Autism spectrum disorders—a group of related neurodevelopment conditions that impair communication and social interaction—are incredibly common. According to the Centers for Disease Control and Prevention, one in every 68 American children has been diagnosed with some form of autism. With intervention (the earlier the better), many autistic children flourish. Unfortunately, early diagnosis is the exception rather than the rule. Nationwide, the average age of diagnosis is four years old.

Now, a team of researchers at Duke University has released a free app, called Autism & Beyond, to mechanize part of the autism screening process. The app is available to anyone with an iPhone who is willing to take part in a Duke study.
