[This review was collected as part of a promotion.] I love this ring! One of my favorite features is the caffeine window and the sleep tracking. I’ve always wondered when i should be tapering off caffeine and what time is best to start getting to bed. If you’re looking to better your health habits, you won’t be disappointed.

[This review was collected as part of a promotion.] The ring is stylish, very light and durable. After 10 or so months my black matte AIR has only a tiny scratch from when I did not take it off during weight training. I mostly use it for my sleep tracking, as for exercises I use a watch. I stopped drinking coffee in the morning because of its suggestions :) I would buy again.

[This review was collected as part of a promotion.] Initially everything worked wonderfully, then I noticed ongoing issues with the charge. It takes a significant amount of time to charge, then the battery drains very quickly. In addition, it has just not worked all day today and is prompting me to complete a factory reset, losing all my data. The dashboard is not showing anything or collecting any info. It often disconnects while I workout and will not let me end my workout session. At first the sleep features with the caffeine windows performed amazing and were game changers.

[This review was collected as part of a promotion.] I’ve been testing the Ultrahuman Ring Air, and it’s quickly becoming a valuable tool for monitoring recovery, sleep, and overall readiness. The design is sleek and comfortable, making it easy to wear around the clock without disrupting daily activity or training sessions. What stands out most is the depth of insight provided. HRV tracking, sleep stage analysis, and metabolic health markers are presented in a way that’s both actionable and easy to interpret. The seamless integration with Ultrahuman’s ecosystem adds another layer, allowing for a more holistic approach to athlete monitoring and personal performance optimization. For anyone serious about understanding their body’s response to stress, recovery, and training load, the Ultrahuman Ring Air offers a level of precision and usability that’s hard to match. I’m excited to continue exploring how this can support athletes at the elite level.

Ring is a good fit and able to give feedback that I need. I am using the ring mainly to track my sleep and steps. It is more convenient than a watch which can be bulky. It is also more comfortable to wear this to sleep since it is small. Data seems to be very close to my Garmin watch, so I believe that the data is relatively correct.

[This review was collected as part of a promotion.] The Ultrahuman Smart Ring has been an absolute game-changer for me. Its sleek design is incredibly comfortable for 24/7 wear, and I barely notice it's there. The data it provides on sleep, activity, and recovery is incredibly insightful and has helped me make tangible improvements to my health. I particularly love the detailed sleep analysis and how it helps me understand my readiness for the day. The battery life is impressive, lasting several days on a single charge.

[This review was collected as part of a promotion.] This was a great purchase! Thanks to the caffeine window feature, I stopped drinking coffee right after waking up and started feeling more energized during the day. It also motivates me to stay more active during the day, and offers many interesting insights into my health. I really like that they are rolling out new features all the time!

[This review was collected as part of a promotion.] After tons of research, I settled on the Ultrahuman Ring AIR, and I'm glad I did. The app is so very user friendly and I absolutely love how I can dial in which notifications I can receive. I compared the ring for the first few weeks with another watch-based tracker, and the results were identical. I absolutely love that it catches my activity level - even naps! - without me always having to enter data! Very accurate. And the ring is so comfortable to wear!

[This review was collected as part of a promotion.] I bought my ring 4 months ago and I have mixed feelings. I love how light and sleek it is. I get compliments on the look of it all the time. I prefer it over wearing a watch. I love the sleep insights and all the data it collects. However, my one con is that the battery life is terrible. It took a while for the ring to calibrate to a place where the battery lasted a few days on a full charge but now after 4 months post-purchase I had to get a replacement because the battery dies within hours after a full charge. For the price, I would hope the item would last way longer.
