@mandaaleexo thanks

There is an app for iPhone called shell. It's free and it worked for me.

@dawnrose thanks I will look into it now

I got mine from amazon. Wusic, easy to use and found heartbeat right away. comes with two earphones so 2 people can listen at a time, and you can record the heart beat to a computer. I loved it and 100% satisfied

can you send me pic and price pls. thanks in advance

I ordered mine from toys r us! Works great and very clear!
