Knock Knock Family is an interactive peek-a-boo game that helps toddlers (ages 1-4 years) learn faces, sounds, shapes, gestures, and simple words. Personalize the game by creating your own visitors from photo albums or simply taking new snapshots from within the app. You can even customize the game by giving a name and a voice greeting to each visitor. In addition, each visitor is paired with an everyday object for the embedded shape-matching puzzle.

In play mode, when the door knocks, your toddler can try to guess who’s behind the door by peering through the cutouts in the door. When your toddler taps or swipes the door, the door swings open and the player is greeted with a recorded voice greeting. The game uses Apple’s face recognition technology. If a face is detected, the paired puzzle will be placed in the appropriate region. For example, a crown puzzle is placed on top of the head, and a cookie puzzle is placed beneath the mouth.

Too busy to personalize the game right away? No worries! Knock Knock Family comes preinstalled with six sample family members (Mom, Dad, Grandma, Grandpa, Little Girl, Little Boy), five animal characters, and five free empty slots. Fill the empty slots with family members, friends, pets, and even favorite toys. Knock Knock Family is ideal as a toddler's first app because it is fun and easy. Older siblings can get involved too by helping to personalize the empty slots!

Great app

My almost 2 year old loves this app. It worked out that I downloaded this app around a time we were seeing our son's grandparents, aunts and uncles. It was easy to add family members on and for them to even include their voices. After the first night of checking it out, he was saying "uncle Matt!" I highly recommend this app for those with kids who don't get to see their relatives as often as we'd like :)

Great App

Great app that you can load your own family members for the familiar game of knock knock. The 1st time my 2 year old niece played it she was intrigued that her family members were behind the door! Even the family dog 😊

Kids enjoy this over and over. Great feature of personalizing voice and people. Simple but a good learning task for cause and effect, greeting and focusing on people.
