The new iOS application allows us to record the heart sounds from up to 5 minutes from the past. This new technology is based on the same principles of TiVO and other DVR. TiVO is the device used as a digital video recorder. If we open this Heard application once, it constantly records the surrounding audio into an ephemeral, self-destructing buffer and saves only if we insist to save it.

We can also save and share the recorded audio directly into our Facebook or E-mail accounts.
