From Carole Zangari of PrAACtical AAC, here is a list of 49 Free or Lite Versions of AAC Apps. Here are some considerations when selecting these apps.
AAC App Considerations
> Core word approach or functional language approach or visual scene approach
> Pre-made communication displays or create your own
> Sentence building options
