iOS

iStethoscope turns your iPhone into a stethoscope, allowing you to listen to your heatbeat and see your heart waveform, or listen to other quiet sounds around you. As seen on TV around the world! iStethoscope is the free version of the popular iStethoscope Pro program, with many of the same advanced settings and options.

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.

For best results:
- Use good quality headphones to hear the heartbeats.
- 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 8 seconds and see a phonocardiograph display.

WARNING! 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!

Do not place your phone over your heart if you have a pacemaker or implanted defibrillator fitted.
