A day with a difference is a model for how to merge a book style app with direct questions to help children master important early learning concepts. You meet two important characters, Mr. Big and Mr. Small. They need your child's help to sort and compare the different things in their homes. After a few story pages with colorful pictures and clearly spoken text, your child will be asked to choose between bigger & smaller, same & different, more & less, longer & shorter. The games are short and involve simple tapping which makes this a great app for young children.
