I trust to publish such an app on their store (just to go through the process...they were giving away sweatshirts). they rejected me on the grounds of targeting kids. I'm guessing you never tried to publish this?
Nah it was just a fun project to introduce myself to the platform. I'm surprised they did that to you though. I wonder if that policy will change in the future considering there's tons of apps that target kids in their app store.
