description: When the user wants to analyze their own app's actual performance data from App Store Connect — real downloads, revenue, IAP, subscriptions, trials, or country breakdowns synced via Appeeky Connect. Use when the user asks about "my downloads", "my revenue", "how is my app performing", "ASC data", "sales and trends", "my subscription numbers", "App Store Connect metrics", or wants to compare periods or top markets.

# ASC Metrics

You analyze the user's **official App Store Connect data** synced into Appeeky — exact downloads, revenue, IAP, subscriptions, and trials. This is first-party data, not estimates.

## Prerequisites

- Appeeky account with ASC connected (Settings → Integrations → App Store Connect)
- Indie plan or higher (2 credits per request)
- Data syncs nightly; up to 90 days of history available

If ASC is not connected, prompt the user to connect it at [appeeky.com/settings](https://appeeky.com) and return.

## Initial Assessment

1. Check for `app-marketing-context.md` — read it for app context
2. Ask: **What do you want to analyze?** (downloads, revenue, subscriptions, country breakdown, trend comparison)
3. Ask: **Which time period?** (default: last 30 days)
4. Ask: **Specific app or all apps?**

## Fetching Data

### Step 1 — List available apps

```bash
GET /v1/connect/metrics/apps
```

Match the user's app to an `app_apple_id` if not already known.

### Step 2 — Get overview (portfolio)

```bash
GET /v1/connect/metrics?from=YYYY-MM-DD&to=YYYY-MM-DD
```

### Step 3 — Get app detail (single app)

```bash
GET /v1/connect/metrics/apps/:appId?from=YYYY-MM-DD&to=YYYY-MM-DD
```

Response includes: `daily[]`, `countries[]`, `totals`.

## Analysis Frameworks

### Period-over-Period Comparison

Fetch two equal-length windows and compare:

| Metric | Prior Period | Current Period | Change |
|--------|-------------|----------------|--------|
| Downloads | [N] | [N] | [+/-X%] |
| Revenue | $[N] | $[N] | [+/-X%] |
| Subscriptions | [N] | [N] | [+/-X%] |
| Trials | [N] | [N] | [+/-X%] |
| Trial → Sub Rate | [X]% | [X]% | [+/-X pp] |

**What to look for:**
- Downloads rising but revenue flat → pricing or paywall issue
- Trials rising but conversions flat → paywall or onboarding issue
- Revenue rising but downloads flat → good monetization improvement

### Daily Trend Analysis

From `daily[]`, identify:
- **Spikes** — Did a feature, update, or press trigger them?
- **Drops** — Correlate with app updates, seasonality, or algorithm changes
- **Trend direction** — 7-day moving average vs prior 7 days

### Country Breakdown

Sort `countries[]` by downloads and revenue:
1. **Top 5 by downloads** — Are you investing in ASO for these markets?
2. **Top 5 by revenue** — Higher ARPD (avg revenue per download) = prioritize ASO
3. **High downloads, low revenue** — Markets with weak monetization
4. **Low downloads, high revenue** — Under-tapped premium markets (localize)

### Revenue Quality Check

Compute from the data:

| Metric | Formula | Benchmark |
|--------|---------|-----------|
| ARPD | Revenue / Downloads | > $0.05 good; > $0.20 excellent |
| Trial rate | Trials / Downloads | > 20% means strong paywall reach |
| Sub conversion | Subscriptions / Trials | > 25% is strong |
| Revenue per sub | Revenue / Subscriptions | Depends on pricing |

### Trend Alert

When a significant change (>20%) is detected, flag it:

```
⚠️  Downloads dropped [X]% this week
    Possible causes: [list 2-3 hypotheses]
    Next steps: [specific diagnostic actions]
```

## Common Questions

**"Why did my downloads drop?"**
1. Pull daily trend — when did it start?
2. Check if an update shipped on that date
3. Check keyword rankings (use `keyword-research` skill)
4. Check competitor activity (use `competitor-analysis` skill)

**"Which countries should I localize for?"**
Pull country breakdown → sort by downloads → flag high-download, non-English markets → use `localization` skill

**"Is my monetization improving?"**
Compare trial rate and trial→sub rate period over period → use `monetization-strategy` skill for paywall improvements
