I love it for what it is, but not being able to run it with heart monitoring to check my HR as i go, I tend to not use it as the HR interests me more.

Thanks for your feedback, this is a great idea! I added this feature in v2.0, released today. It now displays your current heart rate on the main pacing screen.
