Let me start by saying that this app is genius! To be able to be involved in a story this way is very fun for my son, he absolutely adores it & loves to share his story "creation" with me! Please, please, please give us more stories soon! Also the story voices are static sounding and need to be fixed. This is a great start to one of the absolute best apps for kids and makes reading and story time more fun! Thank You!

I love that a child has the option of creating their own story with this app. Highlighted words are a plus as well. Anything that's gets kids interested in reading goes a long way for me. Yes the narrator has a gravely voice, but it's rich gravely and fits with the story. - App Reviewer


Great app!

Love how my daughter can change the story as it goes and that the app highlights the words as it reads. The sound is distorted now however and it sounds grainy and fuzzy. Doesn't seem to bother my daughter but I wish the
sound was back to the clear sound when we first downloaded it.
