There is no particular difference between a web "site" and a web "app", they are both very broad definitions that usually boil down to the same thing - very vanilla CRUD database operations (create, read, update, delete) behind a pretty page.
The difference between Heroku and most web hosts is what happens when your requirements increase.
With a conventional web host you will scale vertically which means at each growth milestone you move up to the next plan eg starting on a $5 basic shared plan and eventually growing up to the $10 and $20 and $50 and $100 per month plans and finally separate db and web servers.
With Heroku you design your application to scale horizontally so you add more capacity (dynos) and that capacity means you can support x% more traffic unless other bottlenecks get in the way like database load which Heroku and many of their partners also provide in scalable fashions.
