# Watch a competitor's Play Store rating for drops

**Use case:** 

A wave of 1-star reviews barely moves a 36-million average. This computes what new reviews actually average and alerts when they run a full star below the norm.

## Input

```json
{
  "appIds": [
    "com.spotify.music",
    "com.duolingo"
  ],
  "country": "US",
  "language": "en",
  "maxRequestsPerMinute": 30
}
```

## Output

```json
{
  "name": {
    "label": "App"
  },
  "ratingCount": {
    "label": "Ratings"
  },
  "ratingsAddedSinceLastRun": {
    "label": "New ratings"

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
