This is awesome because its truly accurate.

This is a great app. I love it!
Works perfect for what I need.
Tried way too many times to get my heart rate. Kept stopping at "8secs left". Meanwhile, there are a ton of these apps that work perfectly. Not worth my time and CERTAINLY not worth a dime for upgrade. Look thru the store.. You'll find much better apps for free.
