Vital Signs Camera App

I couldn’t imagine that this app would be anywhere near accurate. I purchased it because Davis Argus (amazing physician and researcher) wrote "Really amazing app that can measure your heart rate and breathing through the iPhone or iPad camera. The camera detects subtle changes in the skin color of your face to measure your heart rate and movements of your chest to measure your breathing rate. It really works, and is accurate! You have to try it.”
So I did try it and looked at the different readings I would get if I just took my pulse and respiration rate manually, used a pulse oximeter or this program.
Vital Signs turned out to be spot on.
Cool tool for sure..
