intrusive. The continuous monitoring gives me a full picture of my health, but sleep tracking is where it really shines. The app is intuitive, and I love how it breaks down complex sleep metrics in a simple, visual way. I’ve genuinely improved my bedtime routine and energy levels thanks to the guidance it provides. If you're serious about improving your sleep and overall well-being, I can't recommend the Ultrahuman Ring enough.

[This review was collected as part of a promotion.] Have had the ring for 1 year now and has been great. Build quality is good, no physical issues. Consistent updates have improved functionality. Some updated caused issues with battery life but subsequent updates have corrected any problems. I have a smart watch and the data between the 2 devices is very similar, with the ring providing a what I feel is more accurate sleep data than the watch.

[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.] I have purchased my ring ca. 3 months ago and using it ever since. What I like: - sleep tracking - caffeine window - workout tracking - workout tracking - new parent function :) - the UI has a nice appeal - no subscription What I would change: - bad connectivity with ring-phone - long updating times between ring and phone (updated app, reseted phone, meanwhile changed to new phone) - every time ring update is available I have to reset the whole ring since it remains stuck updating The overall appeal of the ring is positive with some throwbacks, mostly SW related. If new ring will be available on the market, I highly consider upgrading :)

[This review was collected as part of a promotion.] I bought my ring at Christmas and it is now July. I love how it tracks everything and provides detailed information! Stays charged for a few days at a time. I recommend charging when you take a shower/get ready for the day! The only reason I didn’t give it 5 stars is because it is scratched up and the gold coating is wearing off even though I use a silicone cover while working out.

[This review was collected as part of a promotion.] I’m a middle‑aged woman who started at around 200 lbs, and the Ultrahuman Ring AIR has been a real game changer in my weight loss journey. It’s lightweight and comfortable - you barely feel it - and it gives clear, subscription‑free insights into my sleep, recovery, and daily activity. Seeing how well I slept and recovered each night helped me adjust my evening habits and push just the right amount during workouts, which made losing those first pounds feel manageable and sustainable. The ring lasts several days on its battery, the app is clean and easy to use, and it really felt like having a wellness coach on my finger.

[This review was collected as part of a promotion.] I am completely satisfied with my Ultrahuman Air ring. I bought it a few months ago and I can already feel a noticeable shift in many things. My sleep has improved. I know when to rest more and when to exercise more. It has also improved my caffeine intake, which has had an effect on my sleep. Great piece of hardware!

[This review was collected as part of a promotion.] I’ve been using it for three months now, and there are some things that I like and some things that I don’t I find that the heart rate tracking, especially when I’m logging a workout is very inaccurate. I’ve even compared it with results from another fitness tracker of mine that I’ve worn at the same time to confirm. The sleep tracker is probably my favorite feature.
