A new method for measuring blood pressure using a small sound measuring device that communicates wirelessly with any mobile device (i.e. smart phone). The device measures the sound of the blood flowing through an artery from any number of possible locations on a persons body. This sound measurement is then communicated wirelessly to the persons mobile device and is picked up by a downloaded mobile software application that is open to listen for the devices signal. The application then takes that sound measurement and compares it against a stored database of pre-measured sound to blood pressure measurements. The application then outputs to the user their current blood pressure measurement.
