I was wrongly diagnosed with sleep apnea. I was looking for something that records and produces data overnight because the sleep equipment was providing no benefit and degrading my sleep. This device was exactly what I needed.
For quick checks, you can use the onboard display. It shows a live pulse trace, the oxygen level, and pulse rate. It is bright clear and easy to read. The values track well with my fitness watch, and if they are a little different, this is the one I trust. This is what you get with any SPO2 sensor.
If you want to get data recorded over the course of the day, or in my case overnight, this seems to be unique in the price range. As far as I can tell, all other devices under $180 require your phone to be running and recording continuously while you are gathering data. This device records its data internally for up to 40 hours and you turn on the app only to download and print or store the data.
Being able to share the data is why the app needs access to your files. It allows you to generate a well formatted, detailed, summary report save and it as a PDF. You can share it with you heath care provider, or in you records if you want. This is a legitimate reason for access. It is not so China can look at your pictures. Logically it is pretty safe. You can set the app to have access when running, and you only need it open to sync the data and look at or export it then shut it off. The other similar model have the app open the whole time you are recording and give a much larger window for mischief. The company states and I believe, that there is no data taken from you phone and stored on a server somewhere. The data is yours alone unless you decide to send it somewhere.
The app is clean and simple. It lets you select a session from a list, organized by date and duration. Then you can scroll through your data on a second by second basis. It displays a graph with accurate with adjustable thresholds clearly shown on the scale, and with the values of the second at the red vertical line shown as text at the top of the screen.
Another thing that some may want to nerd out over is that you can export the raw data in CSV format. It saves three data fields, the sample time, the SpO2, and the heart rate, for every second during the recording so you can import and analyze it in anyway you want.
The battery life seems to be good, probably aided by the fact that it does not need to maintain a Bluetooth connection when you are recording data.
This is a device and app that was developed by smart technical people to provide clear accurate data, in about as useful form as I can imagine. I mean that as a pretty big compliment.

Simple to use and gives a good picture when used overnight. The grip tape that comes with it is a great help. Put the oximeter on your ring, loosely put the tape lengthwise down the bottom of your finger and around the bottom half of the oximeter. Back up your finger and around the area between the oximeter and your hand. Repeat this 2 or 3 times and cut off the reusable tape. Works a treat and is hardly noticed as you sleep. This is a great package at a good price. I would highly recommend it.

I am happy to report that the Oximeter is working extremely well.
I elected for your product specifically because it can record readings continuously rather than most meters which only show a measurement at a specific moment in time.
I should explain that I suffer from Obstructive Sleep Apnoea and use a CPAP machine overnight. I had
suspected for some time that once I was asleep my breathing became very shallow and thus my O2 stats
dropped and the fact that I could record this and more download it and send it to my consultant has been most helpful. I am waiting for my next appointment at Leicester when we can discuss the findings and plan accordingly.
The only slight issue I have encountered is that sometimes during sleep the normal movement of your
hands can cause the meter to move just enough so that it thinks you have taken it off and the readings stop, possibly an on/off switch that you need to actually switch off rather than an “auto off” would solve this but it is a minor issue.

It’s lovely to have something as straightforward as this is that does what it says it does. Without pinching tightly or being uncomfortable it stays in place and working all night including trips to the toilet. I suggest you think carefully about which hand is less needed for whatever you might want to do before you plan on taking it off. The hand with it on can still be used as support to help the unencumbered hand. My only minor criticism is that the extremely long record on the app measures time from when it started running. I would like it to say the clock time so that I can see what was happening at a certain time. It only takes a couple of seconds for a reading to appear on the screen so is also useful to get a spot reading.

Sleep apnea can go undetected for years, while silently destroying your health. It increases your risk for obesity, heart disease, stroke, and dementia, among other things.
I have several people in my family with sleep apnea. This device gave me an easy, low cost way to check on how our heart rate and oxygen level are doing while we sleep.
You just turn it on, put your finger in it, and go to sleep. In the morning, it is easy to connect the device to your phone to download the readings. Then, you just scan through the readings. If your levels drop too low, you will know you need to follow up with your doctor.
It works well, and couldn’t be simpler to use.

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.

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.
