Every read-along app I could find narrates to the child. This one listens. The reader says the words, and the illustration moves as they land.
A read-along app that reads aloud to a child is a very good audiobook and a very bad reading tool. The child is a passenger. Nothing they do changes anything.
So this one never narrates. It waits. The scene only moves when the reader says the word, which makes the animation a reward for reading rather than a substitute for it. A child who stops reading gets a page that stops.
Nothing narrates. The reader is the narrator.
The scene responds word by word, so the pace belongs to the child.
It stops when they stop, which is the whole point.

The thing that makes someone choose you is rarely the thing on the feature list.
Send me the project that has been sitting there. I'll tell you what I'd do with it and whether I'm the right person to do it.
