Everything on Steam, newest first: games, DLC, demos, playtests, software, tools, soundtracks and videos. New ones appear within seconds of Steam adding them.
On Steam, an app is one product: a game, a DLC, a demo, a soundtrack, a piece of software. Each has its own number (the App ID, the number in its store link), usually its own store page and community hub, and it is what shows up in your library.
You don't buy apps directly: you buy or activate a package, which unlocks one or more apps.
