I'm curious about the difference between pulse measurements taken from the finger versus the wrist. How precise is the sensor technology, light reflection, and algorithm used? How does accuracy vary when moving or with different skin tones? Overall, do you think this method is sufficient for health applications?
How reliable is a wireless pulse sensor?

Wireless pulse sensors usually give more accurate readings from finger measurements compared to wrist measurements, but does the algorithm's tolerance change when you're moving or have darker skin tones?
Thanks for bringing this up. I've heard that sensors measuring from the wrist are less accurate compared to those on the fingers. What's your take on this?
