AssistiveWare announces Proloquo2Go 5.3, an important update to their symbol-supported communication app for iOS devices. Proloquo2Go gives a voice to those who cannot speak. It is used by people with autism, Down syndrome, cerebral palsy and other diagnoses for everyday communication and language development. The latest update to include Dutch comes after a year of research on Dutch and Flemish core words, grammar and language development. Proloquo2Go 5.3 is $249.99 and can be downloaded from iTunes.
