I haven't settled yet on a AAC (Augmentative Alternative Communication) app. The cost of these apps tends to be a little high. So I feel like it's worth researching before jumping in. I've read really good things about iCommunicate, AutisMate, and Proloquo2Go. I'll post a review once I've made a choice (I'm leaning towards iCommunicate, not because it is the best for voice production, but because it has the best social story maker that I think will work well in session.)
Without a doubt there are plenty of apps that will keep the attention of a child with special needs, however, I am looking for apps that engage a child without causing them to disengage from everything else. In other words, I am looking for apps that let a client connect with others, not shut them out. Here are a few, that other therapists really like. Furry Friend is one we already use at home and is helpful for encouraging kids to talk. Among other things, the furry monster repeats everything they say back to them. Monkey Preschool Lunchbox is a good app for younger clients that uses puzzles to teach colors, shapes, etc. Touch and Learn Emotions is a free app (love free!) with cute pictures of kids expressing a variety of emotions.
What apps have you guys loved? Let me know in the comments. I would love to hear about other useful apps for therapy.
