Sponsor's own description

In this Trial we compare a new application (App) running on an iPhone (Apple inc., Model 4S) to determine systolic blood pressure (RR) and compare it to conventional oscillometric measurements using an Omron HBP-1300-E Pro device. We will include 1000 participants and perform seven repetitive blood pressure measurements (3 iPhone, 4 Omron) in each person. Primary parameter will be the absolute difference (Delta) between the correlating blood pressure measurements in mmHg.
