Heart rate accuracy is pretty good. Actually, most of the sensors are. When I’m at the doctor I typically check my heart rate and blood oxygen levels on my watch against the nurse’s readings. It’s usually spot on or extremely close.

Be sure to manually activate fall detection. It isn’t on by default unless you’re 65 or older.
