FreeAAC is an experimental AAC Grid Application for Android devices. It comes with a vocabulary of about 2000 words, and you can add new words using your own pictures, or start your own grid from scratch.
In order to cater for a wide range of screen sizes, you may want to add / remove columns (in the options menu) to get the size of the buttons right for your device and fingers.
This App uses the Text To Speech features of Android devices, so you may need to go to Settings, then Language & Input, then Text To Speech, and turn on the text to speech option.
