The Compass app is created by Tobii Dynavox, the industry leader in helping connect lives through communication. This version of Compass includes the premium PODD pageset. PODD, created by speech pathologist Gayle Porter, is a way of organizing whole word and symbol vocabulary to provide immersion and modeling as well as a means to express a range of messages in a variety of environments. There are PODD Pagesets to provide multiple options to suit the communication and language requirements of different individuals. Compass provides a voice for individuals who cannot use their natural voice to participate in their everyday lives.
