Documentation

Use your phone as a controller for your computer, or add phone controllers to your own game. The desktop app makes your phone a gamepad, mouse and keyboard for the games already on your computer. The SDK lets a game accept phones directly, including private screens for each player.

Play

• Connect a phone: install, scan, join and reconnect.
• Controls and appearance: buttons, sticks, motion and Pro skins.
• Connection information: routes, pairing methods and measured ping.
• Five games: rules, controls and ways to win.
• Desktop controls: gamepads, mouse, keyboard and media.
• Pro and purchases: what the one-time purchase changes.
• Fix a connection: symptoms and practical checks.

Build a game

• Web game, no server: ten lines with the Controller+ relay.
• JavaScript quickstart: phones connect straight to your own server.
• Read and map input: positional controls, actions and physical gamepads.
• Wire protocol: roles, messages, limits and reconnect tickets.
• Private phone views: roles, drawing, choices and puzzles.
• Engine integrations: Godot, Unity, Unreal and native C/C++.
• Capabilities and permissions: what each client can actually provide.
• Integration guidance for coding agents: a short, concrete implementation path.

Maintain the project

• Build from source: independent repositories and available toolchains.
• Security and privacy: tokens, permissions, private data and transport.
• Source licenses: commercial SDK integration and noncommercial app reuse.
