[This review was collected as part of a promotion.] I've had the ring since February 2024 and have loved it since day one. My main goal was to track and improve my sleep — and I’ve managed to do both. The missing star is due to occasional issues with the app not syncing properly with my fitness tracker (Strava). I usually don’t wear any ring during workouts (rowing, training, etc.), which sometimes causes the ring to misinterpret the lack of activity.

I’ve had my ring for a month now and it’s dramatically improved my sleep and recovery. The caffeine window is a helpful feature and the movement score makes me more likely to get extra steps in. I’ve found the ring great for tracking runs and your zone training but the only con so far is that I have to remove the ring when I am at the gym so it doesn’t scratch.

[This review was collected as part of a promotion.] Love the ring :) I was initially hesitant to buy it since I assumed it would not be as accurate as a watch for Sleep and Activity tracking. Ultrahuman Ring AIR proved me wrong, and I'm glad it did :) The insights from their app are very useful (even though I may not like some of them, like telling me not to drink coffee now :D ). I understand my sleep patterns a lot better because of them.

[This review was collected as part of a promotion.] The Ring has been a helpful assistant for my health. The ability to have a device that is lightweight, and minimalist makes me forget that I’m wearing it at all. I love how insightful the device is, been able to track sleep, heart rate patterns and caffeine intake were things I need in a device and this ring does all those factors right.

[This review was collected as part of a promotion.] The ring has helped me triply track how much I’m moving (or not!). It’s also really fun to look at the insight for my sleep and be able tot reflect how certain habits impact my sleep more than I thought. I’m pleasantly surprised at how accurate the ring is at tracking my time of the month, especially as it’s all over the place.

[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 got the ring in april & i mainly got it to try to conceive but all the other features are AMAZING!! i love the sleep tracking & it’s on the money with tracking my cycle. the only thing that i feel isn’t the most accurate is the step counting, i always feel like i do way more but i will look half through my day at work (as a medical assistant) there’s barely 1,500 steps by my lunch so if you’re looking for that aspect i think a fitbit or apple watch may be better. the sleekness of it being a ring was the other reason to get it. i’ve also started to notice some inconsistencies with the battery life & sometimes it will drain very quickly other times it will take like a week and a half or it takes forever to charge. i cant judge it too hard though because the health rings are new technology so i am so sure it will only get better!

[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.] The Ultrahuman has been so helpful in helping me track my sleep. I have a seizure disorder that is impacted by sleep and stress. I like being able to see the sleep deficit and will try to build a nap into my day when I have one. It also holds me accountable when I skip workouts by telling me at the end of the week how much less active I was in comparison to the week before! It's been great and i recommend it to everyone interested in getting a ring.

[This review was collected as part of a promotion.] Been using it for more than a month now, it’s honestly changed my life. I am able to track how my sleep is, my recovery, my stress levels and top favourites - caffeine and breath work (for stress control)
