Q: Does every App that I create for clients, come with its own mobile website as well?
A: Not necessarily, most Apps are just web Apps with a range of different features that you have added to them. But each App can be a mobile website if that's wants you want to create! You are totally in control of which features you provide in the Apps you make. They can be simple or more complex with menus, forms and pages, its up to you.
When we talk about using an App as a Mobile Website we usually mean creating a multi-page App with a menu system to replace a mobile version of a website. You do this by setting up your domain to point to the App you have created so this is displayed on mobile devices. This can provide a more attractive and responsive alternative to many standard mobile versions of websites.
