I'd say you're still in the group 1. Your main goal is not the app but learning German. Therefore creating the app using AI is only a means to an end, a tool, and spending time coding it yourself is not important in this context.

The AI usage was not about learning German, but for creating an app. This would be group 2. He may use the tool he made to learn German, but using that tool isn't using AI

>using that tool isn't using AI

It is though. App is using AI underneath to generate audio snippets. That's literally its purpose

Creating those snippets don't require knowing how to make a proper recording, how to edit it down, or how to direct the voice actor for the line.
