We have developed 8 interactive research-based apps for children. They are based on the research-based storybooks.
For children to get the most from the interactives, they should be very familiar with the story first and have been read the story with the adult several times.
Then, they can try a few pages of the app at a time. The apps are very long, so just working through a few pages at a time work best.
To access our app interface, have a look at our 12 free storybooks and you will find the link there.
