Running Heart is a sports mp3 which can be considered your best friend while running as it is designed for runners to motivate them while running. It is featured with two modes, the first one allows the runner to have control over his pace through the central pace slider which in turn determines the next track to be played and instructs the speed and hence controls a steady pace, while the second mode uses the built in heart rate sensor to select songs depending upon the user heart rate.
