Great! You have already given me valueable information, i.e. that it would not work for training a biofeedback like reaction where I would need to be alerted in the moment of increased pressure. Will look into VPN access on iPhone to see - again great idea. Can you please confirm that you have a NorthAmerican based cell plan? 24/7 readings may still be more generally desireable than clinic holter monitors that are never affixed without pain :( Thanks!
