PocketScroll - Foundry Mobile App Companion

PocketScroll brings Foundry VTT to your pocket. The PocketScroll Foundry Companion module is a lightweight, zero-dependency module that runs inside your Foundry VTT server and acts as a real-time communication bridge between the Foundry VTT game world and the PocketScroll mobile app (available on iOS and Android).

Once installed and activated, the module listens for requests from connected mobile devices and executes privileged operations on their behalf — rolling dice, updating character sheets, managing combat, moving tokens, and more. It also monitors Foundry's hook system and pushes live updates to all connected devices whenever game state changes, so every player's phone stays perfectly in sync with the table.

No separate backend or server infrastructure is required. The module communicates directly through Foundry VTT's built-in Socket.IO server using the module.pocketscroll-socket channel.

Get the mobile app: IOS / Android

How It Works

1. GM installs the module in Foundry VTT via the manifest URL (takes under a minute)
2. GM activates the module in their world's module settings
3. Players download the PocketScroll app on iOS or Android
4. GM shares an invite link — players tap it to connect for free
5. Play — character sheets, dice rolls, combat, and maps all work in real time from mobile devices

The module requires the GM to be logged into Foundry VTT for the bridge to be active. All privileged operations (actor updates, combat management, token movement) are executed through the GM's session with full Foundry permission enforcement.
