Thanks for wasting 10 minutes if my busy time. Besides the fact that I don't believe you can measure blood pressure with a mobile phone (unless, perhaps using the accelerometers, plus some clever mathematics), THERE IS NO WAY TO MEASURE the blood pressure and pulse. No instructions/explanations whasoever! (I was expecting, on the opening screen, a little "how to use" text. Like "hold finger on this spot, for 20 seconds", or saying "it's all automatic, here is your pressure and pulse, now".)
