This application contains a program on the iOS platform and a sensor gadget which implements pulse reading as in Chinese medicine. Through measuring, storing and analyzing the heart pulse data, this application can give users instructive suggestions on stress management. We selected and optimized the sensor component for the sensor gadget by studying numbers of different kinds of sensors to improve the sensor precision.
