Haven't used S health properly but that maybe because I've used Runtastic Pro for the last year or so and stuck with that ( as I paid for it). Same goes with the free endomondo app that samsung gave us. I would have liked to see better integration of the heart rate monitor to your exercise session (unless I've missed something)
I want to be able to adjust the stride on the pedometer. But I do use it, and the heart rate I use some as I have 2 children that are on heart medicine.
