Pi Relay is a companion iPhone app for the Pi coding agent. It lets you connect securely to your own Pi remote-control server, browse active projects and sessions, and continue conversations from your phone. Pairing is simple: install the Pi remote-control extension on the machine running Pi, open the pairing QR code, and scan it with Pi Relay. Once paired, you can switch between remotes, view project sessions, read conversation history, send new prompts, abort running work, and request context compaction with /compact. Pi Relay is designed for users who already run Pi on their own computer or development environment and want a lightweight mobile companion for monitoring and continuing work away from the desktop. Key features: - QR-code pairing with your Pi remote-control server - Remote list with quick switching and unpairing - Project and session browsing - Conversation view with selectable and copyable messages - Runtime status and context usage display - Prompt sending, abort support, and /compact support - Live session updates while the app is active Pi Relay requires a running Pi remote-control extension/server. The extension is available at: https://github.com/zerray/pi-remote-control
