My favorite heart rate monitor application.
Biggest Fannnnnnnnn??
It seems to be the most accurate out of the the other two I tried. Also, it has a workout option that is pretty fun. Would recommend.
Amazingly Accurate

I compared the app with the heart monitor in the ER- accurate within one beat/min. Very pleased and I was able to the ER doc what my heart rate was in the the hour before I went to the ER - helpful to docs, and ultimately helpful to me. Thanks!
