App Store Switch

About

App Store Switch is a browser side-panel extension built to solve one pain point:
jumping between App Store regions without friction.

Whether you're comparing prices across the US, Japan, Hong Kong, and Korea stores,
hunting for region-exclusive apps, or simply browsing other markets, App Store Switch
lets you switch in a single click—no system language change, no Apple ID logout,
no manual URL editing.

[ Core Features ]

▸ One-Click Region Switching
  Covers 75+ App Store regions across North America, Asia & Pacific, Europe,
  South America, Middle East, Africa, and Oceania. Click any region card in the
  side panel to jump instantly.

▸ Smart App Detection
  When you're on an app detail page, the extension detects the current app and
  preserves its App ID across regions—landing you on the same app's page in the
  target region. Perfect for price comparison, free-promo hunting, and reading
  reviews from other markets. Falls back gracefully to the region's store home
  if the app isn't available there.

▸ Platform Switching
  Instantly switch between iPhone / iPad / Mac / Apple Watch / Apple TV.
  Optimistic UI with a smooth sliding indicator gives immediate feedback—no
  waiting for page loads.

▸ Global Region Search
  Search by Chinese name, English name, country code, or pinyin initials.
  Typing "Japan", "日本", "jp", or "rb" all find the Japan store instantly.

▸ Favorites
  Pin your most-used regions (US, JP, HK, KR…) to the top for one-click access.
  The favorites block is collapsible to keep the main list clean.

▸ Auto Language Detection
  UI automatically follows your browser language (Chinese / English).
  Every visible string is fully internationalized.

▸ Liquid Glass UI
  A Liquid Glass design system with amber-gold and misted-emerald accents,
  deep-space gradient background, and floating light blooms. Light/dark theme
  auto-switches with your system. A visual experience consistent with Apple's
  own design language.

[ Why App Store Switch? ]

· Zero config: install and use. No account login, no sensitive permissions.
· Non-intrusive: works only in the side panel. Does not modify page content,
  inject ads, or collect any data.
· High performance: first-screen render is fully synchronous; every async
  operation has a timeout guard. The panel never freezes.
· Fully offline: all region data and logic are built in. No server requests.

[ Typical Use Cases ]

1. An app is free in the US store—switch to your local store to check the price.
2. Browse Japan-exclusive games—click "Japan" in the side panel.
3. Hit a region-locked app page—switch regions to see if it's downloadable.
4. Compare prices across regions often—favorite them for one-click switching.
5. Explore Apple TV content libraries in different markets—use the platform switcher.

[ Privacy Promise ]

App Store Switch does not collect, upload, or analyze any user data.
All preferences (favorites, theme, collapsed state) are stored locally in your
browser. The extension operates only on apps.apple.com and does not read or
modify content on any other website.

No host permissions. No network requests. Fully offline.
