Question regarding schema markup for product reviews

[jackheadsets]

Hi there,

I found a wordpress app that allows you to fetch Amazon reviews and show as a rich snippet in google (link below). I want to know of any similar shopify apps that allow you to do the same thing. Please let me know what my options are.
