Show HN: Crit – Visual QA for iOS apps and AI coding agents

I built Crit, a CLI tool that lets you capture screenshots from iOS Simulator, drop pins on what's wrong, and hand structured feedback to any coding agent.

You just:

crit capture — screenshot your app screens crit serve — review in browser, click to pin bugs and add comments Tell your agent: "review .crit and fix each issue"

It saves annotated screenshots and JSON to a .crit/ folder. Works with Claude Code, Cursor, Codex, Gemini — anything that can read images. No plugins, no MCP, no dependencies.

macOS + Xcode required. Android not yet supported. Repo: https://github.com/natethegreat/crit
