This app may not be what you expect...
I made the mistake of being misled into thinking that this application would actually take your blood pressure with your iPhone much the same way that other apps record your heartbeat with your iPhone. It only seems to serve as a journal for the information that you put into it. It does provide a good record for the fields that it offers. For me it was a waste of money as I was expecting that it would actually take my blood pressure.
