An effective and comfortable way to measure SpO2
I found the O2 Ring Monitor quite easy to use. Perhaps mostly critically, it is comfortable to wear during the night. The device provides a “Sleep Score” and an “Oxygen Score” after use. I would like to know a bit more about how those scores were derived. The symbols displayed on the ring are mostly self-explanatory, but I would also have liked a better description of them in the accompanying instructions. While it’s a little bit quirky, the PC app provides a useful record of the Ring’s findings and is a feature I particularly like.

A dependable and effective monitor. Comfortable enough to wear overnight.
I waited a few months before reviewing this product to test it out and make a determination on its quality, dependability as a monitor, and effectiveness, and I have to say I’ve been pleased so far. I did have to return the first ring I received, which didn’t seem to work correctly out if the box, but customer service was a breeze to deal with and I had a new ring at my door before I had even returned the original. I did have to play around with placement as I found that personally speaking, placing the ring on my middle finger provided the most consistent readings. I wear it comfortably throughout the night to record fluctuations in my oxygen and heart rates. The companion app was easy to install and sign up for and gives a good array of these readings organized by date. I would say the only con is that it can be a little difficult to determine the battery level, as it’s not immediately obvious, but all in all, this is a great product.

Doesn’t last forever.
I purchased one of these on 16Dec2020 from Amazon. It failed earlier this week (24Jan2026), so I got just over 5 years of use out of it. During those 5 years I estimate I wore it roughly 40% of the time at night. The failure ended up being that it wouldn’t turn off when I took it off my finger. The red light would stay on. I could manipulate it enough to get it to turn off and synch data but when I let it go, it would turn on again. i liked the data and results that I purchased another one this week. The battery on mine easily lasted through an 8 hour night yet when it failed.The hole for fingers is very small and I can only wear it on my smallest finger to avoid cutting off circulation. It is also quite bulky and because it is on my “pinky” finger, it rotates easily. I wish they made two different sizes.

Good product. Easy to use. Printable reports can be shown to your doctor. Good way to test for sleep apnea

Not reliable and no support!
If I could give no stars I would.I only had the ring a few days and all the language switched to Chinese.(?) I have tried repeatedly to connect with their ‘Support’ team as they said that should be done before sending it back. I have sent them screen shots of what I’m getting on my phone. They sent me instructions on how to change the language, but as it’s in Chinese(?) I can’t do that. I want to return it via Amazon but now I find out that I’m too late by one day!!!So frustrating. They are now ignoring me and not responding. I should have ignored them and sent it back!Don’t be fooled by their ‘support’ team as they do not support at all. They didn’t offer me an exchange or my money back!

Good Device, Poor Analysis Software and Failed After 16 Months
I like the Wellue O2 Ring for its comfort to wear vs oximeters like the Contec CMS50I wrist oximeter and others. My biggest and most disappointing issue with the O2 ring is the software, both the Android app and O2 Insight Pro are awful by comparison to the Contec SpO2 Assistant software that comes with CMS50I. I have been trying to figure out how to convert the Wellue file format or csv to SpO2 files without success as the SpO2 file format is not documented. SpO2 Assistant allows me to manipulate both the analysis and the display parameters for SpO2, pulse and the perfusion index and has various useful summary reports from which to choose.Both oximeters seem to be equally accurate. The biggest plus for the O2 Ring is it is the most comfortable recording oximeter I have found to wear while sleeping, and it has a motion sensor which, with better software assuming proper sampling techniques, would help identify respiratory effort related arousals (RERAs). Unfortunately the Ring data output is of only of marginal use to me. People using a CPAP machines could download the Wellue files into OSCAR software available on the Apnea Board website which would allow them to see the oximetry in a more useful format and in conjunction with the data from their CPAP, but even OSCAR is not as robust as the SpO2 software for oximetry analysis. The biggest pluses for the CMS50I are the software, as well as the perfusion index and bluetooth capabilities, the biggest negative is comfort. The professional overnight sleep lab study software, which I have used in my neurologist’s office, is even better than SpO2 Assistant and would be my model for building software for the O2 Ring.Update: Ring failed after 16 months, downgraded to 3 stars – see photo

Good enough to convince my doctor!
This review is for the O2 sensor ring which I purchased in 2023. I used that ring nearly everyday for 2.5 years. It worked very well. Results from that ring convince my doctor to prescribe an oxygen concentrator which i use nightly. The ring showed that with the concentrator, my SpO2 average was 94% with minimums of 90%. Before the concentrator, my SpO2 average was below 90% with significant durations in the low to mid 80%. I just replaced the ring because the battery stopped charging after heavy usage. The phone application would be the only weak aspect of this device. It did enable retrieval of nightly graphs and statistics. I could not download the data to my computer. It should be noted that this device does not work properly during exercise. I obviously recommend this ring. I just bought a new one.
