iPhone

crystl for iPhone is the companion to crystl for Mac, the desktop app that runs your AI coding agents (Claude Code, Codex, Gemini). Pair over your local network to watch shards live, read transcripts, approve tool requests, answer agent questions, and steer sessions from anywhere in the house. Requires crystl running on your Mac.

  • This app hasn’t received enough ratings or reviews to display an overview.

Send a photo and what to say about it in one message. Pick the image, type your note, and both travel to your agent together. A question from your agent stays on screen until you answer it, and your typed message is kept if a photo cannot go out yet. Prompts arrive one card at a time, oldest first, instead of competing for the same space. Tool calls in the transcript are summarised by what they acted on, and their artifacts are easier to reach.
