Hi, I'm an MD looking to get software that looks at Heart Rate
Variability.  I know of 2 products:

1. Freeze Framer 2.0 by Heartmath (www.heartmath.org)
2. NervExpress (www.nervexpress.com)

I'm looking to see if any practitioners have had experience with either
of these products to see which one would work better for an MD looking
to get into biofeedback therapy for anxiety.

In talking to customer service representatives, I had a really bad
experience with someone at NervExpress and was not impressed by his
explanation.

thanks,
Laura
