About this app
Model Communicator (MoCo) is a free, robust AAC app designed by Kara Cotter, MS CCC-SLP and Jim Tyler, MS. CTO. Keep an eye out for additional grid sizes, vocabulary updates, and new features coming soon. FEATURES - Robust vocabulary set with even mix of core and fringe vocabulary - Topic-based organization includes specific nouns, verbs, and adjectives all within the same folders - Consistent placement of core vocabulary throughout each topic folder to preserve motor planning - Synonym suggestions and grammatical forms available across the system PRIVATE BY DESIGN MoCo runs fully offline. No analytics, no tracking, and no account. The camera and microphone are used only by the editing tools, when you add a photo or record a sound for a tile, and that content stays on the iPad. Free, from Model Communicator LLC. Made by Jim Tyler and Kara Cotter.
