The Autism 5 Point Scale EPA, developed by the Autism Society of Minnesota in conjunction with the Minnesota Department of Human Services, is a handy, simple, free app that featuring a visual 5 point scale and strategies suited for student use. It seemed to be missing for a short period from the App Store but is again available.
Check out more information on the app here: http://wp.me/p1w0d0-Ci
This is in my OT iTool Kit as well as on student dedicated iDevices!
