App Store optimization for the App Store and Google Play, run by your own agent
Winch is a Mac app from Joydle for App Store optimization. It tracks keywords in 175 countries on the App Store and Google Play, drafts listings in every language, generates store art in every size and manages reviews. Its agent can drive the app on screen and exposes 84 MCP tools, and it runs on AI you already pay for (Claude Code, Codex, OpenCode, Ollama or OpenRouter) rather than selling AI credits. Winch is sold as a one-time $69 lifetime license with a one-day free trial, for macOS 13+ on Apple Silicon and Intel.
