Khan Academy Amazon app

Hello, I've seen it posted a few years ago but I am curious if there are any plans to have the Khan Academy app to be made for the Amazon store in the near future? My kids have mostly outgrown the Kids app & get easily distracted by having to navigate through the website, which makes an app much more accessible to them. While I can sideload the app on the parent profile on our Fire Tablets, they cannot be added to the children's profiles. 

Thank you.
