Wellue O2Ring Oxygen Monitor - Sleep Pulse Oximeter Bluetooth Recording SpO2 and Heart Rate, Sleep Tracker with Free APP & PC Overnight Report | iF Design Award Winner

I'm an experienced user of the Wellue wristband-ring system and have been generally quite happy with its performance, but I'm pretty impressed by some of the design changes in Wellue's "02 Insight Ring." First, ease of use: the old system required attaching both the hard drive wristband (to your wrist) and then inserting the ring's chord into the wristband hard drive. The O2 Ring reduces that slightly cumbersome procedure to one step – simply slip on the ring! In other words, they've collapsed the ring and wristband into one device.This design change has more than a simplifying effect, I suspect. Perhaps more importantly, it reduces by half the wear at the critical hard drive connection. Anything that reduces the number of times you need to insert a USB-type connection is a good thing. Eventually, as anyone who works with computers knows, those kinds of connections are generally the first problem you encounter as the connection tends to grow weaker with use and usually at some point simply dies. The only connection you make now is from the O2 Ring to a charging device or your computer. I just hook it up to my computer and leave it attached to recharge from my computer, reducing the connection process further.Another design improvement is the display sensor. In the wristband-ring design, the wristband display of oxygen levels and pulse rate is motion-triggered: that is, a shake of your wrist will cause the display to light up. Not a bad thing, but that means the display is being constantly triggered as you move around at night. I'm not sure this causes wear and tear on the unit, but it surely shortens the battery life. The 02 Ring, however, isn't motion-sensitive: you need to "swipe" the ring surface to summon the display. Kind of like how you open an old Kindle. So you only see the display when you choose to.Yet another improvement I noticed was in the ring band itself. In the original wristband-ring configuration the elastic rubber ring has a tendency to wear and break at some point. In the 02 Ring model, the elastic rubber ring has been reinforced! Excellent preventative measure, in my opinion.Otherwise, the function remains the same. Just plug the O2 Ring into your computer or use a phone app (I use my computer) to get a reading on your night's sleep. It is totally compatible with the simple and nice function of the software. My computer already had the software from the wristband-ring model, and it worked perfectly with the new 02 Ring. I don't actually remember installing the software – other than that it was easy to do. The Ring's brightness, display, and other features can be adjusted to your taste (see manual). I have yet to read the manual; the Ring is so intuitive that I was able to easily use it right out of the box!Though I'm not a "medical professional," I've devoted considerable time into investigating methods of improving my health, and what's more basic to health than sleep? If you snore or wake up feeling headaches or fatigue, you owe it to yourself to monitor what your body does while you sleep. The Wellue system gives you a clear picture of your heart rate, blood oxygen levels, and motion throughout the night. It takes the guesswork out of how you slept. Large plunges in oxygen levels, for example, can spell major problems – and could lead, according to current medical lectures, to stroke and heart disease on top of just not feeling rested and ready to take on your day.I was able to greatly improve my sleep with the Wellue units when combining their information with oxygen therapy at night. For me, Wellue + oxygen concentration machine has made my nights enjoyable again, and I usually wake up feeling refreshed, my brain clear, and ready to take on the day. I wish the same for all of your who suffer from sleep issues.

Great Computer and Smartphone Apps. My doctor loved the reports.>>> Computer App:- Connects via USB cable which is supplied. Easy data upload process.- Very good app with great reports.- Reports data for: O2, heart rate, and motion.- Sleep report provides a full-night summary on page one.- With more detailed 1-hour increments on the pages that follow.- Exports to a PDF, or as raw data to a spreadsheet (.cvs)>>> Smartphone App:- Connects via Bluetooth. Easy automatic data upload process.- Data summaries and same data views, just condensed for the phone.------------NOTES:- Battery life is rated at 16 hours. So charge daily.- Device is meant to only be worn while sleeping.- Too bulky for other times of day and not durable for all-day use.- Durability: Unknown, but seems to be ok.- Due to my hand size, wearing it on my left ring-finger. It is most comfortable there.NOTE: The USB Cable works only with the Ring, and other USB Cables did not work with it. The connector is large so there may be some circuitry in it specific to the ring.--------------- What I really wanted is a smart ring to wear all of the time:1) To monitor O2 levels (sleep apnea and narcolepsy issues)2) Mainly to monitor heart rate, whereas I have developed occasional tachycardia (non-rheumatic tricuspid valve insufficiency), and wanted to track incidents during the day as well as night.Condition may only bee over-caffeination, so drinking less coffee. Has not showed up on any sleep reports, nor have I noticed having it since using the ring.---------------- ALTERNATIVES:- I tried another ring (style and brand) designed to wear 24/7 and 3-day battery life, but their phone app didn’t work, and there was no computer app, and non-existent instructions.- The other alternative is a Smart-Watch, but I was trying to avoid the bulkiness of a wrist device.------------

I wear the monitor on my thumb while sleeping. It is very comfortable. I love the way it downloads to the app, which has a lot of precise detailed information about your night. The app lets you set it up for different users, too. It was a good purchase and I am very satisfied.

I've used it for about 2 weeks now. It does what it promises, but I may decide to return it if the software keeps letting me down.It's comfortable to wear and I love the ability to set the alarm levels and the alarm vibration strength. The screen is easy to read and I like being able to check the time while using it, although it does lose a few minutes every week if you don't sync the time with the app. The battery needs to be charged daily, and while it does seem to take a while that is ok.My complaint is the lack of software maintenance. The current version of the Windows OS Insight Pro software is v1.8 and it has been two years since it was updated. After just three downloads via the included USB cable, the software no longer sees the device. I was able to get the device to talk to the Android app, but I was really hoping to just use the Windows app.Another thing that has started happening is for the alarm to start going off non-stop as soon as I put on the device, as it initially thinks I have a racing heart rate until it gets a bit of data and realizes the rate was normal all along. If that keeps happening, I may decide to return it, as that initial alarm is unnerving and chews through a bit of battery.Overall, I'm a bit torn, as I got it at a good discount and the low-O2 alarm works, helping to avoid groggy wakeups.Update 2/14: I did not return the ring and have continued to use it. The current version of the Android app works well for me, but for reasons unjustified, location MUST be enabled to sync with the ring (not just bluetooth). On the plus side, the ring has stopped alarming when I put it on.Battery life has been a bit inconsistent - I suggest recharging daily. The motion detection is pretty weak (it isn't sensitive enough to detect sleep cycles, let alone restlessness).I still think it's worthwhile and still 4/5 stars.
