Winch is a Mac app for App Store and Google Play optimization that runs on the AI plan you already pay for
Shown on HN Nov 1, Winch tracks your keywords in 175 countries, drafts and scores listing rewrites, localizes them, sorts reviews into themes and draws store art, using your own Claude Code, Codex, OpenCode, Ollama or OpenRouter setup instead of selling AI credits, with all 84 tools also exposed over MCP. It's macOS 13+ only, keeps data on your Mac, asks before anything is written to a store, and costs $69 once for the first 100 licenses (then $89) after a one-day free trial.
