Do you have examples of super simple software that are intuitive for 5 yearolds?

I'm stuck on figuring out how to simplify the software product, and was wondering if the community knows of any good products to share for inspirations!

Currently we have a MVP to put together interview questions to prepare students/undergrads for their interviews. Would love to get some feedback on how to make it easier.
