# Apps that run inside your live show

> Cya is a platform for watching movies, shows and live events together online with friends, creators and audiences, with synced playback, live video interaction and ticketing.

Cya apps live in the main window of your show. The host installs one from the Apps Center; everyone in the room, on web or mobile, takes part from their own screen with nothing to download.

## Your questions, answered

**What is a Cya app?**

A small web app that runs inside the main window of a live Cya show. Games, shared readers, 3D viewers and show tools: the host installs it once and the whole room takes part live.

**Do viewers need to install anything?**

No. Only the host installs an app. Everyone else plays or follows along in the Cya room on web or mobile.

**What do apps cost?**

Every app made by Cya is free. A third-party app shows its price on its page and in the Apps Center.

**Can I build my own app?**

Yes. Cya apps are built on a public SDK with a manifest, synced state, roles and storage. The developer docs at cya.live/developers walk through it, including a guide for building with an LLM.

**Where do installed apps show up?**

Under My Apps in every room you host. Put one in the main window from there, and control it from the Controls panel.
