Grok-iOS – remote Grok Build from your iPhone over ACP

Grok-iOS is an open-source iOS app that allows users to remotely control Grok Build from their iPhone over ACP (Agent Client Protocol) via WebSocket, with the actual agent runtime remaining on a connected Mac. The app requires macOS with Grok CLI, an xAI API key, and iOS 17+, and functions as a remote UI pager rather than running the full agent on the phone itself.
