# Track changes in a productivity app watchlist

**Use case:** 

Follow Todoist, TickTick and Things 3 in the US, or paste your own App Store links. The first run saves a baseline; rerun the same task to compare metadata and export HTML/CSV/JSON. $0.25 per fresh completed report, including baseline, unchanged and zero-match reports.

## About this Actor

This example demonstrates how to use [App Discovery Radar](https://apify.com/kamnev.apps/app-discovery-radar.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/kamnev.apps/app-discovery-radar.md) to learn more, explore other use cases, and run it yourself.


## 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/kamnev.apps/app-discovery-radar.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`).
