Presentation as iPad Application?

I am thinking of making use of iPad to show customers a dynamic presentation. Customers will have access to an iPad for it and I won't take part on it, so more than a presentation it will act like an iPad application. (internal links between screens...etc.) Which would be the best way to do it? I was thinking of using Keynote but I'm not sure if it would be the best option. Any other idea? Thanks.
