I love it when a plan comes together... and I love it when a vendor enhances their product, either based on my review, or coincidentally with my recommendations! Either way, such improvements need to be recognized. Such is the case with HeartMath and their Inner Balance Sensor for iOS.
When I reviewed the product, my only wish was for built-in support for the Lightning dock. And now that has been addressed. In addition to enhancing the connectivity options, they have added cloud support to store your data. This way you can track progress, achieve rewards, and share your data.
