In WP Store, what does "With live tile" mean?

Either I don't know what it means or they leave this for every app.

Many of the apps I have installed with a "live tile" don't do anything when pinned to the start screen.

I have pinned this tile to the start screen and nothing happens. Same thing with Here maps, drive and transit.

Just wondering if I have a misconception of what the term "Live tile" means.
