This site has been put together to be the definitive collection of AAC (Alternative & Augmentative Communication) Apps for the iPod, iPhone & iPad. Why do this when the appstore already exists? Well simply put its not exactly easy to find these things! Its also nice to have an overview of what the developers mean when they write hyperbole such as "the Ultimate communication app!" from a more independent source.
The site has been together as a result of a talk at BETT 2011, by Will Wade, an Occupational Therapist at the ACE Centre, Oxford. You can take a look at this presentation and a rather lengthy, but comprehensive view of the iPod, iPhone & iPad for communication here. Although initially created by Will you are invited to add, and keep the list up-to-date and fresh.
