There is no other app with such a flexible simulator function. It lets you add and remove abnormal sounds individually and is very helpful when teaching medical students.

The microphone seems sensitive enough. Lord knows is picking up every other sound in my body like what’s going on in my intestines and my breathing but no heart sounds. It seems like a terrific app if it picked up my sound. Why won’t it pick up my heart sound, I can feel it beating so I know it’s working. Conscious so obviously I’m getting oxygen. Even tried placing it on sternal bones and my clavicle and I still get nothing. I don’t understand how the Mike can seem to be so sensitive yet it doesn’t pick up my cardiac sounds. Maybe there’s a specific frequency range I need to adjust it too, but no instructions regarding that if that’s the case.

The microphone does remind quite sensitive, but it is able to hear the heartbeat clearly enough for monitoring. Unfortunately the recording is where all my problems start. For one, I cannot playback any recording, and if I try to edit a recording, the app crashes and the recording is deleted. I also cannot share any recordings, the file is unable to be downloaded, so it kind of defeats the entire purpose.

Something with the filter algorithm, this plays a 2 Hz click all the time, whether it’s playback, or monitoring. No adjustments seem to help. The click sounds are about double the amplitude of any signal, except a few mitral samples which cannot be heard at all over the clicks. None of my other audio apps do this. It seems like an overly aggressive audio filter that turned into 1ms square waves. Anyway, it made it completely unusable, and painful on the earpiece to even try.
