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.
