I have the 6s! It works I wish I could show you.. If you give me your number I can text you the recording of the heartbeat so you can hear what it sounds like before you download it

@babykarter,

What kind of phone do you have? I have a iPhone 6+ and I wanna make sure I'm not wasting money on a app that won't work

The one I have costed 4.99 but it's well worth it, it's called Baby Beat.. And I can even record his heartbeat and share it

I did , & anytime I get worried or start thinking something is wrong I use it and I can hear my baby's heartbeat so clearly!!! I love it bc it eases my mind when I start thinking something is wrong!!!

I haven't, not sure I would mess with it..
