What Our Customers Say
Steven Griff
Highly recommended
"After spending 3 weeks in the hospital with Covid, after release and home on O2 ring has proven to be a great asset sleeping at night the downloaded graph in the morning provides me with a wealth of information. Now it will wake me when or if my oxygen level drops below a preset warning."
Ron G.
Exactly what I wanted
"I'm a pilot and wanted to get an oximeter to replace my aging finger clip-style oximeter. A couple of features I really like are the vibrating alarm, which I set to high when flying to alert me before hypoxia sets in. And then also - no more batteries to replace. My old unit required a CR2 battery, but this unit lasts longer than I can fly in a day, and then some. I noted that it tracks my oxygen well as I climb to altitude in my unpressurized airplane and had a little fun experimenting with adjusting my oxygen bottle feed at 12,500' MSL from 90% to 98% blood O2 level.
It appears to be very good quality and does exactly what I need it to. Compared to my old unit, my O2 readings are identical, so either they're both off or both accurate, but the readings seem reasonable and consistent and the heart rate sensor matches my Polaris HR belt, so that checks..."
Benjie
So happy to have bought one
"As part of my COVID-19 recovery, I need to monitor my O2 & PR as much as possible. O2Ring gave me that option plus some. The Reports were a big plus to my needs. As well as the alarm feature. I just wished it could be used in the shower and also use it while charging so I could gather a complete 24hrs stat of my system. I recommend this product for post-Covid patients still having O2 stability concerns and for Sleep Apnea patients to learn more about their illness."
Kenechi Munonyedi
A very handy and informative gadget, very useful
"Post- COVID and in the recovery phase, I needed to keep an eye on Oxygen Saturation levels and Heart Rate. That's where the O2 ring comes in. It's very useful to know how these levels change with different tasks and the mobile and desktop apps provide a lot of information and trends. Customer Service has been responsive and helpful. I would highly recommend it."
Barb
Amazing device, better than expected!
"I sleep on my back because of other medical issues and I snore, so my results weren't quite as good as I'd hoped but they are improving. The app report for each use is very informative, detailed, and visually well done. The graphs are very easy to expand and view even for short time periods. The pdf reports are also well done, easy to make notations on, and a wonderful record of my O2 status each night and over time.
The ring is very comfortable to wear. I wear it on my index finger and haven't had any issues with it catching on the sheets or any other problems.
The O2Ring was a little more than I was initially looking for, but I am very happy that I bought it because it provides a lot more information about my health status when sleeping. All pros and no cons after nearly a month of nightly use."
Mark Secord
Great product--and the company stands behind it.
"We bought an O2 ring about 8 months ago and have used it frequently to monitor my wife's SO2 levels--day and night. Having the graphs showing results over time is very helpful. She has been prescribed oxygen at night but it's inconvenient often and we wanted to get data on how much SO2 levels drop. The ring provides perfect data for assessing this, as well as how she does when she exerts herself during exercise during the day. We've shared data with her pulmonologist and he's impressed.
Several weeks ago the display on the device went dark. Wellue responded to my email inquiry promptly and had me do some interventions. When these failed to work they sent me a new O2 ring. Minimal hassle.
I don't give 5-star ratings easily but this one was easy."
Wear O2Ring on your daily basis, for either getting quick readings by spot check or wearing for hours to continuously and accurately track blood oxygen levels (SpO2) and pulse rate (PR). Your data will be displayed in the App in real time.
Our app provides users with unlimited storage, you can easily manage your history data and get detailed trends, the historical data reveals how your body performs dynamically over certain periods of time.
Track The Data Matters Easily
The report shows how long your oxygen is below 90%, how many times during a night your oxygen drops over 4%, and more. You can also zoom into the chart to see more details. O2Ring focus in your key vitals like Average O2, Lowest O2, oxygen drop times per hour to determine the O2 score of your body.

Best Ring: Wellue O2Ring Continuous Ring Oxygen Monitor
Customers found that it improved their sleep quality
The Wellue O2Ring is specifically designed to monitor oxygen level activity
Wellue uses the same type of technology that hospitals do, which makes me feel extra confident that their products are of the utmost quality and accuracy.
The O2 Ring is actually the smallest, ‘medical-grade’ oximeter that can operate continuously throughout whole nighty.
Wearing a pulse oximeter at night is a perfect way to monitor the low oxygen episodes.
I’ve determined that the Wellue O2Ring is the best-in-class option for overnight oxygen monitoring.
If you have any concerns about your recordings, it’s easy to send them to your doctor.

Should You Trust Smart Watch on Blood Oxygen Readings?
we do have studies showing us that reflectance oximetry (used in AW7) is not as accurate or stable as transmittance oximetry (used in fingertip pulse oximeters.) It’s important to understand this significant technological difference.
What Is the Normal Blood Oxygen Level? Is My Blood Oxygen Level Normal?
People with chronic health conditions many need to monitor their blood oxygen level. This includes asthma, heart disease, and chronic obstructive pulmonary disease (COPD).In these cases, monitoring your blood oxygen level can help determine if treatments are working, or if they should be adjusted.
