FST — Augmentative and Alternative Communication
FST is an offline augmentative and alternative communication (AAC) app: boards, visual routines, messages read aloud.
It helps people with speech or language difficulties — autism, aphasia, temporary disability in a medical setting — express themselves, and gives caregivers what they need to adapt it to each person: labels, pictures, routines, themes. This manual covers all of it, screen by screen.
FST works 100% offline. Your data stays on your device; no internet connection is required.
