Download iStethoscope »

iStethoscope turns your iPhone into a stethoscope, allowing you to listen to your heatbeat and see your heartrate, or listen to other quiet sounds around you. Wearing your earphones, lightly press the inline microphone to the pulse in your neck and hear your heart beating clearly! With a little practise you should be able to find a nice clear sound – when you do, iStethoscope will tell you your current heart rate. Alternatively, press the microphone against a flat surface to hear a pin drop. Look out for the undercover scientist who appears with an interesting fact every now and again.

If you’d like to see how easy it is to listen to your heart using this program, watch this:
(Or just go to and search for "istethoscope")

Please note that this app needs the microphone in order to listen, so it will not work for ipod touch, only iphones. Please check the website for more information! If you’d like to help me make the app better, please get in touch and give me details of specific things to be improved in a new release.

If you enjoyed this app, please check out the popular science book, "The Undercover Scientist" by Peter J. Bentley available in a bookstore near you.
