Primal Feed aggregates blog feeds from sites that support the primal lifestyle, and presents the latest information on paleo-oriented nutrition and high-intensity exercise, organized chronologically. Any of the content can be commented on or shared by email or on the popular social-networking sites. The current blog feeds are those from "Mark's Daily Apple", "Paleo for Women", "Paleoista", "The Paleo Solution", and "The Paleo Network". Any of the feeds can be turned on or off individually from the menu on the opening screen. The app is free and supported by ads.
