Get BuzzBack Cause & Effect With Vibrations & Sound on the App Store. See screenshots and ratings, and read customer reviews.
This looks like a great sensory cause and effect app! Looking forward to trying it.
Update (11-10-12) – After trialing this after posting (not a particularly good idea…) a bit more explanation about this app. Created by a teacher specifically for students with auditory and visual impairment it is best suited for use on an iPhone which has vibration capabilities, not a feature of the iPad. Developed by Touch Autism, creator of Touch Trainer app, BuzzBack provides specific cause effect for low incidence students with dual sensory impairment. If not an app that you might use, pass it along to teacher or parents of individuals with multiple handicaps!
