My Favorite Apps/Tools?Integrative Healthy Living

I recently added INSTANT HEART RATE, available for free or expanded for a small fee at the Apple App store.  This app measures your heart rate using the camera flash on certain iPhone models.  I find it helpful to have data to share with my healthcare providers and this is a tool that can be used for that. It is cheaper than a heart rate monitor, although I do have one of those.  As I understand it, one in two women will have a heart attack and the first symptom can be death.  For me, anything that gives me feedback is a tool in integrative healthy living!
