wonderful app! – PrepositionBuilder™ Review

This app has been wonderful for my 2 children. My son is 4 and has autism. He struggles with using correct preposition and this app is helping him learn them. I have noticed, though, that some of the pictures/questions seem a little too advanced or complex for his age group. I do wish the app could be divided into age groups. I know that's hard for kids on the spectrum...their skill level is rarely at the same typical peer level but some guidelines for at least preschool age and elementary age would be helpful.
