[This review was collected as part of a promotion.] I bought the ring 3 months ago after comparing it to several other 'smart rings' and I am so glad I chose this one. Mainly I use it to track my steps and heart rate as well as sleep. The app has a ton of features and is easy to learn to use.

[This review was collected as part of a promotion.] I have had this ring for four months now and it has been fantastic. The insights you get when you are tired, not sleeping good, or even not feeling well. This ring helps you understand why you may feel the way you do and gives you hints and tips on how to combat it and do/feel better.

[This review was collected as part of a promotion.] The Ultrahuman Ring has been an amazing tool. It's helping me understand how to optimize my sleep with precise measurements and recommendations. The information provided is actionable, which is something not found with wearables I've tried in the past. It's helping me build better eating and sleeping habits and I strive to get 90s when I can. The ultra human age is something I've been working to improve and also a feature I haven't seen on my wife's Oura ring. It's been great to see my brain age get younger with better sleep habits. The additional features such as breath work have been fun to use when I do my red light/IR therapy sessions. It's become my constant companion and I have only ever taken it off for charging (the battery life is outstanding). The alarm clock that syncs with my sleep cycles is also a neat feature. Overall, very happy with my purchase. At first thought I was making a mistake of owning both an Apple Watch and the ring, but they each have their uses!

[This review was collected as part of a promotion.] I absolutely love my ring!! Getting such an in-depth look at my daily metrics and what affects my sleep has really helped me prioritize better habits and make sleep more important to me. It’s very accurate, super easy to use, and I have had literally zero technical issues. Love this ring so much!!!

[This review was collected as part of a promotion.] It’s been 8 months that I’ve been using the ring and feels like with every passing day, my actions are converting into stronger signals. Signals that I can trust, signals that keep me informed about my inner self. So intuitive and so essential.

[This review was collected as part of a promotion.] I got this as a gift in May and it has changed the way I view how much sleep I’m getting each night, it tells me when it’s detecting I’m getting sick. It’s really opened up a lot for me to see how my body is working throughout the day and night.

[This review was collected as part of a promotion.] I love the ultrahuman AIR ring! I hate having screens around me so a smart watch was out of the question. After a lot of research I settled on the AIR ring because there is no monthly subscription. I love all of the insight this piece of technology gives me! Sleep, heartrate, and cycle tracking! It has even predicted when im getting sick. The only reason this is not a five star review is because the battery life is not what is advertised. If you want it to last longer than a few days you have to sacrifice tracking.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring Air for the past few weeks, and it has quickly become an essential part of my daily routine. This sleek, lightweight wearable packs a serious punch when it comes to health tracking, offering a perfect blend of performance insights, recovery metrics, and personalized recommendations. Design & Comfort: First off, the design is stunning — minimalistic, elegant, and discreet. Unlike bulkier smartwatches, the Ring Air feels virtually weightless and looks great with any outfit. I often forget I’m even wearing it, which is a testament to its comfort. Metrics & Accuracy: The data accuracy has been impressive. From HRV and sleep cycles to movement and skin temperature, the insights feel both comprehensive and reliable. The sleep tracking is especially detailed, helping me pinpoint areas to improve my rest and recovery. App Experience: The Ultrahuman app is intuitive and thoughtfully designed. It doesn’t just throw numbers at you; it contextualizes them with actionable suggestions and clear visualizations. I particularly like how it integrates metabolic and circadian insights to help optimize performance and recovery. Battery Life: The battery life is stellar — I’ve been getting 5–6 days on a single charge, and the charging case is compact and easy to carry. Conclusion: If you're serious about your health, sleep, and performance, the Ultrahuman Ring Air is absolutely worth the investment. It's not just a fitness tracker — it’s a powerful tool for anyone looking to live smarter and optimize their everyday well-being. Highly recommended!

[This review was collected as part of a promotion.] I got it in March and already have the second replacement because it stopped connecting after a firmware update, so now I don’t update the firmware because I’m scared it will stop connecting again. But I am super happy with it when it is working

[This review was collected as part of a promotion.] Bought the Ring AIR about five months ago, mainly because of the no-subscription business model, and the other reason was for sleep tracking. It has been amazing to see trends over time, and the ability to easily access all the data as a csv file has been really helpful. Only a few days ago I decided to improve my sleep with supplements, and after four days of taking two of them (magnesium glycinate and L-theonine) I've seen measurable improvement. Having data regarding sleep stages, sleep time and other metrics like HRV and temperature drop has been super-helpful. I wear the ring all the time, and am happy to start tracking my workouts now as well. Highly recommended!
