Answer
Lots of them
Ideally you should be looking to build a team to help you accomplish everything that needs to be done.
Are you a techie? A Creative? Have a business background?
What sort of app is it? A game, business or utility app?
The key areas that apply to all apps though are Business, Marketing, UI/Creative and of course tech. Then depending on the app specific skills may also be required. Game development or industry expertise
