The Early Literacy Skills Builder app incorporates systematic instruction to teach both print and phonemic awareness.

Full levels can be purchased from the in-app store. Five years of solid research have been completed through the University of North Carolina at Charlotte, proving ELSB to be a highly effective literacy program and more effective than a sight-word only program.
