Keeps getting better By far the best app/attachment I've used so far. My little one from Amazon is good, but can't record or give more reliable statistics and information, like iOximeter can. If you have problems, or don't get the " high level ear level warning" when you plug the iOximeter into the phone jack, check your phones ear plug jack for oxidation or build up. Works fine on my Samsung and my wife's iPhone. I use mine while riding my road bike to maximize my workout. 100% flawless :-)
No Recording / History The Android app is very basic. While offering graphical display of pulse rate and SpO2, it does not save and report on previous sessions. The graphs are cumbersome to navigate, do not sync timelines, and are missing perfusion index and breathing rate statistics. While acceptable for real-time reporting, it offers little value for any use case requiring historical data.
Very sorry it did not work First unit arrived and was not working. Just as others reported no power, no red light that ever came on. Tried on both galaxy S5 & iPhone. So I ordered a second one, giving it the benefit of the doubt, the second unit isn't working either :(
I have an S3 Samsung. I use it for a sleep study to monitor low oxygen. I transfer the data to Excel for analysis. Logs data every second.
Doesnt work No power to device using headphone jack on both my android phone or android tablet.
Very buggy The application gives up and stops working after an hour or two. This makes it of very limited use for monitoring sleep.
