Very attractive insights

[This review was collected as part of a promotion.] I really like the ring, it comes with several reports and great insights on cardiovascular status and brain health. The fertility/ovulation tracker is interesting and why I got this product, but I wish it could be developed further and become a central part of the app instead of just a plugin.
There's another plugin on caffeine consumption window, which is interesting but not necessarily accurate. For instance, I know I am a fast metabolizer, can drink coffee or energy drinks just before bed, but the ring is not capturing that. Otherwise I am looking forward to the updates!

Life-changing insights in a tiny ring

[This review was collected as part of a promotion.] Since getting the Ultrahuman Ring AIR for my birthday, my sleep and overall well-being have improved dramatically. The caffeine tracking helped me cut back at the right times, which led to deeper, more restful sleep. Real-time stress and pulse monitoring have made me more aware of my mental health and helped me build better habits. I feel more balanced, focused, and in control. Exactly what I needed.

Eh

[This review was collected as part of a promotion.] I’ve been wearing my Ultrahuman ring for about two months now, and it’s ok. I don’t get very accurate heart rate data when working out. I tend to wear my Apple Watch for workouts, spin class and walks or runs which defeated the purpose of my purchase. It is comfortable and I like the look of it.
No, I would not recommend this to a friend.

Great, but….

[This review was collected as part of a promotion.] Ultrahuman Ring is great. It nicely complements my portfolio of smartwatches with other useful data. It is nicely made, has good battery life and is comfortable to wear.
As a tester of smart devices, however, one thing is not going through my head. The HRV value. Although it is within the norm according to the application, it absolutely does not correspond to the values from my watch. And I am testing two models at once, where the HRV almost matches, while the ring shows completely different values. So somehow I can't figure out what algorithm it works on. The same goes for the accuracy of the heart rate sensor, which also needs to be fine-tuned.
There is also a small but unpleasant error in the translation of the application. As a Czech, I prefer the Czech language, and the translation is very basic, so some translations in the final do not make much sense. Otherwise, I am satisfied with the product.

[This review was collected as part of a promotion.] I’m absolutely impressed with this smart ring! It’s sleek, lightweight, and incredibly comfortable to wear all day. The tracking accuracy for sleep, heart rate, and activity is spot-on, and the battery life is excellent. I love how discreet it looks while still giving me valuable health insights. Syncing with the app is smooth and user-friendly. Totally worth the investment – highly recommend it for anyone who wants smart features in a stylish form!
