Concerned

I am kinda curious, I purchased the app and tried it and I heard what I thought was my babys heartbeat however we tried it on someone (who isnt pregnant) it had the same sound as if they had a babies heartbeat. Has anyone else experienced that? I really hope I didnt waste my money on a app that doesnt work. And, sounds like it works.
