Great book, one of my daughter's most requested apps. The games and interactions are all cute and great. Would be 5 stars except for the freakishly long and hard airplane game in the middle. You can't tell preschoolers that there's a reward and then make it that obnoxious to get to.Other than that it's a fantastic app- just asked daughter what her favorite page was and she said "every page, all of the pages! Everyone should get Cozmo" so there ya go...

After reading this I felt the need to write a positive review to outweigh the negative ones I read. The app has been developed well, it is clean and easy to use. There is original artwork and several interactive areas on each page of the book along with appropriate sound at good volumes. There are a number of settings available so the app can be adjusted to your appropriate age as well as read along text, incorporated games and other fun additions for kids to play with. I only wanted the story to be longer!

I first downloaded Cosmos about 5 years ago or more, for my grandson when he was very small. He loved it, as did I. He played with it until my granddaughter downloaded it and began playing it a couple years ago. She is now 4 and still loves it. Please keep adding to the story, it’s one of our family favorites!

With so many iOS updates, this App has produced none, and the sound no longer plays. The App is completely muute, no music, no narration, no effects, just images. Pretty pathetic for a paid App.
