Customer Ratings & Reviews

I’ve been using the UltraHuman Ring for a little while now, and I can honestly say—it’s amazing. It tracks everything I need, from sleep and recovery to activity levels and heart rate, all with impressive accuracy. The insights are clear, actionable, and genuinely help me stay on top of my health goals. The design is sleek and comfortable—I forget I’m even wearing it most of the time. Battery life is solid, and syncing with the app is fast and seamless. If you’re looking for a wearable that gives you a full picture of your health without being bulky or distracting, this is it. Highly recommend for anyone serious about optimizing their wellness

The Ultrahuman Air Ring is a great alternative for anyone who struggles to consistently wear a watch, or keep track of one (that’s me). The ring itself is extremely lightweight and virtually unnoticeable while wearing it. I’m usually sensitive to jewelry and don’t wear any, but I’ve had no issues with this ring so far. The Good - the ring has an impressively long battery life. I’ve been charging it every 2–3 days, but only because I happened to be near my charger and relaxing, not because it needed it. It tracks a wide range of metrics and seems very accurate, especially for sleep and heart rate. The data is incredibly detailed, sometimes almost too detailed. The app is visually stunning and fairly intuitive, though there is a slight learning curve that some users might find frustrating. The Bad - first off, the firmware. I ran into issues updating it, and a quick search showed I wasn’t the only one. It seems the problem has since been resolved, it left me a bit wary about future updates. Also, while the app is beautiful, interpreting the data can be a challenge. It sometimes feels like there’s too much information and not enough context, such as comparisons to others in my demographic (age, weight, gender). I’m very tech-savvy, but my wife isn’t, so I asked her to go through the app with me. When we explored the app together, she struggled to make sense of it, which makes me wonder if others might find the large amount of data more confusing than helpful. Another downside is the number of in-app “Power Plug” subscriptions. Some, like glucose monitoring, are significantly more expensive than the ring itself. I personally wouldn’t feel comfortable spending that kind of money while firmware issues are still fresh in my memory. That said, I did subscribe to the Cardio Power Plug and have been happy with it so far. On a side note: I had concerns about wearing a ring while playing guitar. Fortunately, I found a silicone cover for the ring that has made a world of difference. The cover prevents the ring from banging against my guitar or other surfaces, and has been key to me being able to wear it for days on end. Overall - This is a fantastic ring and a refreshing alternative to my smartwatch, which I use inconsistently. I love that the battery lasts several days, making it easy to track sleep without having to recharge it every night. It hasn’t caused any sensitivity issues, and so far, it seems the firmware bugs seem to be behind us. I’m excited to check out more of the free Power Plugs (like the Vitamin D tracker) and can’t wait to see what features they roll out next.

The Ultrahuman Ring AIR is one of the latest fitness tracking rings on the market. It arrives very competitively in size, weight, features, and best of all, subscription free. I have worn fitness tracking devices on my wrist off and on over the years, but never have I considered a fitness ring. As someone who has never worn a ring, this has turned out to be an interesting (and mostly positive) experience! In the Box: - Ultrahuman Ring AIR (Sizing done prior to purchase) - Standard Ring Charger - USB-C to USB-C Cable (1 Meter) Setup: Sizing will be done prior to ordering your ring. Ultrahuman can provide a free-of-charge kit with all their pre-selected sizes. I would highly recommend trying some of the sizing rings on different fingers to see what works best, especially during sleep, as this is where some of the best data comes from. Once you receive your actual Ring AIR, you will be prompted to create an account on the app and charge the ring prior to setting up so that any software updates can be done successfully. The app setup was clunky as a couple of the screens to set your current body data (height, weight, gender, etc.) use scroll wheels that if not used precisely will bump you to the next screen. I had to restart the setup process to fix the error in data input. Frustrating. After downloading the app and account setup, I let the ring charge and completed the software update, which only took about a minute. Charging takes anywhere from 15 minutes to 2.5 hours depending on the state of charge. During my testing, I let the ring get to 15% and charged it to full which took just over 2 hours to complete. Upon first glance, app is overwhelming with data and its layout. Over the week of testing, it became less overwhelming plus the notifications helped with interpreting the data (caffeine window, sleep data, and reminders to move, etc.) Usage: As someone who has never worn a ring in their life, it was an interesting few days. I originally picked a size that I thought would work on both my index and ring fingers, but it turned out to only fit safely on my ring finger, no biggie. I chose the Raw Titanium color based on the samples inside of the sizing kit. I think this contrasts slightly less against my skin than the darker gloss or matte colors. I really like it. The ring is extremely light and small. After getting used to wearing it for a couple days, I often forget I am wearing it at times. The best part about it is that it doesn’t interrupt my sleeping by being uncomfortable like a wrist worn tracking device is. I don’t believe I lost any sleep because of comfort, even the first night. Battery life is good but depending on the mode you select, it will vary. I initially selected “Turbo mode” which is constant tracking of vitals and sensors on the ring. This used 25% battery in just 4 hours. This prompted me to change it back to “Chill mode” which is the default out of the box. This netted me 4 full days (day and night) of tracking with 14% battery left before I decided to charge it. Charging took just over 2 hours. There are options to “background sync” and “airplane mode” which impact battery life as well. I like having background sync enabled because it means the app is always ready with your latest data and doesn’t need to refresh upon opening it which takes 3-6 seconds typically. I would expect anywhere between 1 – 5 full days of tracking depending on what mode and settings you have enabled. When it comes to the data and how accurate the data is, I will say there is some variance to the ring’s performance. Some of this comes from the ring itself rotating slightly on my finger so that the sensors might not be in an ideal location for data collection. This has occurred during mowing where I am constantly changing the mowers direction. Outside of this, I think this is some accuracy discrepancies when it comes to other types of fitness trackers for step counts with the ring reading lower than wrist worn devices. I also wish the heart rate sampling was taken more often in “Chill mode” as there are sometimes large gaps in data on the graph which seems too excessive. I really have enjoyed the sleep tracking aspect of this ring given it has been very accurate with times (starting and ending), sleep stages, and recommendations on ways to improve sleep quality. Overall: I never thought I would enjoy wearing a fitness ring like I have with the Ultrahuman Ring AIR. I was someone who wore a Fitbit for a couple years, but I wasn’t one to wear it at night due to comfort issues and its general comfort wasn’t great. With sleep tracking a valuable piece of data, I decided to ditch the entire fitness device idea. With the opportunity to try this Ring AIR, I am back in the fitness tracking game with the added benefit of sleep tracking. I never thought I would be one to wear a ring, but this would be my go-to strictly for comfort and sleep tracking even if the daytime data isn’t as accurate. Pros: - Small, Lightweight - Attractive Design - Sleep Tracking Data - Qualifies for HSA Purchase Cons: - Step Count/Data Accuracy - Battery Life (Turbo Mode) - App Setup/Layout - Scratches Semi Easily

The Ultrahuman Smart Health Ring is a revolutionary tool for tracking and improving overall health. Its sleek, minimalist design makes it comfortable for all-day wear, while offering accurate insights into heart rate, sleep quality, stress levels, and metabolic health. The intuitive Ultrahuman app seamlessly syncs with the ring, providing actionable, personalized recommendations to optimize your lifestyle. With excellent battery life, water resistance, and a focus on holistic well-being, this ring is a perfect companion for anyone looking to take control of their health and fitness journey. Highly recommended!

I have worn this ring for 2.5 weeks straight prior to reviewing it, taking it off (more than briefly to do things like washing my hands or applying lotion) only to charge it, and that only happened twice in the 2.5 weeks of use. I am a long time wearer of Apple Watches (and prior to switching to Apple Watches about 6 years ago, I wore various Fitbits), so I will be using that as a comparison throughout my review for the ring. As a caveat, I don't usually wear rings, so keep that in mind while reading my review - for someone who is used to wearing rings, some of my cons/complaints/concerns relate to the fit and comfort of the ring might not apply. Pros: - battery life - even on "turbo mode" (which, according to Ultrahuman, is supposed to drain the battery quickly) the watch battery lasted a full week without being charged! I can't even make it 24 hours on a single battery charge for my watch - lots of interesting information gathered from 1 single finger - from stress rhythm, temperature, sleep, UV/Vitamin D exposure...so much is being measured! Cons: - I need a half size, and I'm sure I'm not the only one who has or will run into this issue. I had the sizing kit, and the smaller size was just tight enough that it was hard to get off without some effort, but the larger size slipped off easily (especially when wet), which makes it hard to get accurate readings, according to Ultrahuman's directions (I went with the larger size because I didn't want the ring to get stuck on my finger without being able to get it off if needed) - It is bulky, awkward, and very masculine looking. Again, keep in mind I don't normally wear rings, but wearing it on my right finger completely prevented my pinky finger from lining up with my ring finger (pictured), and it was an annoyance throughout the day. - Easily scratched material - even before a full 24 hours of wearing it had passed I was noticing a lot of scratches on the ring just from every day wear and tear. After 2.5 weeks, pretty much the entire ring is scratched up, and I just don't think it would be durable to wear it all day every day until the ring needed to be upgraded or replaced. - The app. Oh, the app. It is a mess. There are 5 different "tabs" on the bottom of the screen - and only 1 is applicable to the ring. One is a Zones (Ultrahuman's social network - I didn't explore it since I didn't have anyone to connect to, but it looks like it is their version of how you can share your activity information on Apple Watches with friends), one is your "profile," and the other two are just there to try to sell you their other products. But that's not the end of the mess. The UI seemed very overcomplicated and busy, the graphs/modules moved around based on the time of day, and there's not a lot of explaining of what all of the graphs/modules were measuring or how to change them. - Accuracy of data. I am not entirely sure the data is accurate. I frequently spot checked things that both my Apple Watch and the Ultrahuman ring measured, and there were frequent major contradictions between them or things that I know for a fact were wrong (for example, the ring would say I was asleep while sitting on the couch watching TV even though I know I was 100% awake). I have been able to measure the accuracy of data from the Watch against actual medical devices (i.e., an oximeter for my pulse, sleep data against a sleep test, etc) and as a result generally consider the Watch to be accurate, so when I saw drastic differences in the data between the Watch and the Ultrahuman ring, I was a little weary. - Charge time of the battery - to fully charge the Ring from dead (or basically dead), it takes over 2 hours, and at least one of the times I charged it, I kept having to adjust the ring on charger because it would stop charging. I feel like this Ultrahuman smart ring left a lot to be desired for me. If you are wanting fun insights into your health (that may or may not be completely accurate), a smart ring might be the right move for you. Unfortunately, I think this one missed the mark, and I can't recommend it.

Years ago, I used to wear a smart watch, but I quickly learned the downside of having a small version of a smartphone on my wrist and wanted to be less connected. I ended up replacing my smartwatch with a health tracking watch, but noticed it lacked a lot of the technology a smart watch provided. When I learned of a smart ring which provides a plethora of information to fill that void, I was excited to try it. This ring is designed to be used on either the index, middle or ring finger. I choose to wear my ring in place of my wedding ring since it is more comfortable and stays in place. I also choose the Aster Black color and could not be happier with the finish and color. I have been wearing this ring for about a week and have been pretty amazed with all the data and suggestions the app provides. Unsurprisingly, I noticed the step counts and fitness tracker varied slightly from my watch and phone. However, no tracking device is perfect. How you use the data to make healthier lifestyle choices is the most important aspect. The app is amazing and I was thrilled there were no monthly/yearly subscription fees. Ultrahuman provides so much information on their app, but makes the data not seem overwhelming. The color choice for each section and the ability to choose what data you want to access makes the data more valuable. I also am a big fan of the suggestions the app gives to help improve the scores. The only improvement I would like to see would have an option to charge the ring when it is on the finger. The battery life only lasts a few days and data is missed when I am not wearing it. I would highly recommend this ring. The data it provides is very useful, the app is thorough and organized, and all of this is provided without needing another subscription.

Hardware 4/5 - Looks nice and clean like a ring should not anything over the top like some other manufacturers. App 4/5 - Love all of the insights. You want data? They got it. My favorite was how it adjusted my caffeine intake window based around my recovery and sleep. It gives you an idea of when adenosine is fully cleared out of your system so caffeine actual has its full effect and doesn’t just make you tired again. And yes, this made a huge difference in energy levels. Battery 5/5 - This product is better than other rings that claim longer battery life and I will explain. I chose this smart ring even with a lower battery life vs the competition because the frequency of readings from this ring is much higher than the competition. You are trading a day or two of battery life for higher data resolution. I also learned that other rings will only really take any meaningful data during the night and dial back almost all readings during the day. And honestly charging these rings up is so easy just pop it on during a shower and you’re good for four plus days. Summary - if you’re looking around for a smart ring that will do it all one doesn’t exist, but this little thing comes pretty dang close. Give it a try and see for yourself.

I really like this smart ring — it’s lightweight, comfortable, and easy to wear all day without noticing it. The health and recovery insights are clear and useful, especially for sleep, activity, and overall readiness. The matte gray finish looks sleek and premium, making it feel both practical and stylish.

I’ve been using the Ultrahuman Ring for a while now and overall, I’m very happy with its performance. The ring works really well in measuring health metrics — accurate, consistent, and very insightful for tracking my daily activity and recovery. That said, the matte black finish seems to scratch quite easily. For a product in this price range, I was hoping for a bit more durability in the exterior coating. Functionality-wise it’s excellent, but the appearance starts to show wear sooner than expected. If Ultrahuman can improve the coating quality, this would easily be a near-perfect product.

This ring provides extremely accurate information. The charge lasts for DAYS. The app is user friendly as well. Set up is easy

The Ultrahuman Ring is a game-changer for tracking your fitness and recovery—it’s sleek, lightweight, and gives you real-time data on how your body’s doing. It’s perfect for anyone looking to level up their health routine with smart insights and a solid, long-lasting battery.

First one failed, replaced from manufacutrer in the first week. Five months later, the ring is still going strong. I don't baby it and only remove when I shower--but not for fear of water causing damage but because that is when I charge it. I purchased this mostly becuase I'm becoming a crusty old man and I wanted to track sleep and activity without a watch style device--and without a subscription. I generally like the app, though they constantly want to sell you other stuff which is annoying. Ultimately, I'm not certain how accurate the data is or how useful, but as a baseline for tracking sleep and activity it seems pretty consistent. Also not sure a bout long term reliability.

I really like this smart ring — it’s lightweight, comfortable, and easy to wear all day without noticing it. The health and recovery insights are clear and useful, especially for sleep, activity, and overall readiness. The matte gray finish looks sleek and premium, making it feel both practical and stylish.

Purchased this product because I didn’t want to pay for the Oura ring subscription fee. Ultra human ring is comfortable and nice an light. Set up is easy the app is very clean and user friendly. Captures my sleep accurately like my Apple Watch. Picks up on my jogging. Plus you can log different activities. It does skin temp, HRV, V02 max. Sleep captures rem an deep sleep. Gives you a sleep score and readiness for the day. Plus has plug ins that you can use for free. For the ladies it has cycle tracking. You can pay for the AFib tracking if you want.

I received the Ultrahuman Smart Ring as a Christmas gift and I’m very happy with it. It was easy to set up, download the app, and pair with my phone. I really like it for all the sleep data it gives me, but it’s great when I go to the gym as a workout tracker. I’ve really enjoyed exploring the app and seeing all the amazing things it can do. Highly recommend!

Works great, good battery life. Very comfortable to wear. I really enjoy the app and all the great info it gives me without a subscription cost! It also gives me suggestions to improve my numbers, sleep, and other health items. Highly recommended!!!

Pros: No subscription plan. Seems to be very accurate when on Turbo Mode. Syncs easily. Tracks data accurately and clearly. Cons: Bulky on smaller fingers. Some of the recordings aren't necessary. I wish that you could eliminate some of them to save battery life.

I’ve tried a few wearables, but the Ultrahuman Ring completely blew me away. It’s sleek, super comfortable, and I barely even notice I’m wearing it. The insights it provides on sleep, recovery, and overall health are next-level—way more useful than just counting steps or tracking calories. I love that there’s no screen to distract me, just solid data in the app that actually helps me improve my health. Battery life is great, the design is durable, and it feels premium (I bought the gold one). It is also really easy to connect to blue tooth and charge, not much hassle. Couldn’t be happier with it!

Very good product highly recommend. Tracked all of my health items at no additional cost.

This product has a lot detailed data and no extra fees. The only thing that bothers me is that the ring is so bulky or thick to have it on your finger.
