Apps

Everything on Steam, newest first: games, DLC, demos, playtests, software, tools, soundtracks and videos. New ones appear within seconds of Steam adding them.

What is an app?

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.

We read every app on Steam continuously, so this list fills in and stays current on its own. Owners are a public estimate service's range for games and software; † marks an estimate from the app's Steam review count (about 20 to 60 owners per review), used for DLC, soundtracks and the rest.
