Easy to use communication app for a nonverbal child

My autistic nonverbal son has been using this app for over a year now and its worked out great. He started with PECs when he was 2, then in kindergarten he moved to the iPad with Proloquo2go. The app is very user friendly. There are a lot of training videos on the website and a helpful staff to answer any questions and provide additional resources. The other reviewer, Mom of 4 kids, had an issue with the Options button visibility. I think this is an IOS9 issue, to bring back the toggle to show and hide Options all you have to do is exit the Settings app from multitasking, hope this helps.
