The app needs more structure. Perhaps this is 20th century thinking, but there should be a course setting of some type that allows you to lock the child in to a structured progression of lessons. Leave the rest of the app as is, sometimes kids want to just play around, but you also need a course option. As the app works now, my daughter will play one part for 20 minutes, and another part for 2. I want her to have a more balanced exposure to your curriculum. Thanks.
