iStethoscope Free Support Page - The World of Peter J Bentley

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.

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

On your page it says: "PLEASE NOTE: Today there is unprecedented media coverage on many radio channels, TV shows, newspapers and magazines. Because of the massive demand iStethoscope Free may be temporarily unavailable from the App Store. If this happens and you wish to try the app please check out iStethoscope Pro. Thanks for your patience!" Please explain how 'demand' for an application results in the free version being 'temporarily unavailable' when this is hosted on Apple's servers and has nothing at all to do with you. Instead of lying, why don't you come clean and admit you saw a way to make money due to the media exposure? Lying to people does not inspire confidence in your ethics.

Hi Prakash and David, the app relies on the excellent quality microphones of the iphone. Sadly many Android phones do not have microphones of sufficient quality to make it work, so an Android version would be a very frustrating experience for many.

Hi Peter This is one of the best application I have come across.. Keep the good work going and best of luck. My question is whether you are planning to modify the application to use in android phones. I currently use a android run phone. Just wondering whether you are planning to release it for android platform phones. Prakash

Hi Thomas, please see my reply below - the app continuously records and will play the last 8 seconds every time you shake or touch the stethoscope image. Please read the instructions for more details about the settings.

Intriguing app, but difficult to handle. Two questions: How do you start a new recording and dispose of an old one? Is there a way to show what all the different audio settings do and why you need them. When I leave the default settings on only clear sound produces a sound/recording. Does it have to do with the amount of fat and or muscle tissue? I would like more detail on why and how it affects the readings before I will get the payed version.

istethoscope is not available for the iPad, and it is obvious why, it's to big to place the microphones against the chest. However we know that the iPad camera accessories allow a USB mic to be connected to the iPad. This should provide wonderful opportunity to develop an attachment for the iPad, which could be used, just like a stethoscope. Imagine what the sound graphics would look like.

Hi Gary - the app continuously records so there is no need for a button. If you tap the stethoscope or shake your phone it plays back the last 8 seconds. I hope this helps! Peter.

We downloaded the free version tonight to try your application out and were totally baffled by the lack of one crucial piece of information - how to start the recording... There's all kinds of audio settings but not even a HINT that we need to tap on the stethoscope graphic to start! It would be most helpful for others if you added "Rec" or "Start" or SOMETHING on the screen to indicate it must be tapped to begin.
