If I were to make a mobile app it would have to be a very creative game. You would run your own store and you would choose what you want to sell. It could be a bakery, a clothing store, anything you can think of. And here's the best part...you get to make whatever you sell! So if I made a clothing store, I would design my own clothes. I would also make the app free so it is fun for all! Waddle On CP!
