Note: This app replaces the Heartbuds app by Heartbuds LLC. Do not download the Heartbuds app.
The Heartbuds App provides the ability to listen, display, and record sounds simultaneously using an external microphone. The recordings can be played back or shared. It is intended to be used with the Heartbuds device -- an acoustic amplifier -- and your own headphones or earbuds to record even subtle sounds. The Heartbuds device is sold separately and is available at www.heartbuds.com.
This version adds improved audio noise filtering, software filtering emulating a stethoscope, and an estimated heart rate display.
