In addition to assisted communication, there are iPhone apps to support ABA therapy, writing your child's Individualized Education Program (IEP), and even one for those on a gluten-free diet that catalogs the menus of all major restaurant chains (I can save you the $3.99 for this app...the roast chicken with vegetables is the only GF thing on the menu).
The iPhone has certainly revolutionized my autistic daughter's life, but not because we've purchased any of the above apps. No, we haven't purchased anything nearly that constructive, because we haven't made it past the games. For those of you who don't know, children with autism have a difficult time waiting...in line at a store checkout, for the food to come in a restaurant, in traffic to get to their destination. That's where the iPhone comes in and why the games are far and away the most useful "autism" apps there are. For just $.99 per game, I get complete peace of mind. I no longer have to scan the checkout lines looking for the least stupid cashier and making sure that I don't get behind a senior citizen with a checkbook in hand. Get a debit card already grandma!
The first game that I purchased for Audrey was a cupcake-making game. First you pick out your cupcake liner, choose the batter, put it in the oven, set the timer, and then shake your iPhone to get them out of the tin. Pretty cute. Then you pick out your toppings and decorate. Here's an example of a yummy one with candy shamrocks, chocolate bunnies, gummy bears, candy hearts, peppermints, gum drops, circus peanuts, kiwi, and bacon.
