EMAY Sleep Oxygen Monitor with Built-in Recording Capability | Track Continuous Blood Oxygen Levels & Pulse Rate Overnight | Provides Sleep Report & Raw Data

As both a hardware and software developer, I have to give credit to the manufacturer: this device just works, and it does so intuitively and reliably. It avoids the modern bloat that seems to infect so many consumer products. By that, I mean hardware and software packed with unnecessary features that are not needed, not wanted, or do not work well in the first place. This oximeter strips away the nonsense and focuses on functionality, and I appreciate that. You put it on your finger, press a button, and go to sleep. It is that easy. In the morning, you open the app, press connect, and it immediately transfers the data from the oximeter to your phone over Bluetooth. The app was quick and easy to install, and it is still available on the App Store even for my ancient iPhone 8. From there, the graph is easy to understand and export. My only real complaint is that I wish the graph supported pinch-to-zoom. I emailed the manufacturer with that suggestion. Right now, reviewing the previous night’s data requires scrolling minute by minute through the entire night. A simple pinch-to-zoom feature, like in Apple Maps or Google Maps, would make scanning the data much easier. Other than that nitpick, this is a great product. Used alongside my CPAP machine, it is helping me manage my sleep apnea and improve my quality of life. For $60, it is a steal.

This little device has been working so well! My husband has some health issues that cause his O2 saturation to drop. The alarm at 88% and below is loud enough to be heard in the room or the room next door, but not too loud that it wakes the whole house. The quality seems good - it runs low on him but normal on everyone else in the family when we check, so it seems to be reliable. It is portable, comfortable, and he wears it when watching TV, sitting at his desk, and even when walking on the treadmill. The reports that are generated are fantastic. We have even downloaded some and uploaded them via his patient portal to his primary care provider. I am really pleased with the monitor and the accompanying app!

I'm very pleased with this device. I researched several at price points between about $60 to $250. This was the cheapest one of those I compared. I decided to try it before going up in price. The setup was quick and easy. Started it at 11pm right before bed assuming I'd get annoyed and wait till morning when I had more energy and brain power, but it was refreshingly easy to get going. The finger grip is comfortable. I replaced another oximeter of the same style but that didn't record and this one was noticeably more comfortable the instant I put it on. I don't need the extra strap, this stays on just fine by itself. After 9 hours of sleep there is just slight discomfort on my finger pad from having it squeezed all night. The next day, the downloading of the data and obtaining of reports was just as quick and easy as the set up the night before. As I use the app and device I am pleasantly surprised by features that are both user friendly and also handy additions. For example, a quick press of the front button will rotate the display so depending on how you tend to hold your hand you can quickly rotate the readout to see it easier rather than having to contort your hand. It just seems like they actually put quite a bit of thought into all aspects of using this. The report is a handy one page summary of the recorded events. You can even add your own notes to the recording which is really handy when it comes to testing and tracking sleep methods that may improve or worsen your events. You can change the oxygen and pulse thresholds to suit your known physical condition. For example if you expect your oxygen to be between a certain high and low, you can set that, and you can set it to alert you at the low. The default low is at 88%. You can turn the alarm on or off. You can add users which I can see being handy if someone else in the house starts having issues. This is already here, ready to go, and the new user can be added without muddying up the data of the original user. My only complaint is I wish this unit were a usb rechargeable one. The gobbling up of batteries will be annoying. I bought a quality brand recharger with batteries and am hoping that will make this more sustainable and I won't have to be forever buying batteries. But, that did add 30 bucks to the cost of this unit. They do provide 4 disposable batteries with the initial unit which helps. My first pair of the disposable batteries, after one full night of recording, still shows full power, so it'll be interesting to see how many nights they last. Overall I'm very pleased with this unit so far. The ease of use (which is so ridiculously uncommon in tech these days) and quality of reports for such a low price point option makes this unit a definite winner. I'm glad I tried this route first before the $200 options and I'd definitely recommend it for someone wanting to track their oxygen and pulse at night.

Update 5/1/20: Adjusting my rating to 4 stars after more use. This device has been incredibly helpful in tracking improvements or declines in O2 sats through the night. My research into Covid 19 has revealed possible mechanisms for the oxygen starvation that occurs in Covid 19. This O2 starvation seems to mimic that found with high altitude sickness. This led me to focus on certain supplements, one of which I was already using and have a good deal of experience with as a NAD+ repleter. As a result of my findings, I decided to add a new supplement. This one was created to help increase O2 sats in higher altitudes (wish I had known there was such a thing on a recent trip to Santa Fe). I was already running in the low 90's during the day, sometimes dipping into the 80's, and didn't have a real clue what was happening at night. I used this device to establish a good night time baseline, then added the new supplement - AltitudeRX. I have been able to track a steady increase in my O2 sats at night with this monitor, both in the gradually inceasing amount of time staying over the SpO2 threshold and in the detail the actual graphing provides. I am very impressed with this device, the app and the data it gives me. I highly recommend it. The only reason this is not receiving a 5 star rating is because of a short coming in the design of this device. Unlike a regular pulse oximeter, this one only functions if memory is available. This pulse oximeter has a 40 hour memory, and once it is full, you can no longer use it in any capacity until you empty the memory. However, to empty the memory, you must use the app. If you don't have a device with the app available, and you run out of memory, this little guy doesn't do anything. It doesn't even continue letting you see real time readings even though it can't record. I can't see a good reason for crippling its most basic functionality like that. It seems to me it should be a very simple thing to allow it to continue displaying measurements even though they can't be recorded. There also could be built into this the ability to overwrite the oldest data if someone is unable to download in time. IMHO a device like this should always be able to operate as a simple, basic pulse oximeter regardless of memory constraints. This should be a pulse oximeter first and always, and a recording device second. Original review: I have only used this for a few days/nights and would normally give this more time before writing a review, but I have to say, as a retired RN with critical care background, I am thoroughly impressed. This device is easy to use, has a nice, easy to read display, and is generally comfortable to wear. Besides the first pairing taking a few attempts, the only issues I have run into so far have been: 1) the first night when I used it on my index finger, my finger rolled enough to where it could no longer pick up a reading after a couple hours, and 2) when I tried it on my thumb, after an hour it was putting my thumb to sleep. I then tried it on my middle finger and had no issues. It recorded my pulse and SpO2 throughout the night without any difficulty. The app is intuitive, streamlined, east to use and quickly connects to my oximeter and downloads the data. The graph is easy to access and read; and creating a pdf of a report complete with graph and stats is simply done with a click of an icon at the top of the report. I have used other medical devices for BP and EKG monitoring which connect their respective devices to my phone, and I have to say this has been, by far, the easiest to use.

REVIEW OF EMAY PULSE OXIMETER I was so pleased to find a reasonably priced nocturnal O2 saturation/heart rate monitor that is accurate! I needed to verify that my CPAP machine with the current pressure settings was keeping my oxygen level >90% during my sleep, & my EMAY PULSE OXIMETER verified that! It also monitors continuously through the night, not in just short bursts as well as records all the data & can transmit that to my pulmonologist! It’s also small & easily attaches to my finger & I am unaware of it during the night. Pam K.

Im disappointed in this oximeter. This is the third one I've purchased from EMAY. The first one I bought was in 2021 I believe and it was amazing. It was plug in chargeable which is a huge Plus, this one requires batteries that you have to change out every few days. The first one I bought also had an alarm for both oxygen and pulse rate. But most of all, it is alarming how this model that I just bought is not accurate at all. The first time I used it I had it on for about an hour and it said that my oxygen was at 100% the whole time. I know this is not true because I have diagnosed problems with my oxygen and what's called primary apnea( not obstructive) so if I lay down even to just lay there and relax with out sleeping my oxygen levels go below 90 and even into the low 80s. I compared the two and I tested this out with my handy dandy oxyimeter that was giving to me by a nurse when I was in the hospital after a major car accident. And you can see from the picture that the difference is huge. 5 to 6 point difference is not acceptable in an oximeter. If your O2 is in the '90s all the time, that's not that big of a deal but when your oxygen gets down into the '80s that's a huge deal. There is a big difference between your oxygen levels being at 88 when you're asleep and 82. I do have an oxygen concentrator that I use and wear when I sleep, but I like to wear the oximeter when I'm taking a nap so I don't have to turn the machine on. I'm just disappointed because this used to be such a good brand and now it's just trash. The left is the EMAY, and the right is the Reli on brand, which doesn't have an alarm otherwise I would use that one. I also want to point out that when I was reading through the fine print it states that this is not for medical use. It's for aviation and something else I forgot but anyone can read it and find it. I find this ridiculous because an oximeter is for medical use.

What other reviewers said is true - it fits tight, and is definitely annoying when you go to bed. I felt like my pinkie was in a clamshell and the clam didn't want to let go. Very uncomfortable. BUT, read on... About the Retrofit: Looking for a solution, I rolled up two very small bandaids into little "bandaid cigars" and inserted one on each side of my inserted finger (alongside my finger) which provided a slight (very slight) "opening" of the clamshell to support my finger. When I did this, it worked well for comfort, I did not feel like my finger was squeezed an a clamshell all night long, and the device still recorded my data even with the retrofit keeping it just a tiny bit less tight. The key here is to insert a little extra padding on the white edge where the "clam" closes -- vs. a lot of bulk -- just a hint of extra padding so your finger isn't squeezed so tightly. If you opt to ry this, just make sure it's still recording data (look for the blinking light). If it's not, you've payed it open too far and it's not picking up a reading. About Keeping it on all night: It fell off once during each of the 2 nights I used it (I reconnected it when I woke during the night - then it continued recording data). So far I have not used the velcro strap designed to help keep it on - haven't found that necessary - I don't move that much during sleep. Finger choice: My physician friends told me any finger works for reading your data, so the choice is yours. I put it on my left pinkie since I'm right-handed and it's convenient to have a hand free during the night. Connecting & Reporting to the App: Setting up the app was super easy. Not entirely sure how to make sense of the report it spits out into the App, but the data looks clean and the graphics are pretty simple, so I'm sure I'll figure that out. Batteries: It's an energy eater - you need to replace the batteries (2 AAA) every 3 nights or so. I use rechargeable, so it's no biggie. Rechargeable batteries and chargers have come down a lot in price the past decade or so, so it's the way to go. Rechargeable batteries require special recycling, so don't throw them in the regular trash give them to your local recycling center. So far, happy with the purchase. It's nice to have a pulse ox that records data.

For around $60, this works surprisingly well. It’s easy to use, comfortable to wear, and gives useful overnight sleep and oxygen data. Great value for the price.

Works really well, with the little strap it stays in my finger all night. The PDF report from the app had good summary including the SpO2 graph and pulse Data can be exported with a second granularity as CSV and spo2 files for thos who wants to analyze the raw data. It will store the data in the sensor so no need to keep it synced with th phone, that is done in the morning when you wake up.

Semplice da utilizzare, di buona fattura. Buona anche la app a supporto.

I was getting weird readings on my Apple Watch of low SP02 at times during the night. This only records a snapshot every hour or so, so I got this pulse oximeter so I could actually see what was happening. It's easy to set up and use out of the box. It takes 2 AAA batteries and using a decent brand, I get about 10 nights use of this. It stays on securely with the strap overnight and it's very easy to synch it straight to the app in the morning and will hold 40 hours of recording, but synching it every morning clears the memory on the device and transfers everything safely to the phone. The reports are very detailed, you get a summary graph and a second by second breakdown of readings that you can export to excel. It does have an alarm on it that you can set to trigger at a level you choose, it comes preset at 88%. It is loud enough to wake you, most of the time. In a really deep sleep you might not hear it, or at least not register that you have. This has proven that my watch was indeed picking up low readings. I have been able to generate reports that show my sleep with the alarm both on and off and it does seem to indicate the alarm does mostly wake me before it drops too low. The hardest part of all this is actually getting a doctor to take a look at it, thankfully I have private cover and was able to send a selection of reports over and then call them to discuss and get the appropriate next steps started. This device could save your life. I had no reason to think there were any issues with my sleep, so I have to give the Apple Watch some credit for at least for making me aware, but this pulse oximeter gives you the hard evidence you need to show someone when something is off. Well worth the purchase price I feel.

This is a quality product; it is well-made and its functionality is impressive. The Android app which you can install via the Play Store works fine on my Samsung Galaxy Note 20 Ultra 5G and has a well-designed, easy-to-use user interface. The device clamps on a finger like the ones nurses use in hospitals and clinics. It samples SpO2 (blood oxygen level) and pulse rate each second and can store these measurements overnight while you sleep. I simply left the device on my index finger overnight in bed. A roll of black bandage is supplied but I ended up taking it off as the device stayed on my finger all night without it. The red LED light that shines through the finger did not trouble me as it is not bright, and the display itself turns off after 90 seconds anyway. The end knuckle of my index finger was a little sore the next morning where the device had been clamped on my finger, but nothing serious. Although the device has data storage capability, it can be used as a normal pulse oximeter for spot checks as well. To look at it has the appearance of a standard pulse oximeter, albeit the quality of manufacture and materials is noticeably better than a cheap standard pulse oximeter I already have. The device uses two AAA batteries. Four batteries are supplied in the box, as well as a lanyard, a little storage bag for the device, and a user manual. The user manual explains well how to use the device, and there is an e-mail address to contact the manufacturer if you have any questions or problems. I e-mailed the manufacturer with a query and they replied quickly and were helpful. The user manual estimates that a pair of AAA batteries should last for at least three 8-hour measurement periods. It is possible to view, save and e-mail a detailed PDF report showing statistics and graphs of the blood oxygen levels and pulse rates over the measurement period you have had the device on a finger. The report is impressive and looks very professional, and I would not have a problem showing it to a doctor. In my case I was worried that my blood oxygen level was dropping too low while I slept, but the report put my mind to rest. It is also possible to save or share a CSV (comma-separated values) file which you can import into a spreadsheet if you want to examine or analyse the data yourself. The only things that I found that could be improved are: a) sometimes deleting the data stored on the device took a few attempts; b) the user manuals that can be viewed in the app could do with being zoom-able, as the text displayed on a smartphone is tiny (a printed user manual is supplied as well in any case); c) I could not find a way of deleting a user. I do not consider these significant problems, though. Overall I am very impressed with this device.

The function and the app where fantastic. I was impressed by the quality and accuracy of the reporting. It looks like a fully professional sleep analysis. My respiratory doctor was very impressed by the report and it got me out of having to do a hospital sleep study every year. Amazing buy!
