Should it be looser-fitting for bedtime? Yes, but with a little retro-fitting, it works fine…
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.

Print an all night Oxygen Report Hard Copy
I bought this Bluetooth pulse oximeter (EMO-80) to monitor my Oxygen levels during night sleeping hours. It was very user friendly to operate but I had questions regarding printing the report, so I sent an e-mail to support. Very quickly a person named Nick replied with simple process to get the APP and print out the results. After that all went smoothly and I was able to print the PDF Oxygen percentage report, exactly what I needed. Compliments to this company and in particular “Nick” who has been very helpful and Prompt.Lawrence Minch

Great Little Device
I purchased this device specifically to monitor my O2 levels while I sleep at night. From time to time, I want to monitor during waking hours, as well. It does well at both, with one small caveat. I’m including the app as part of my review because I was specifically looking for something that would work well with my phone and integrate into Apple Health. This device does both.First, the device is a good size, runs on 2 AAA batteries (4 included), and is easy to use. You just install and set up the app, put it on your finger, and it does what it does. I use it on an IOS platform, and it syncs well with Apple Health. There is a limitation with Apple Health that doesn’t allow it to store as much granular data as the EMAY App does, but it’s nice to still have it in there (Apple Health only records by the minute, while the EMAY App records by the second. I prefer “by the second).Anyway, the app is easy to set up and mostly easy to navigate. It will store the data long-term, while the device will only store up to 40 hours (this is fine with me). You can run reports in the app and keep the data indefinitely. That said, I wish there was a way to back up the EMAY data into iCloud, or something, to make sure I can keep it. Still, it goes into Apple Health, which is probably good enough, and that does go to the cloud.The device itself has a display that changes depending on how it’s oriented. In other words, the display will flip, depending on which hand it’s on and how you hold up your hand. This is a cool little feature that I really like and didn’t expect to have.My one and only one small caveat to all of this is the device will not stay on my finger at night. I have really large hands, so that could be the reason why, though I’m not so sure. One night, it was on my finger for 10 minutes before it fell off, which means it probably came off right after I fell asleep. Another night, it took about an hour.Now, the device comes with some “stickum” tape (I’m not sure what it’s called, but I’ve used it for first aid. It’s a roll that of non-sticky tape that will stick to itself, but not leave a residue on the device or anywhere else. It’s kind of like a mini ace bandage, but it sticks to itself). I have tried a couple different ways to use the tape to keep the device on my finger at night. I think I figured it out, but it uses a lot of the tape, which I don’t like. Maybe I need to mess with it some more.Even with the tape, when I look at the report, there are moments when the device loses contact with my finger. One night, it stopped monitoring altogether long enough that it shut itself off. This even though it was taped to my finger.One other thing I don’t like has to do with the app. At the time of this writing, it seems like I can only run reports on one use session at a time. I can’t select a block of sessions and run a report on that. Say, I want the whole week instead of last night only. I can’t seem to do that. It also took me a minute to figure out how to view reports in landscape mode.At any rate, it’s really nice that EMAY includes the tape, four batteries, and a small fabric case in which I can keep the monitor when not in use. Another little detail, as I mentioned, is the “flip” display. I just wish there was a better way to keep the monitor on my finger at night. I’m still giving the device a 5-star review, however if I could give it 4.7, I would, just because keeping it on my finger is a challenge overnight (it’s fine when I’m awake), and the reporting function is limited to one session at a time.All in all, I’m quite happy with the purchase and am looking forward to collecting my oxygen data at night over the long term as I try to improve my health. I’m a data hound and really like how the app, combined with Apple Health, can store my data long-term, run reports, etc, so I can have something useful to look at.
Computer user –
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.

Amazon Customer –
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!

I purchased this pulse oximeter for sleep study. It was a great device and served my purpose adequately. I will buy it again if required.
Q VAN WYK –
After struggling with irregular sleep patterns, I learnt of this device and decided to give it a go in hope of understanding my sleep patterns better. It was very easy to setup, downloaded the associated EMAY app (free) and got to using it whilst sleeping. In the morning you simply open the app and connect to the Oximeter via Bluetooth where it downloads the data to the app. It’s so quick and easy! At first I couldn’t quite interpret the data, but sharing the report with my AI app, it was able to break it down for me in simple terms and tell me exactly what was going on during the night, it’s fantastic and is allowing me to build up a bigger picture that I may able to take to my doctor for further investigation. It takes time getting used to sleeping with it and it will go through batteries very quickly but very worth it. Good value for money, well built and reliable. I’m very pleased with this purchase and would recommend.
