I had heard rumors of being able to monitor blood pressure with the iphone 6. But, since it's debut, I haven't heard anything. Is there some new device you need buy to do this? I didn't hear mention of the apple watch being able to do this. I know there are some current devices available that are expensive and don't have the best reviews. Considering just buying a dedicated device that has a good price and reviews without iphone connectivity if there is nothing new with the 6.
