Dick, I have put this request in last year "ADD PLUSE AND O2 MONITORING AND IOS 8 HEALTH APP INTERACTION" and they "Striiv" are in the planning stages of a new device that will be able to do this. It is not ready yet but it will be a compete redesign of the band to be able to do this function along with o2 monitoring. Hope to see something about this soon.
