Character Sheet Hangout

I need an Android app. I already have a design for it, I just need it to be built. I have many documents that I want a comprehensive app to go through them while maintaining the ability to change text fields that link to other values like sums on excel. This app is for a character sheet plus more for a role playing game. I have are and the format layouts with a design and they way it should function. And if it does well I would like to add more features later on, like messenger integration, allowing them to view characters they are chatting with. Able to be a modual for a Gamemaster app(work in progress).
