Description

iStethoscope Pro 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!

The professional version includes the ability to see and email a spectrogram of the audio, shows tips and information, 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:
- Use good quality headphones (heart sounds are often too deep to hear using the white earphones).
- 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 and a spectrogram. Press the little envelope and you can email the audio and the spectrogram image to anyone you like! Go to Settings and modify every major setting, including sample rate, audio delay, audio filters, spectrogram scaling and accelerometer update frequency.

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!


If you would like to learn how to listen and use the spectrogram to identify specific heart conditions, please check out my app iAuscultate, developed in collaboration with cardiologists.

waste of money

What a waste of money, to be able to record your heart beat you have to be on a noiseless environment, AND WHEN I SAY NOISELESS I MEAN SERIOUSLY NOISELESS, and once u can somehow (if you are lucky) then listen to some very weird noises that mixes with a hisss noise. Once you get the graphics that shows your heart beat it does not tell you any kind of info not even your heart is beating fast or slow, Do not waste your money if you are not from medical comunity or sth, I WANT MY MONEY BACK. By the way I am so angry to the people who gave 5-4 stars for this app. I have the new iphone 4, and it simply doesnt work. I dont understand how can someone give 5 stars or even 2. If I could give minus 5 i would. And to add to all even with a bose headphone it simply doesn't work. All the good reviews I believe is written by those who are selling this app. If you want to listen to your heartbeat just go to your mp. This app has no medical input on, if heart beat is healthy or not. The only thing it does is tick tick tick and a hissssssssss noise and any other noise around you. What a full of b&s. Seriously if anyone knows how to claim my 59 p, please write how to do it on your comments. Because their support doesn't work. The moment you click on the support it pushes you their homepage. Apple should know better, just DO NOT buy this. Get the free one and erase afterwards. Geeeeezzzzz

Wow - it works really well!

I bought this, not expecting much, but I don't grumble too much if my £0.59 end up wasted.

I was AMAZED when I tried it the first time and it worked really well! You can hear your own heart or anyone elses really clearly, it's not very difficult at all to find a place where the sound is pretty clear. Just stay still because it's really sensitive and picks up any other tiniest sounds.

I did/do have a couple of issues. First, it doesn't work with my bluetooth headphones. Not sure why. Works perfectly with normal wired headphones. Like others, I didn't use Apple supplied headphones, instead I used good quality other headphones.

Another issue is that I emailed myself the cardiogram jpg file and the sound, and neither are any good. :( The cardiogram is super-low res, and the sound file doesn't work, in either Windows Media Player, Quicktime, or iTunes.

I'll still give it 5 stars, for the originality of the idea and also execution, athough it's not without flaws - but I hope this will be fixed.

Works perfect

Read the instructions on the website.
1) go to ur DEVICE settings and activate (includes risk disclaimer)
2) plug in ur NON IPHONE / HANDSFREE headphones
3) launch the app AND WAIT 5 SECONDS for it to load
4) put the microphone (bottom left or right of phone) over your heart
5) press the mode button TO TAKE IT OFF MUTE.
It will then real time play whatever it's hearing (heartbeat / digestive gurgling / flatulence)
Repeat pressing the mode button will scroll thru the various audio filters as u listen.
When u go to the cardiogram screen it will play THE LAST 8 SECONDS THAT U HAVE JUST RECORDED! moving it somewhere else will continue to play the RECORDED cardiogram ! U need to switch back to the first screen to listen real time again !
