support for special needs?

I am looking for apps web sites to help my child who is non-verbal - I found a couple of Apps I really like but want to see if anyone had some further recommendations?

 

The first AAC app I saw was MyVoice. I don't know many others, though, as my focus has been largely on finding text-to-speech apps.

 

I saw this article about an AAC patent dispute, and immediately thought of this thread. the maker of a specialized tablet (costing ten times what an iPad costs) is filing suit against the creators of an AAC app. I hope the suit fails.

But also, the article names the app, so it might be worthwhile to check the App Store for it.
