[QUOTE="MacInWin, post: 1863821, member: 396914"] The error range for all pulse oximeters is in the +/- 2-3% range. So you can have a 4-6% variation between the finger clamp and the iPhone, easy. I even see variations on my finger pulse oximeter of 5-6% if I just change fingers. And it's not consistent what finger is higher. So the watch is close, which is all it needs to be, really. It's similar to the EKG reading. It is an approximation and there to show gross variations, not precise measures. [/QUOTE]
