just a tip for everyone from an iOS developer... Don't waste your money on apps claiming they can hear your baby's heart beat. They can't. unless there is a special attachment for your phone there is no technological way it could work, neither iPhone nor android has that technology internally. Apps like these include baby heartbeat (iPhone) fetal Doppler (android) to name a couple. just want to save someone from spending unnecessary money on these useless apps! :)
