App Review Radar — App Store & Play Store Alerts (Vigia)

Monitor iOS App Store and Google Play reviews for your app or competitors. Alerts only on new, actionable reviews: 1-star complaints, urgent issues, and review-volume spikes (bad-release / review-bombing). One unified Apple+Google feed. Charges per alert, never a monthly flat fee.

What it does

Unify Apple + Google reviews and get a bad-release / review-bombing spike alert. You get only what changed since your last check — never a full re-dump to diff yourself.

Why Vigia — 5 advantages a raw scraper can't match

1. You pay the alert price only for real change. New-app review alerts are billed only for genuinely new app reviews since your last check. A quiet run bills just the small source-check fee (the cost of looking) — never the alert price on unchanged data. Raw scrapers bill every row of a full re-scan every run.
2. Never billed on a failed source. The source check is charged only when the source actually responded. If it's down, you don't pay for our outage.
3. Append-only delta + spike signal. The first monitored run stores a free baseline; later runs deliver only what's new, plus a velocity-spike alert when volume suddenly surges (trend / review-bomb / hiring-surge).
4. Hard cost cap you control. Set maxTotalChargeUsd and the run can never bill above it — predictable spend, no surprise invoice.
5. Agent-ready output. Clean, normalized rows and a RUN_SUMMARY.json with ready-to-use signals — chainable from any MCP / A2A agent in one step.

Example input

{
  "appStoreApps": [
    "389801252",
    "com.spotify.music"
  ],
  "monitorEnabled": true,
  "maxTotalChargeUsd": 1.0
}

Set monitorEnabled: true so the first run stores a free baseline and later runs return only new results. Pin a monitorId to keep separate targets from sharing state.

Output

Each row is a normalized change record: record_id, subject_id, rating, severity, topic, actionable, signals, why_it_matters, text. A RUN_SUMMARY.json accompanies every run with the aggregated signal (counts, velocity spikes, trend).

How you're charged

• App review alert — billed once per new app review since the last check (this is the only charge that scales with change).
• Source check ($0.03) — billed once per monitored target per run, only when the source responded. A failed source is free.
• A quiet run bills only the source check ($0.03), never the alert price. Vigia never scrapes the source itself; it chains a licensed scraper, caps every call, and passes you only the delta.
