The company really stands behind their products with excellent responsiveness to questions and the software works great. It would be great if they could integrate the results in Apple Health!
Gary B.
Very easy to set up.
Provides an easy to interpret summary on your phone when synced.
I am very glad I bought it!
Ricky O.
Worked right out of the box, easy to use. I set it up for PC and had no issues with connectivity or the software. Very happy with it's small size and ease of use, now I know how my CPAP settings affect my sleep.

My husband is a lung transplant recipient, 10 years out. This device has made it possible for him to monitor his oxygen levels 24/7 in different situations. He can set the level and the ring will warn him with a vibration if his oxygen drops to that level. It works, it is amazing!
Thank you so much for making this available!!
Earl B.
This is an awesome little device that I have shown to a few folks who use CPAP machines. What a great way to assess what sleep times and sleep behaviours impact breathing/blood oxygen!
Much better than pure motion and sound detection from traditional wrist wearables .
In less than a week I realized i just had to avoid sleeping on my back and I was fine..
In fact this device revealed that even when I am awake but laying on my back reclined while watching TV causes a breathing impact and a Blood oxygen reduction ..How about that? Wish the battery lasted for more than a night and that the motion sensor was a bit more sensitive but this is a great little device and I recommend it to anyone I bump into when sleep, snoring, or CPAP topics come up ..
Tim H.
This device gives excellent feed back every night letting me know if my cpap is doing it’s job. I put it on my left thumb and dot even know it’s there.. unless my oxygen hrs to low and then it wakes me up. Every cpap user needs one.

The Wellue 02 ring is a great way to monitor your sleep. I have sleep apnea, and I needed to monitor my sleeping events. I can now share the data, which is free by the way, with my Doctor, to evaluate the rest that I need during sleeping. I have used it every night now for 14 consecutive days, and the app works great to see your results. On the PC, you can download the data directly from the 02 ring, while it is connected with the USB cord to the PC. It allows you to generate a data base of events, and you can edit information, you feel is useful. This is very handy, when you need to try different options, while trying to improve your 02 Score, or settings on your device. Just make sure you do not have the app running on your phone, when you are trying to download the data directly from the 02 Ring to the PC, because it will not download, so close the app first, then press download on the 02 Insight Pro application on the PC when it is running. If there was one thing I would like to see added, is to please add a SP02 ratio below 70, as my sleep studies have shown my Sp02 to fall as low as 60. If you could add that additional 10 or 20 percent to the data fields for both the app and the PC application, that would really be helpful, in a firmware update. The customer support is fantastic, and they respond in a timely manner. Send them your data, to view, for support or suggestions, if you have any questions. Great Product. Thank you!!!
Daniel B.
The computer program needs to have a header that can be used by labratories to put their info , company name and phone and address.
it also lakes the ability to type in different patients info. know it only allows on patient ..
If you wont this product to be used in clinics and labs you must make these changes.
I have tried to reach out via e mail but have not had any resposes.
I would buy 10 for my lab if these simple issues where corrected

Very useful device. I appreciate the vibrating alarm that you can set to alert you to a chosen level of oxygen saturation.
As a doctor myself I am keen to use this on patients who might have as sleep apnea.
Richard R.
Bought the ring to monitor my spo2 at night while using an oxygen concentrator. I,m now at almost sea level and off grid, so I can't use concentrator. So far, I don't need oxygen at night here. This has been very valuable information for me! Thank You!!!!!
Scott C.
Very interesting results after 1 week of use. Night 1 pic on left shows problems that worried me. So I took some corrective action in the first 6 days (better meal at dinner, not eating after 7pm, nose spray, better hydrated, changed pillows, etc), took advantage of the ring feature to buzz me when my SPO2 dropped low, monitored every night, and last night's results are on the right. It's a noticeable improvement, and more importantly, I feel much better. I'm data-driven generally, so this device is great for me.
Andrew P.
I can see what is going on as I sleep. I can print out copy for doctors, and for me it helped me not take a higher milligram of meds, because my heart rate was too low in my sleep. Thank GOD I had this.
Willie W.
I purchased the 02Ring for my spouse who has been diagnosed with COPD. She has been using the Ring for about two weeks and is very very excited about the freedom she now has. She can now take showers and go short distances in the house without worry about oxygen getting too low unknowingly.
Bernard M.
Your responses are fast, but please stop using jargon or computerize, as many of your customers are older. I do not have, or ever intend to have, a smart phone, so all my printed directions are in a couple of paragraphs (no. 4). No explanation of symbols, no notice that the battery must automatically recharge before anything else can happen, no notice that the O2Ring (not the "device") must be unplugged and then replugged, somrtimes a dozen times, before the computer finally acknowledges the O2Ring. My doctor asked "What is the ODI?" Suggestion: (1) Put up your own video so customers don't have to rely on the three present uninformative videos (2) Provide the information so that your customers can calculate their AHI and hypopnea occurrences. Doctors like to prescribe CPAP and oxygen. Your device, oops, O2Ring can allow your customer, or their teenager, to calculate the user's AHI. An AHI less than 15 precludes the need for the expenditure of hundreds and hundreds of dollars, plus a lifetime of inconvenience. By the way, the Pulse Rate graph paper should be relined. Easiest way would be to have six blocks horizontally, instead of the present five.
Michael K.
Recently fitted with a CPAP machine for good reason but I don't trust machines to evaluate themselves. Your device works comfortably, reliably and reports are full and detailed. It's a long way towards feeling medically secure while you sleep. The HR rate and O2 alarms are wonderful!
William H.
I use the ORing while sleeping. In the short time I have been using the device, the ring together with the App informed me that I have significant drops in my blood oxygen saturation. I also learned that my Oxygen level drops to dangeriously low levels during the night.
Carlos S.
It is very comfortable to use, easy to see and the software for Windows and Android works in a straightforward manner.
So far I am very satisfied.
Kim S.
This device works exactly as advertised! It exceeds my expectations in terms of form fit and function. On the first night this device confirmed my suspicion that my heart rate was going very low causing circulation issues during my deep sleep. I was surprised to see that my blood oxygen saturation levels still remained high during those periods of very slow heart rate. I recommend this product. Best regards KS
Luwiena O.
Wear it all night. Shows me my oxygen level every morning, and puts my mind at ease.
Comfortable on the thumb. Do not feel the device at all.
Downloads information to my iPhone.
A very good device, and I highly recommend it.
Barbara C.
My husband was not sure if I was breath at night hence the purchase. Comfortable to wear, took a while to work out how to download and get readings, wish the battery had a longer life. I am 70, may account my lack of Tec knowledge. Overall would recommend this product.
Ming yu C.
It’s very nice toy to check.
Brian S.
Works as advertised. I have actually set off the vibrating alarm a couple times and couldn't wait to see the results. I can't really speak to the accuracy but it does seem to be on the higher side. It is interesting to see how my heart rate and O2 levels drop as the night goes on. Can also tell when my movements increase towards the end of my sleep cycle. Wish there were a few other things it could monitor, but I understand why it doesn't.
Doris S.
I can’t wear a cpap or a snore guard. I have found the 02 ring is better than nothing in that it will arouse me when my 02 is low. I am planning on letting my daughter try it when I see her at Christmas and will order her one if it works for her.
Jose D.
I already write to Helen, about the 02Ring.
Zahid R.
It is working great for me. Providing me vital data through app. It helped me understand the difference between sleeping without CPAP and with CPAP. Now I am trying to improve my lifestyle and increase the oxygen level while I am in sleep. I think people with sleep apnea can benefit from this ring and app.
Drago C.
I tried several products for this purpose without of success. O2 Ring is very reliable, I think it can be used by professionals. My best recommendations for OSA prevention.
Dana G.
I absolutely love my O2 ring tracker! I live at 10,600’ elevation and use supplemental oxygen during sleep. The ring tracker gives me peace of mind knowing that if my O2 levels drop below 88%, I’ll be awakened by the ring vibration. (Note: The threshold is user adjustable from 80%-95%.)
Also important is the comfort. I’d done an overnight oxygen study in the past, and the pulse oximeter bruised my finger. With the ring tracker, it’s so comfortable that I’ve sometimes awoken in the morning forgetting it’s even on.
I find the sleep report that can be downloaded to my PC to be especially helpful. It gives me detailed hourly graphs that I can take to my doctor for review. The report is comparable to an actual sleep study report. (See pix)
I highly recommend this monitor to anyone at altitude and/or with oxygen issues.
Liis V.
I like O2Ring very much. It looks good, is comfortable to wear and it doesn't come off during the night. The setup is effortless - just put it on your finger and open the app. There is a lot of data in the app and it is possible to zoom into the graphs. Great product!
Richard C.
Just got this yesterday. Was completely surprised by the quality. Did not expect it! :)
Worked flawlessly right out of the box. Perfectly comfortable overnight. The graphs in the
app are awesome! Everything was pretty much intuitive to use. This is my new security
blanket for when I get off my CPAP machine. (I'm having my nose and teeth fixed)
Very nice!!
Jack M.
I was diagnosed with sleep APNEA after a one night sleep study. The sleep center recommended my using a CPAP machine. Subsequently, my O2Ring showed that my breathing performance varies a lot from night to night. What kind of night was the basis for my diagnosis? The Cleveland Clinic Sleep Disorder Guide provides a list of prospective alternatives for mild to moderate sleep APNEA. The O2Ring allows you to objectively measure your breathing performance while trying these alternatives and making adjustments until you get it right. In my case, I may NEVER need a CPAP machine. I do need to avoid sleeping on my back and use a nasal spray every night before bed. I consult with my physician. Everyone should consult with their physician. Bring your O2Ring reports to your doctor visit.
Bruce S.
Great product. Really give me and my doctor a better understanding of my sleep.
Easy to use. Comfortable to wear,
Christopher V.
Good unit. Works accurately and stays on my finger comfortably. My wife and I take turns using it to track our 02 levels. Only 4 stars because I believe the price point is a bit too high.
Robert B.
I recommend this to everyone who has issues with sleep apnea or even just sleep issues.
Robert B.
Works well, very helpful in deciding which sleep apnea therapy works best.
Eugene D.
30 days use and so far its working great. Looking forward to more detail and updates to software.
Increase the notes section by expanding length of words allowed.
Increase details of heart rate.
But Im liking what Im seeing.
Shelah P.
It seems to work well but always feels very loose on my normal sized woman’s hand.
Rhonda G.
It has saved my LIFE ONCE !! I wear it every nite
( the only thing I would add ... would be able to add 1 or 2 #’ to its emergency notifications to others that your having a emergency) not just recorded on your phone ,) Thank you
Robert A.
Easy and comfortable to use. I like the easily readable and shareable reports using the mobile software.
Ronald F.
It works better than expected. My regular Dr. And my Heart Dr. Are amazed it showS I am trying. I have bad sleep apnea.
David W.
I would like to be able to delete some of the data, but cannot figure out how to do that. I also had an evening where it showed the wrong time even though my phone had the correct time, Very minor issues.
Marios P.
Works great!!!!! Highly recommend it
Heather B.
Never reads and always blinks. Tried everything and still nothing. Very unhappy with spending this much money and it doesn’t work.
David B.
Easy to wear. Seems to be very accurate. Great tool to evaluate sleep.
Cristina
I use both the vibrating O2 Ring and the audible alarm Oxylink. My hands are large but they both fit comfortably on my pinky finger. I choose my non-dominate hand for ease when writing or performing other tasks. I adjusted to the device quickly and it is never cumbersome or in the way. I forget I am even wearing it unless it signals me. However, do be careful when dressing not to let the device catch and hook on your sleeve.
The vibrating ring, like a vibrating cell phone setting, is best for meetings, sleeping and loud environments. It would also be best for the hearing impaired. By contrast, the audible alarm Oxylink is terrific for every day living. It is invaluable if others need to be aware of your O2 or pulse levels, such as with children or the elderly. My wife likes both rings constant monitoring because she doesn’t need to worry and remind me to check my levels as she did with the finger-tip Oximeter.
The cell phone app is an excellent source of information for you and your doctor. It provides a history that allows you to recognize trends, patterns and times when your levels are more likely to fluctuate.
I recommend these products and I believe the cost is reasonable for the health benefits and peace of mind. I might add, This company has been easy to contact and very helpful. Excellent customer service with exceptional products.
John P.
I have found the Wellue O2Ring Oxygen Monitor to be great for providing a measure of my sleep apnea and extremely comfortable to wear as it does not disturb my sleep. Further, the iOS App is simple to use and keeps a great sleep record showing blood oxygen saturation and heart rate over time, counting blood oxygen drops of 4% or more and blood oxygen score.
Grzegorz B.
I write after 2 weeks of testing the device. I bought the device on 10.2019 and O2Ring met my expectations in 95%. A huge plus for which I bought this device is the frequency of measurements (every second) and the accuracy of measurements. the device is not big, it is very comfortable. After a minute, you forget that you have it on your finger. Vibration in strong mode wakes you up from apnea - that's a big plus. At first glance, the application seems quite poor, but after a few measurements I find that it is sufficient and you can use it without unnecessary embellishments. As for me, the only downside is that it is not integrated with Apple Health - but I count on Viatom developers, they will soon rebuild the application to work with the Apple application - it is necessary !!!!!! Please do it ASAP - it will increase the popularity of O2Ring even more. I can honestly recommend the device and thank support people for quickly answering e-mails. I recommend O2Ring to my friends! Greetings Grzegorz from Poland
Thesame in polish Language:
Piszę po 2 tygodniach testowania urządzenia. Kupiłem urządzenie 10.2019 i O2Ring spełnił moje oczekiwania w 95%. Ogromnym plusem dla którego kupiłem to urządzenie jest częstotliwość pomiarów (co sekundę) i dokładność pomiarów. urządzenie nie jest duże, jest bardzo wygodne. Po minucie zapominasz, że masz go na palcu. Wibracje w mocnym trybie wybudza Cie z bezdechu - to duzy plus. Aplikacja na pierwszy rzut oka wydaje sie dosyć uboga ale po kilku pomiarach stwierdzam, że jest wystarczająca i bez zbędnych upiększeń mozna z niej korzystać. Jak dla mnie jedynym minusem jest to , że nie jest zintegrowana z Apple Health - ale liczę ze programiści Viatom , wkrótce przebudują aplikację aby współpracowała z aplikacją Apple - to jest niezbędne!!!!!! Prosze zróbcie to ASAP - zwiększę to jeszcze bardziej popularność O2Ring. Mogę szczerze polecić urządzenie oraz podziękować osobom z support za szybkie odpowiadanie na maile. Polecam moim znajomym O2Ring. Pozdrawiam Grzegorz z Polski
Gregg F.
A couple of important screens in the app won't scroll. Another complaint from someone else months ago hasn't initiated a fix. Also, I'm baffled by the thin stretch material at the base of the ring band. It looks like a manufacturing mistake or as though it's supposed to be removed or cut before using. Like they ran out of development money and had to just go with it. And what makes it even more surprising is that the rest of the design is beautiful. It looks and feels and operates as expected and feels refined with nice craftsmanship.
I was recently 30% blinded in one eye from sleep apnea causing NAION and this device was a perfect solution (among other things) to prevent another occurrence.
Jack L.
I use it to check for sleep apnea. Very well made product. SPO2 accurate. Vibration alert good to avoid long duration of sleep apnea. Battery is good for two days unless alert vibration is activated a lot. App is well designed easy to use and connects everytime. I do have to remember to wake up the ring to get data transferred. Sometimes difficult to swith bluetooth connection from one phone to another. Over all I am quite impressed with this O2ring.
Paula H.
This is an update of a previous one star review -- the first ring did not work but they sent me a replacement which so far is working great. Comfortable to wear, easy to download the data. As far as I can surmise there is a significant time difference from the US to the support personnel so that is why when you email them there is a >24 hr delay. I do recommend this product.
Christine S.
Could not get the App because my Android phone is not a 5.0. The O2Ring seems to be a good size and fits comfortably. I'm sorry another App was not available to set it up. I consulted with the manufacturers who referred me to the instruction sheet. Before purchasing, the buyer should be made aware that their phone might not access the App.
Cristina C.
I love that I don’t have to worry about my husband’s 02 levels and I don’t feel like a nag. I just wished the battery lasted longer. I wish I bought two to rotate them.
Armand B.
Life saving. It works as described and a full charge will last close to 24hrs.
John P.
. I bought the Wellue O2 ring device to check my oxygen desaturation levels. I had a home sleep study done and the results indicated that I had severe sleep apnea. I was very surprised to see the variability of the sleep apnea events from night to night.The ring has been very useful in helping me to better understand the apnea events and also evaluate whether sleeping positions can change the number and severity of apnea events. The ring appears to be accurate when measured against an oximeter. I particularly like being able to view the detailed values in the phone app. The ring is very convenient to use when installed on my thumb. I think the device is well worth the price.
Wayne P.
Can not talk with anyone. Told to leave Email message and some with get back via Email. Accuracies seem inconsistent with our calibrated Pulse Ox. Heat rates are same but O2Ring my be off by 3 to 5 percent. Tried of thumb and index finger and on each hand. This occurs even when sitting still. I’m not comfortable with having to wait 24 hours for any type of communication via Emails.
William H.
O2 Ring is working good so far. I
Need to use it for a while longer for a good evaluation. It's wonderful so far.
Larry C.
I am on a CPAP and I fought with the VA for 2 years to get supplemental Oxygen at Night. I was finally sent to an outside provider and he said he had quite a few clients that did not quite fulfill Medicare or the VA's protocol for length of time at 88% to get them to cover it; but with a little Oxygen they were doing remarkably better. I told him I was past the point of talking to the VA and said I was willing to pay for it myself to alleviate my morning headaches! I told him that I had a Hospital SPo2 Meter to monitor the oxygen saturation levels. So, he wrote a prescription for the Oxygen!
I have a Hospital type Rainbow 7 SPo2 system, but I could not turn off the audible alarm, since it is a hospital system. So I bought the Wellue Oxygen Monitor Ring and it is fantastic! It vibrates when the resetable thresholds are exceeded.
I wear the Wellue ring at night to get and record oxygen saturation data / levels. Then I write a note on that day's data form, and save as a PDF onto a memory stick. I then download the data to my Mac. Then I send data to my sleep Study Doctor, who I have been working with. The results have been as I expected and I've had the best nights sleep in years.
The Wellue ring is a blessing for me.
I do not like to recommend things to people. But, I can say it has performed as advertised & the reasons I bought it!
Andrew R.
Nice product that seems to be accurate and stable with the iOS App.
I am a bit concerned about the durability of the flexible portion of the "ring".
It seems a bit flimsy. Hopefully, it won't break!
William B.
I thought the o2 ring would give me constant readings but it didn't. Also compared to a finger tip meter it wasn't as accurate.
Steve S.
lightweight, easy to wear, easily lasts through the night. also tracks movement (and heartrate of course).
downloads via bluetooth or via usb, pretty quickly. accurate multi second intervals.
not noticeable at night. easy to use.
well done.
Stuart S.
This is a useful product. It works as advertised and buzzes me into alertness when my O2 saturation level falls below 88%. I shift position and the buzzing stops. Without these alerts, I’d get too little oxygen during sleep.
It’s also comfortable to wear, in my case, on my ring finger.
I give it four stars, not five because it gives inaccurate readings about 15% of the time. I’m ok with that. I sleep better. My life is better, and I’m glad I bought it.
Bruce B.
The 02 Ring does exactly what is advertised to do, accurately monitoring blood oxygen, pulse and motion during sleep cycles. It has been very helpful with identifying problems that occur with my sleep apnea so I can make adjustments and get a better nights sleep. Perhaps most importantly, it wakes you up when your pulse goes too low (or too high) or when your oxygen drops below safe levels. Using the app or pc software I can chart my sleep cycle for my review or to show to my doctor. I was using a fingertip oximeter for this but it was way too difficult to keep in on my finger all night and it was quite uncomfortable making it hard to sleep. The O2 Ring is very comfortable and stays in place without having to worry about it. I have been using the unit about a week now and I would rate it as 5 stars so far.
MaryAnn R.
I have Pulmonary Fibrosis. Until recently it has bee medically stable. I noticed my breathing getting a bit more difficult and on my recent visit to my pulmonologist, he found it to be active. He also put me on some very challenging meds in an effort to stop it. When I saw the Oxygen monitor that you have, I knew I needed it. I can wear it anytime, but I consistently wear it at night and I have bern gently awakened by it several times in the last ten days. I also wear it when I try to exercise or when I feel I need it. I am so glad I found it and it is much better than my occasional use of the manual oxyometer. I can’t wait to give my pulmonologist my charts. So far, I am the very happy with the results and highly recommend it.
Warren S.
Wellue Ring Pulse Oximeter:
Completely reliable. Works as advertised. Works much better than the typical fingertip oximeter. Accuracy when compared to standards was spot on. Integrated with software instantly and data presentation is excellent. Bit pricey but worth it.
Philip
Very comfortable, I forget I was wearing it. Great job showing data and things I did not realize.I really do like this O2Ring monitor. I have owned other O2 monitors, they look like a watch with a cable to the finger sensor. They are uncomfortable to wear at night which makes me not willing to wear it very often. The O2Ring if very comfortable, I forget that I am wearing it. My hands are large so I need to wear it on my ring finger or pinky. However, if it was larger, my wife would not be able to wear it. The setup instructions are very clear. I would suggest that the serial number sticker to be larger, we are an older target market. The Android App is very good, easy to use and very informative. It showed me data that I was not able to perceive before. You can use the magnify glass object, then expand the graph and or select a point and read the values at any time of the night, very well done! A very nice plus is that it monitors motion while I sleep. I can get the whole picture of my night��s sleep, thank you.
Craft
Excellent O2Ring Health Monitor.This device really helps monitor and improve your sleep health. It's very easy to wear on a finger and extremely easy to operate. Build quality is excellent. It logs your O2 level, heart rate, and movement during the night. Then in the morning you simply open the Android or Apple app and it will automatically upload the data. It presents very highly detailed O2 statistics. For example, if I hit my 12 year Scotch whiskey too hard, it shows me how destructive alcohol is on my sleep. More frequent deep O2 dips, higher night time heart rate, and much more motion. It will alarm by vibrating (user configurable) if O2 or heart rate gets too low. I showed my cardiologist the device when he asked me about sleep quality as it pertains to blood pressure and heart arrhythmia. He was very impressed. This device is well worth the money.
Scot
Useful tool for sleep monitoring!
Work great for what I use it for. I bought it to help me determine if there was a high likelihood that I have sleep apnea. I don't seem to have notable sleep apnea, but I still like little vibrator reminders for me to keep breathing throughout the night if my O2 ever drops below 92%.
Fun side note. It looks like it can also prevent your arm from falling asleep. But it only protects the arm you are wearing it on obviously.
The accuracy is a pretty close match with everything I've compared it with. However, I have often noticed ridiculously high heart rate spikes when I move. It seems like it could just be part of the way the technology works. Either way, it makes the graph look a little messy. Maybe a slight algorithm change could clean up the data. I'll update this if it ends up being accurate and random spikes are normal.
I highly recommend this ring for anyone who is wanting information about their sleep. I actually bought two of them so I can let friends borrow one so I can compare the data!
John
Easy to use. This is a great tool. Our doctor asked for the brand name and link to share with his patients who have sleep apnea. Takes seconds to sync daily with the app on our Iphone. Easy to email reports to doctor.
Jason
Very Impressed! I got this to check for sleep apnea, really a very nice product. Great App, a nice small device, battery life is good, easy & comfortable to wear, great information, rechargeable, great graphs & easy to read. I would recommend it. My one concern is I would like to see the bottom of the ring be more substantial. I worry it may break over time, hopefully not.
Tom
The sleep monitor is great! I used it for a couple of days now with no complaints or issues. Most important is the product supplement to CPAP data. The O2Ring is actually amazing and I would highly recommend it for anyone who wants to monitor their SpO2 levels and heart rate. If my SpO2 falls below a set threshold, the device will vibrate so that I subconsciously readjust my sleeping position and breathe better. This gives me the peace of mind that my blood oxygen saturation level never goes below a potentially harmful level. The Smart ring vibration sensor is flexible and should fit different finger sizes. It is the most convenient and comfortable device on the market that I know of. Battery life is as advertised or slightly better - I can get over 13 hours of monitor time on a charge.
William
This is an awesome product. It does everything it says it does and well. Amazing tool to monitor your nighttime oxygen levels and to warn you before they drop too low. I was on night time supplemental oxygen prescribed by my Dr. and now I am not because this device warns me ahead of time. Love it...It's a life saver...great customer service too. I highly recommend this product..What could be better than not having to wear that stupid cannula around your face at night if you don't have to...Buy it, you'll like it...

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
Dragon Rider
I purchased the Wellue O2Ring because I have sleep apnea and wanted something to monitor my oxygen level during bed time. During research, I found the O2 Ring stands out from the rest because of its small size. Also, it vibrates when the oxygen level dips below the configured threshold to wake you up at night so you can adjust your sleep position. This is a nice feature that a cheap oxygen monitor does not have, therefore it justifies the price point.
The ring fits on my index finger or thumb securely and does not get in the way of anything. Unlike the monitors that clip on the tip of your finger, this will not fall off. It's very compact and comfortable to wear. The unit turns on by itself when I wear it and the display shuts off automatically to save battery after a few seconds while it continues monitoring. There is a free app you can download and install on a mobile device (phone or tablet). Syncing with the app is automatic once bluetooth is enabled. I'm very impressed with the data provided by the app, it allows you to view the chart by 10h, 5h, 1h, and 30m. It also maps the O2 score over time. There is also a Windows desktop client the ring can upload data to so you can export the data to email your sleep Dr. I am quite impressed with this product and would recommend to anyone in search of a sleep monitor.
