This is the official support page for iStethoscope Free, the new free version of the highly popular iStethoscope Pro program. It has all the same audio capabilities and settings as the Pro version; the difference is that it has adverts and it does not have the spectrogram display.
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.
iStethoscope is hugely configurable, allowing you to change every major setting in the program. Please provide your favourite settings as comments below, to help other users. There is already extensive support available on the iStethoscope Pro page so if you have a problem the solution may be there already. If you still have difficulties, then please read the help pages and comments first. If you can't find a solution, then leave a query below and I'll reply on this page within a day or 3. If you enjoy this application, please check out the popular science book: The Undercover Scientist
