I think Fitzy+ app ( https://www.fitzy.plus ) is a better option if the phone has HRM sensor. It can monitor heart rate, oxygen saturation, blood pressure, cardiac output and all day activities. Check : https://play.google.com/store/apps/details?id=plus.fitzy.fitzy_app&hl=en_IN
For those who are not happy with Samsung removing the sp02 tab from Samsung health with the new update (version 6.5).. You can just uninstall S Health from the phone and then download and install S health apk version 6.4, (I've included a link down below)... you will now have the sp02 tab back and the ability to measure stress separately.
I installed this app on my Note 10 and it gives an error message when i try to measure. Does not work. The only permission relevasntis the allow body sensors which I allowed.
You're correct. I have a Note 10 now. I dowloaded the Samsung Health App 6.4 from APK mirror and unchecked autoupdate, low and behold I now can toggle oxygen saturationlike I had on my previous phone.....unfortunately when you go there it says on the bottom "This phone can't measure your oxygen saturation, but you can sync your oxygen saturation data from your Samsung account with this tracker."
Not the correct solution. O2 has now been moved to stress. It tallies bpm and o2 saturation to figure stress level.
