First rate for your heart rate!

I have used this app for over three years. I used to use both this and a manual check but the app has stayed so consistently accurate that I dont bother with the manual check anymore. There is one feature which you can have on or off and its a beeping sound to correlate with your heart beat as you check it. I choose to toggle this feature off. Great app!
