[This review was collected as part of a promotion.] I love the battery life, it lasts at least five days, so it is always monitoring my sleep. I wanted a ring without a subscription, so this ring is great. I find the app confusing and hard to make sense of which makes me curious to try a different brand.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for a while now, and overall - it’s pretty solid, especially when it comes to sleep tracking. It actually helped me become more aware of my sleep habits, and over time I started making better choices because of it. So yeah, it’s great if you’re trying to improve your recovery or just want to feel more in control of your daily rhythm. The ring also tracks HRV and VO2 max, which is cool – but honestly, I’m still not 100% sure how it calculates those numbers. The data looks impressive, but it’d be nice to understand exactly where it’s coming from. Now the not-so-great part: training tracking. If you’re expecting super accurate heart rate during workouts, you might be a bit disappointed. It’s okay for general trends, but it’s not super precise yet - especially if you’re doing intense or fast-paced workouts. Hopefully they improve this with updates. Bottom line? It’s awesome for sleep and recovery. Still a work in progress for workouts.

[This review was collected as part of a promotion.] Received as a gift, purchased the extended warranty and cannot use warranty because I do not have a receipt or purchase info. Very disappointing because I was loving my ring, but now must abandon my ring (note: support will not authorize replacement without purchase info) plus dispute the money I paid for extended warranty. Spent hours on chat trying to resolve this, and I'm so aggravated by the process its impossible to leave a positive review.

[This review was collected as part of a promotion.] I love the ring experience and the changes in lifestyle it triggers if you engage in this journey. I definitely changed my behavioural patterns for the better, and I like the sleek jewelry look that I can (and do) wear with any outfit. Unfortunately I’ve had quite some battery issues after a few months, but these are being taken care of.

[This review was collected as part of a promotion.] Overall, I am really enjoying my Ring AIR. It’s pretty accurate and I enjoy all of the features and ‘power plugs’ that are available. I love that you don’t have to pay a monthly fee for the app, that’s why I chose this option instead of the Oura. I have had some problems with the ring tracking and syncing both my sleep and activity at times, which is a little frustrating. I’ve contacted support through the app and each time they’ve been helpful! I’m happy with my purchase and would recommend!

[This review was collected as part of a promotion.] I bought this a month ago. I'm happy with some things but disappointed with the workout data received. I gave up my smartwatch and bought this ring. But, there has been major glitches in data accuracy. I worked out for 60 mins and it showed 54 calories burnt. I mean how strange is that?

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for several weeks now, and I can confidently say it’s become an essential part of my health and fitness routine. What sets it apart for me is how seamlessly it tracks sleep, recovery, and overall readiness without being bulky or intrusive. I wear it 24/7, and often forget it’s even there. Sleep tracking has been especially impressive. The insights into my deep sleep, REM cycles, and HRV have helped me make meaningful changes to my bedtime routine. I’ve noticed that on nights where I prioritize wind-down, my ring reflects the quality improvement—and I feel it too. The daily recovery score is one of my favorite features. It helps me decide whether to push hard in the gym or take a lighter day. It’s like having a coach who reminds me to listen to my body without the guesswork. I’ve noticed better energy levels and fewer slumps since I started using the ring to guide my training intensity.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for the past few weeks, and it’s really shifted how I look at recovery and staying focused. I’ve started noticing patterns in how I sleep and move through the day, and it’s helped me make a few small changes that actually stick. The recovery score, in particular, makes a lot of sense to me—I find myself checking it before I even start the day. Kind of wild how something this small can be so useful.

[This review was collected as part of a promotion.] I bought my ring in June and I’ve been primarily using it to track my sleep! I find it gives very accurate readings and is really good at giving me suggestions and graphing my data. The only reason I gave it four instead of five is that the ring scratches super easily. I have the gold and a lot of it is basically silver at this point. I don’t wear rings around it at all so it’s not rubbing on anything. The battery is okay, I charge it probably every 3 to 4 days. I was hopeful it was going to last longer. Also, often when I go into the app, it takes quite a while to load my data and I have to refresh it quite a few times.

[This review was collected as part of a promotion.] The experience has been great so far. I have been tracking my fitness and recovery scores regularly from the ring, and it's helped me plan my routines much better. I have been working out for quite some time now, and I am always trying to figure out ways to optimize what I can get out of my lifestyle. We all know that sleep and recovery is a huge part of living a fit life, and somehow that has been consistently lacking from my routine. Bought this ring to be more mindful around my sleep and recovery, and honestly haven't been disappointed
