This is similar to the deal I posted last year when Proloquo2Go was 50% off on Autism Acceptance Day (April 2). The difference this time is that the discount will be for 3 days (April 2-4) and is for both Proloquo2Go and Proloquo4Text.
Proloquo2Go and Proloquo4Text are AAC applications that assist people to communicate if they have difficulties with speech.
Proloquo2Go is one of the best AAC applications for an iOS device (iPad/iPhone) and often recommended by speech therapists. Proloquo2Go is normally quite expensive ($400), so a 50% discount will be a significant saving. I purchased this application myself when it was discounted 50% last year.
