I’m thinking of getting either the ABC mouse app or Homer app for my 3 year old son. He’s really advanced and has started to try to read his books every night with me and his teachers keep telling me that he’s more advanced then most kids in his class so I want to nurture that! But I’m unsure which one to get for him. Anyone use these apps??
