Bottom Line: When I first reviewed Mr. Shape's TouchCard, I commented on the fun involved in each interactive puzzle to help teach basic vocabulary. This review focuses on the entire content of the app with available in-app purchases. Spoiler alert: It's still a fun, interactive app for toddlers and young preschool kids, though interested parents should read on to determine if some issues are a factor. The in-app purchases all cost $1.99, each adding nine additional cards to the app.
