How it works
appstore-screenshot-fetcher
When your agent uses it
Fetch the screenshots an app has published on its Apple App Store listing, at full resolution and for every device size (iPhone 6.9"/6.5"/6.3", iPhone Duo foldable inner and outer displays, iPad, Apple Watch, Mac, Apple TV, Vision Pro). Use this whenever someone wants to download, inspect, compare or audit another app's (or their own) App Store screenshots, check whether a listing has iPhone Duo or a particular device size, do competitor or ASO research on store screenshots, or scan many apps for which sizes they've uploaded, even when they only paste an apps.apple.com link or name an app. Not for designing or generating new marketing screenshots.

# App Store screenshot fetcher
Get the real, full-resolution screenshots from any public App Store listing, grouped by
device size, including iPhone Duo.
## Why this approach
The obvious sources come up short:
- The **iTunes Lookup API** (`itunes.apple.com/lookup`), which most GitHub scrapers use
(for example `facundoolano/app-store-scraper`), returns one iPhone set and one iPad set at
low resolution, and never iPhone Duo.
- The **apps.apple.com web page** shows only one iPhone size, and its code doesn't know about
Duo, so Duo shots never appear there.Skills included
