So, I've spent the past year developing a 27 page interactive story book for kids 9-11 and recently published it to Google Play for Android and am waiting on Apple to approve it (or deny it for random reason X to be fixed and resubmitted while I wait another week or more for their next reason, etc) but, I really want to get the word out on the book as it's a story of a young robot engineer that grew up without his father and sets out on an adventure to rescue him. You build one of two robots and there are mini games and the story is inspired from real events in my own life. There are messages about bullying, etc. I think its great. The illustrations are AAA and I want to market this app. Is there any way some of you may know of that will allow you guys to market the app on your sites while earning a cut of the sales from it? Are there programs or anything that set up such a thing?
