ChatterBoards AAC

The cheapest AAC app compared to others offering the same features. 
Chatterboards was professionally developed, in collaboration with Speech Therapists and end users, with the aim of providing people in need with an AAC app that doesn't cost hundreds of dollars or require monthly subscriptions.

ChatterBoards is an easy to use Augmentative and Alternative Communication (AAC) aid for people of any age who have speech or language difficulties. This can include people with autism, aphasia, apraxia, stroke, downs syndrome, or any other disability that causes the individual to have difficulties in communicating or expressing their needs.

Continually updated with new features and enhancements. All suggestions and/or requests are considered.

Full feature list:

- Create and use vocabulary boards, including multiple paged vocabularies, for forming sentences.
- Board levels. Levels provide a way to progressively build up a user's vocabulary. A limited set of words can be displayed at each level, progressively building up the number of words shown until the full board is used. Words/Tiles do not move position between boards, allowing users to remember and learn a number of words at a time without them moving.
- Create and use basic phrase boards which associate a basic full phrase/sentence to an individual button, providing quick responses or questions for basic communication needs.
