I'm an SLP developing Tactus Therapy Solutions apps for language therapy, and I ensure all these features are in all our apps to make sure we're moving beyond motivating paper activities. While our apps are designed for adults, they're being used with kids really successfully. Check us out if you haven't already: and keep up the great blog!
