The link above is a story from USA Today about the creator of the Verbal Victor iPad app. I have not had a chance to see the app in action but it seems like a great AAC app option for use with kids who are considered emerging or beginning communicators. I also like the $6.99 price point because it is significantly lower than some of the other AAC apps available. The app uses real pictures of objects and also is reported to allow for easy addition of your own pictures.
This app looks like a great, budget friendly resource for kids that may not be ready for more advanced AAC apps like Proloquo2Go or Look2Learn.
