This product and the accompanying app are very clean, very modern, just what I was hoping for. Connecting is automatic, downloading data is automatic, etc. Form factor is small, comfortable, well designed. Very, very happy w/ring versus older wristwatch + finger clip product, the other option I considered.Here is my experience:Turns on automatically when you put in your finger, counts down to turning off / saving data when you remove your finger.Downloaded app for my iPhone from Apple store. App comes up searching for device automatically. On first use had turned on device with finger (then removed, stays on for awhile), app found device & showed picture of ring. Clicked on picture of ring & was paired.Clicked “Settings” at bottom and turned on heart rate alarm, turned off oxygenation alarm. Easy to use & clear.Put ring on, went to bed. Took off when got up in middle of the night, then put back on. So 2 data sets created.In morning, app found ring automatically because it was on, said “loading ” and displayed report when done. Both data sets were loaded. Clicked on each data set to see its respective report.App has 4 main options across bottom, “History” which is where your data sets / reports are; “Dashboard” which displays real-time O2 & HR status when ring is on; “Settings”; and “Discover” which searches for the device.BTW when ring is not on, click “Offline Use” at the bottom of the app screen to review data etc.Ring does wake me up okay on the default, medium intensity vibration when my HR drops below 40. Feeling better in AM. Very grateful for this product :o)PS used the coupon available on the Wellue website, saved $10, may still be there

I only write reviews when something or some service is either 5 stars or 1 star, and this O2Ring gets my 5 star vote.Now after a few nights using the O2ring, which vibrates if my blood oxygen goes below 90, it’s helping me to prevent sleeping on my back (and snoring). As a test, I disabled the vibrate alarm and my blood oxygen did indeed suffer (when I am sleeping on my back and snoring).I thought that I would definitely prefer the PC reports and CSV data saving capability, but the iPhone app really does work quite well. It has 30 min., 1 hour, 5 hour and 10 hour zoom windows, and while no zooming (2 finger stretch) is possible, it does support “wiping” quickly through the 30 min. windows to see things closer up.I hope that this review helps you.Jim

This monitor is version 2 for tracking oxygen levels, which is what I need it for. The first version was exactly what I needed and I wore it for a year. It even went through the washing machine and still worked. Sadly to say I broke it so I reordered the new one.I didn’t know they could make it better but they did. Below are some on my observations* fits the thumb or finger comfortably* gives accurate readings* it’s small enough to wear in public without drawing attention* stays on your finger unlike the clip on o2 monitors* easy to dowload to the software* pairing was easy* the reports are benificial to your doctorIn addition to the product being exactly as expected and more, the company take a personal touch to their product. When I broke my first one I contacted them and their response was timely and helpful. I wasn’t sure what to expect for customer service but I’d give customer service 5 stars too, if I could.Over all this monitor does exactly as advertised and the company is great to work with. Very high recommend if you need a product like this.

I bought this product to monitor my o2 sat during sleep. The product is comfortable to wear, unlike the clip on style o2 monitors with wires. Battery life is good and appears it could probably track for 2 nights before being discharged. iPhone app and PC app work well, though the iPhone app is a bit more polished. I like the PC app as it generates nice printable reports and you can enter notes into the report before saving.I did notice one thing about the product that others may want to know about. I tried using it as a general heart/o2 monitor during exercise, however, the sensors get overloaded by sunlight when outdoors, so it will not work well in direct sunlight and also the display is not bright enough to read outdoors. I didn’t really purchase it for exercise, only as a sleep monitor, and it works great for the sleep o2sat monitor functions.Overall, it’s a great product for sleep monitoring and I am very happy with my purchase.

The ring is designed to be adjustable but it’s too big for my fingers (I’m an adult female with fairly small hands). When I first started using it the O2 saturation was averaging lower than what I was expecting (based on my last doctor visit and experience as an RN). I experimented with different fingers and got the best reading on my thumb but it was still too variable for my liking. From a post on a CPAP forum I got the idea to try it on a big toe and the readings there are much more accurate. However, the device has fallen off twice in the 4 or 5 nights I’ve worn it there, so that’s something to consider if you’re a restless sleeper (like me). The app has worked well, which is good thing because a device like this is useless without a good app (I’m using the Android version). I just wish the ring fit better. I’m going to try a different device and if that works better I’ll pass this one along to my brother, who has bigger hands than I do, because I’ve had it too long to return it.

My rating is 4.5 stars. I have been using this for about a month and I have learned quite a bit about my sleep patterns. The vibration works well to get you to adjust your position when oxygen level drops. The app is easy to use and provides good data. One suggestion to the app developer – currently the app shows the amount of time spent below 90% oxygen saturation. It would be very useful to add another metric with time spent in the orange range, which appears to be anything below 95 or 94%. This seems to correlate with how well I feel when I wake up.

1) It detected my sleep apnea. In some cases very rapid drops in O2 with accompanied high heart rate. This correlated with my very poor sleep pattern and constant waking up at night. I had a “borderline” apnea test done at a lab that charged $10K and told me I was ONE POINT AWAY from getting a CPAP Rx!!!!! They only monitored one night, and that night I actually slept well. This ring has shown that I have some nights that are ok, and others that are really really bad.2) I believe the vibration setting maybe does help me to wake up. I used the default threshold of 88%, and that was about the lowest it would go because I would wake up. So I lowered the threshold to 75%, and sure enough I started to have some drops that went down to 75%. So that leads me to believe that the vibration setting actually does help to wake me up and at least once I awoke while it was vibrating.3) The android app and setup are TERRIBLE. If it is able to display the settings from the ring in realtime on the “dashboard”, then why can’t it just log the data realtime into a histogram display? It took me a while to figure out how it actually gathers the detailed logs. Here is what you need to do, hopefully this helps you:a) DO NOT PAIR the device via BlueTooth. It does not require pairing. If you pair it, you will have to factory reset it.b) Leave the device on a USB charger until you are ready to sleep. It won’t last much longer than one night sleep.c) Slip the ring onto a finger and close/re-open the app (if still running, it will likely say the device is disconnected and won’t ever connect until the app is INITIALLY opened)d) Make sure the O2 ring shows connected and shows data in the dashboard. You want to make sure the perfusion index is at least 50% to get accurate readings. You may have to adjust which finger you use.e) Set the vibration level and threshold. I just set the vibration to maximum.f) Sleep.g) When you awake, unlock your phone and make sure the app is opened and on the history screen, then take off the ring. It will start counting down from 10…9…8……. keep it close to your phone and do not expand the band at all. It will start the data transfer to the app of all the events gathered over the night. If you expand it, you will trigger the ring starting a new activity.Unless the device is deliberately falsifying data, I think the combination of SpO2, Heart Rate, and Motion detection is a pretty good indicator of actual events occurring while you sleep. In my case, my resting heart rate is normally around 60BPM, but when I am having an issue it shoots to 95BPM. My SpO2 drops rapidly and the motion is detected around the same time.I will show all of this to my doctor, and recommend that he never again use the $10k per night (not covered by insurance!) sleep study lab ever again. THEY FAILED!I also was sick with pneumonia prior to having this ring. I did have a manual single shot pulse oximeter though and was watching my SpO2 levels drop down into the 70’s! If only I had this ring at that time! Given the current risks with COVID19 (SARS-nCoV2), I think it is a very good investment to have something like this at home to monitor someone in your family that is sick. If their SpO2 drops considerably, that data will help you to know when you need to run to the ER or not. Maybe have another “certified” pulse oximeter on hand (no pun intended) to verify the numbers?I am not a doctor, and I believe this device says not to use for medical purposes. Yadda yadda yadda…

I got this product as a gift for my husband. He has been snoring for years and postponed multiple appointments with his doctor. Recently he complained of headache and felt not refreshed in the morning. It kept me up during the night. I tried to wake him up when there was long time stop of breathing, but I can’t watch him the whole night. I started looking for a simple oximetry online, then I saw this product. It is out of my budget. However, I was thinking that if it can wake him up then it’s worth it. It turned out to be the best gift ever for him. It looks fancy, easy on, easy off. We can see the O2 saturation on the phone easily. We didn’t expect that his saturation was as low as 78% during the night. We set up the alarm level as 80%. The vibration successfully woke him up without bothering me. LOL. I have better sleep and he feels much more refreshed. We also made appointment with doctors asap as we see how bad the problem is. We want to prevent the accident from happening. Thank god, this O2 ring prompted us to take better care of ourselves.

I use this in conjunction with my fitbit and Snorelab app. I wear it at night. If you look at the results and write down the time intervals of sustained low O2 and compare it to your Snorelab results you will see that the low O2 intervals coincide with stopped breathing (apneas) on your Snorelab results. The Snorelab app records your snoring and is awesome when combined with this and very easy to use. Once I realized how they coincided I used my wifes cell phone to videorecord me sleeping all night. It showed that everytime my Low O2 levels and apneas occurred I was sleeping on my back. Now I wear a device that prevents me from sleeping on my back and my apneas are gone! Im sooo happy. I also wear a mouth device that vastly reduces my snoring. I had a sleep study done before monitoring all of this on my own and it showed moderate sleep apnea on the first night and severe on the second night and prescribed me a cpap machine but I really wanted to avoid that if possible. This worked so well for me that Im not going to get the cpap machine unless for some reason my sleep apnea and snoring return. Btw I had read that drinking alcohol before going to bed increases the severity of your sleep apnea that night and its true. I was amazed at how much worse my snoring and apneas were after drinking. I wouldnt have been able to figure any of this out without this device. My oxygen levels are so much better now and I actually feel rested when I wake up in the morning. Anyway I love this device and its worth every penny.
