I'm going to be honest, (as the lack of replies probably indicated) very few people will be interested in responding to something so vague. You've done the easiest task and come up with a nonspecific idea for an app; actually programming it is difficult, so before asking if anybody is interested in doing that, why not tell us what you mean by "a simple app for apple tv that responds to a certain formula"?
You're talking to a bunch of programmers who probably have interesting ideas of their own that they don't have enough time to get around to fleshing out.
