Wubbzy’s Train Adventures shares a great tale about perseverance and ingenuity for our youngest readers. Join the band of friends as they run into all kinds of problems while on the train to the carnival. Use the app as a book with no hotspots, or with full interactivity while the story is read aloud or with just word support. In the app you'll find games, videos and coloring pages that support the text. At the end you'll find questions to use with your child to talk and think about the story. There are links unlocked in the app and we encountered a "please rate" popup. Overall, a well design app with tons of features and a nice story to read alongside your young child.
