I bought this in March I believe, and I really enjoyed it at first, but once I got an idea of what my results were going to be, I ended up not checking them any more. I don’t find the battery lasts that long, maybe a day and half to two days. I do get compliments on the way it looks, but as for a smart ring, I tend to lean more towards using my smart watch.

[This review was collected as part of a promotion.] At first the battery life was a bit dissapointing. Latest update made it really great. I feel like it's continous developing which I love. I had problems with two rings in a row, but got replacement and good support. The third ring now works great.

Love the detailed tracking and interpreted insights which the Ultrahuman Ring gives. It's not just raw data, but the insights derived from it that make all the difference. The build quality is top notch - I've never had to worry about scratching it (matte black variant).

I bought my Ultra Human ring in April, and while I love all the insights and the look of it. I have two issues with is, the first is how easily it scratches. I always wear a silicone cover over it while lifting weights but even during everyday it gets more scratched each day. And second is the battery life, its advertised to last for 4-6 days but really it only lasts for 3 days. I have tried chill mode but still the advertisement does not align with its battery capabilities.

[This review was collected as part of a promotion.] The battery needs to be charged more often than expected unless I turn it down to only track the minimal (sleep etc). Maybe it being in the sauna drains the battery or when I used to click a functional workout real time maybe that is also draining the battery. Lastly, I have the silver, and there are lots of hairline scratches on it and it feels like plastic on top. Maybe there can be other cooler finishes like textured to help disguise the scratch potential? Otherwise cool and lots of info and options.

The Ultrahuman Ring is a game-changer, and I'm hooked! Easy to use, accurate, and stylish - what more could you ask for?"

[This review was collected as part of a promotion.] I had higher expectations for this product. I’m now questioning whether I should have gone with the Oura Ring instead. The battery life barely lasts four days—even with Chill Mode enabled—which means I’m not benefiting from the full feature set. The ring itself scratched easily, despite careful, everyday use. I never lifted weights or subjected it to any harsh conditions. When diving deeper into the data, the insights and recommendations feel overly generic, making me question the accuracy and value of the data being collected. As someone training for an Ironman triathlon, I rely on precise, data-driven feedback. I purchased this ring with the expectation that it would account for my intense workouts. Unfortunately, it doesn’t. For example, after a high-intensity training session, there’s little to no reflection of that effort in the following day’s metrics. This lack of context makes the overall tracking feel basic and out of sync with real-world performance.

[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 bought my ring a month ago due to some health concerns and it gave me great insight into why I might’ve been feeling tired and struggled with migraines. I love being able to understand my body better.

[This review was collected as part of a promotion.] I bought this ring in November and overall it’s fine, but I don’t think it’s super accurate. If I charge it overnight, it will still say that I slept and gave me a sleep score but I wasn’t wearing it. This has happened multiple times. It’s nice to wear and not bulky on uncomfy. Also I think the goals/metrics are mostly for walking, I don’t think it tracks other activity well. Also my charge will only last a day if I try and log any activity.
