there are heart rate apps that use the camera and they work well. I've tested vs my heart rate monitor
azumio makes one
 
Missed opportunity if you ask me.

Touch ID is a seriously pointless feature. lol
 
plus, even if they did allow third party apps access to TouchID, its too early for anyone to develop something that complex, the iPhone 5S just came out less than a week ago...and its just a fingerprint scanner, I don't think it has the ability to detect heart rate data.
