Very pleased!
Love this App! I use this at the gym. Its always the same HR as the treadmill. A couple weeks ago, I had some uneasiness and used this, my HR was 110, usually between 50 & 60. I went to the emergency room, and it matched the monitor exactly my entire time I was there. I will never be without this Heart Rate App. Thanks, Azumio!!
