I agree and that's what's my Note 8 used to provide. As I said, some update made the mandatory a health or whatever app require an account, 2fa, and a lot of setup and personal data before it'd let me access the sensor read.
previous comment meant to out the fingeron the wrist and count the pulse by yourself, analog way.
Surely the process of using fingers to measure discrete pulses is digital.
I am pretty sure you're making a clever pun, but I would suggest the word "natural".
Ah; yes I misinterpreted that thank you. Agree that would've done the trick for pulse :)
