[This review was collected as part of a promotion.] Comfortable, and packed with meaningful insights. Sleep and recovery tracking is spot on, and the app connects the dots between body and lifestyle in a smart way. Feeling great to track my health and sleep

[This review was collected as part of a promotion.] Very happy with my Ultrahuman ring, i can’t use a watch because it hurts my wrists, so the ring was perfect for me! I like how it looks and feels. Only problem I have is that the ring disconnect when i am running and have Headphones connected at the same time as the ring, so i don’t get step count or pulse readings on that workout.

[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.] 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.] Basically, I've replaced my smartwatch with the Ultrahuman ring. I only use the watch now during workouts when I want a timer / screen to track my workout, as I'm not interested in notifications and such pestering me and only used the watch for health features. Everything I need can be done by the ring, and some of those are done much better than any watch I've used in the past. For example, the sleep tracking is really good, with great detection of begin and end. I also like how it feels like the ring is actually actively maintained, with features coming out every now and then.

[This review was collected as part of a promotion.] The ring works well and detects things really well, except for the menstrual cycle even though I've been wearing it all the time since December, it still doesn't give the right predictions. And when will the weight loss module be available?

[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 bought this ring a couple of months ago and it’s super comfy to wear and feels more accurate than my old smart watch as im able to wear for longer stretches of time. The data is really insightful and the app is really easy to use

I’ve been wearing this for about 2 months now and I really enjoy the sleep score and period tracker! It does a really good job paired with my watch and it’s perfect for when I want to disconnect and just have the ring on. I like that it’s light and discrete. Most people just think I’m wearing jewelry until I tell them about it!

[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.
