# Dekadans

> Dekadans is an App Store keyword rank tracker and ASO (App Store Optimization) research tool for iOS developers. It tracks where an app ranks for each keyword every day, with popularity and difficulty scores, across all 175 App Store storefronts and separately on iPhone, iPad, Mac, Apple TV and Apple Vision Pro. Every feature is also available to AI assistants through a hosted MCP server.

Key facts:

- Free plan: 1 app, 10 tracked keywords refreshed daily, 25 research calls a month, 7-day rank history, MCP access. No credit card.
- Pro plan: $6.99/month or $59.99/year, with a 7-day free trial: unlimited apps, tracked keywords and research calls (fair use), full rank history. Payments via Polar.
- Apple App Store only; Google Play is not supported.
- MCP server: Streamable HTTP at https://dekadans.net/mcp, authenticated with a bearer API key created in the dashboard. Works with Claude Code, Codex, Cursor and other MCP clients.
