My search is over!
After reading literally dozens of reviews across many different supplier's sites I settled on this pulse-oximiter as it looked like a reasonable compromise of price and functionality. I don't have unlimited funds, so the 'high end' offerings simply were not justifiable. The very cheapest ones didn't have recording facilities which is a 'must have' for me - see below.It arrived with Amazon's customary promptness and good customer service. It was unboxed and instructions read, though it turned out to be very intuitive in use.The only part I didn't fully understand was how to 'attach' it to the app, but it became obvious once the app was downloaded to my Android powered mobile phone, as the first thing it asks is whether you want to add a sensor. I happily dabbed on the one it found (there were no others in range) and everything from there on in worked perfectly. I was sitting in sofa position 'A' when I took my first recorded ten minute reading (see pic). When I took the pulsimeter off my finger it stopped recording and stored it. I used the 'share' function to send it to my email account as a .jpg file, which I then reduced by 30% in Microsoft Picture Manager to add to this review.I'm very happy so far, and will be trying it overnight to see if it records a night time's worth of readings which I can then show to my doctor as there's a suspicion I may have un-diagnosed sleep apnoea. This should help to find out. Very happy with this product so far.

Perfect for my needs
I bought this for monitoring my O2 and pulse post recovery from a lung injury. I wanted something that records the readings over time post activity so Bluetooth was essential. Strange thing was that when it arrived there was no mention of Bluetooth or connecting to the app on the box or instructions but I needn’t have worried. I downloaded the ViHealth app and when the sensor is on it always connects straight away and starts tracing and recoding my O2 and pulse over time. The results get stored and I push them though to the Apple Health app as well. Just had it a few days but does exactly what I want. The sensor is probably not for wearing with high movement exercise or for sleeping but is fine for taking testing readings and even while walking around etc. Really pleased with this item.

Gave me the results so my doctor finally listened!
I’d been having some sleep issues for a while and my doctor said that my Apple Watch wasn’t giving me an accurate pulse oximeter reading.Bought this product specifically because it connected and recorded directly to my phone. (Other products require a manual reading).Very easy to set up and use, my only gripe with it is that you can’t lock your phone when it’s recording data. This means 1, my battery drained quickly and 2, my phone lit up the room all night!Good product, but some improvements required to make it 5 stars.

Great product, seems accurate and has plenty of useful features.
I wasn't sure what to expect with this, but read a lot of the reviews and went for it, the price was pretty good and it comes with access to an app (although it wasn't obvious that the app had Apple Health integration).Anyway, happy to say that this oximeter is pretty good. I've compared the readings to what my Apple Watch is seeing and they were within 4% or 5% of each other.The app was extremely easy to set up. I have an iPhone 11, just installed the app, opened it and when prompted said it was OK for it to access Bluetooth. Then I turned the oximeter on, it instantly showed up in the app and a quick tap later and it was paired.Looking in the settings of the app I found an Apple Health option, I switched that on and then could see the results instantly appear in the health app. Very easy to set up and use.So far I have been very impressed, it does everything I want and more.

All good
Seems good and accurate. Compared to other devices.

Very good value - highly recommended
This is so much cheaper than other spo2 recorders and the only compromise is that the device you wear on your finger is just like the standard finger oximeter, rather than something easier to keep on while sleeping. This wasn’t a problem for me, it stayed on and recorded perfectly. It may not be for everyone though. The app is easy and you don’t have to store your data on iCloud if you prefer not to. I don’t and have the data on my phone. I can just get a screen shot or send a pdf copy if I want to keep any of it. I highly recommend this product.

Did not seem to be accurate.
Did not seem to be accurate when tested against two others, my other one and my wife's. Also the O2 reading was flashing all the time. Now whether it was because the reading was 78 I do not know but very off putting

Actually quite good
I read up on these devices - there was a US medical paper I found that looked at their precision which overall for most manufacturers wasn’t very accurate. However, this device seems to be reasonably accurate and I think would certainly give a good indication of a low reading that could be a sign of issues.Connected first time to the app and was quick and simple. No issues. Gives a graph of heart rate and blood oxygen level. Syncs seamlessly to Apple health app too on my iPhone 12 Pro. Very nice little display on the device itself so can easily be used on its own.I think it’s definitely good value.

Worth every cent
I use this oximeter for overnight measurements to see if I have sleep apnea. The readout is continuously saved on my iPhone. I paid around £30/EUR35 for this device and it is worth every penny. For that amount of money, I did not expect hospital-grade accuracy, just a reasonable indication if I should contact my doctor for further research.For overnight measurements, I wear the oximeter under a mitten so that it doesn't fall off. Even when it's on the finger, my device does not measure continuously unless it is connected to the ViHealth app. I have to open the app before I go to sleep, and then I place the phone with the display facing down since the screen is on all the time.There are several reasons that I may end up without a complete set of measurements for a night. If I wake up and go to the toilet, I may lose the Bluetooth connection, so I must ensure that the device is still connected to the app before I go back to sleep. If another app is taking over the phone, e.g. to show a notification, I imagine there is a risk that the ViHealth app loses control of the screen and then stops recording, but this hasn't happened to me yet.The oximeter fits nicely on any of my fingers but after a full night on the same finger it always hurts a bit in the morning, so I usually move it to a different finger if I wake up during the night.Of course, the results from this simple consumer device are not hospital-grade, but I think even a doctor would say that it does give an indication of how often your blood is less oxygenated. The oximeter's precision is no less than that of the spouse, relative or friend that is claiming that you have respiratory arrests, and if you sleep alone you really don't have much choice before you escalate the problem to your doctor anyway.

Durable, efficace, impeccable !
Déjà 5 ans que j'ai acheté cet oxymètre de pouls et il marche comme au premier jour.Quelques secondes au bout du doigt et j'ai ma saturation en oxygène et mon pouls.Je n'utilise pas l'application sur téléphone car j'ai juste besoin de relevés ponctuels, donc je ne me prononcerai pas sur ce point.

Geweldige saturatiemeter
Goede prijs/kwaliteit verhouding. Een aanrader om te kopen. Snelle levering. Eenvoudig in gebruik. Waarden kloppen met mijn vorige saturatiemeter en bloeddrukmeter van OMRON. Goede data uitwisseling met Apple health.
