iStethoscope Pro turns your iPhone into a stethoscope, allowing you to listen to your (or your baby's) heatbeat and see your heart waveform, or listen to other quiet sounds around you. As seen on TV around the world!
The professional version includes the ability to see a spectrogram of the audio, email the sound in different formats, live audio filter control and has no adverts.
Please note that this app is intended to be used for entertainment purposes and as a demonstration of the technology. It is not intended to be used for the diagnosis of disease or other conditions, or the cure, mitigation, treatment, or prevention of disease and should not be used as a medical device. We are working to develop fully certified iPhone apps that may be used as medical devices in the future.
Developed in collaboration with cardiologist researchers. Used by cardiologists for research on heart disease as described in the Journal of Medical Devices. For best results:
- Press the microphone in the bottom of an iphone to your chest. A good place is the apex of your heart (below your left nipple).
- Place the microphone directly against the skin, not through a shirt.
- Take the iphone out of its protective case if you use one.
With practise you should be able to find a wonderful clear sound. Shake the iphone to hear the last 9 seconds. Press the share button and you can email the audio to anyone you like! Press the left arrow to see the filter window and change the low pass filter as you record. Go to Settings and modify the amplifier gain or initial filter settings.
WARNING! It takes time to learn how to listen to your heart. You may need to watch the youtube videos. Don't give up! If you are patient, this app will help you to learn the necessary skills. It takes physicians years to learn how to use stethoscopes correctly and the iphone microphone is smaller than a conventional stethoscope diaphragm. You cannot place the microphone randomly and expect to hear your heart - you must place it very accurately. To hear your heart you must learn where to listen!

What's new in version 10.01
App now always asks for permission to use the microphone when first installed.
