Hi, Curt,
I have used an Omron Evolv upper arm blood pressure monitor since my triple bye-pass earlier this year.
FWIW I have found the Omron Connect application and my Samsung Galaxy Note sufficient for my needs and when talking/showing to medical staff.
I don't think anyone produces what you are looking for (I couldn't find anything like that or better than the Evolv when I was looking) but perhaps using a tablet instead of a PC may work for you.
Certainly the Evolv does everything it "says on the tin", and is - as far as checking with my doctor's, and the local hospital's readings go - as accurate as one could wish.
