# Watch competitor apps daily for new versions and price changes

**Use case:** 

Watches Spotify, Duolingo and Notion on the App Store and Google Play and returns one row per change since the last run: a new version with its release notes, a price or in-app price move, a rating shift past 0.1 stars, a title or description edit, a developer, category, size or installs change. The first run records the baseline; run it daily. $0.0006 per app checked plus $0.002 per change.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/insight.solutions/app-store-monitor.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
