Asspp

Asspp is a powerful client designed for users who need to manage multiple Apple IDs across different countries and regions. Switch stores instantly, download apps from anywhere, and manage your IPA library—all without logging out of your device.

• 🌍 Multi-Region Access: Browse and search the US, Japan, China, or any other App Store region seamlessly. No more switching system accounts just to check an app.
• 👥 Multi-Account Support: Add unlimited Apple IDs. Asspp automatically uses the correct account for the store you are browsing.
• 📦 IPA Management: Download official, signed IPAs directly from Apple’s servers for backup or sideloading.
• ⏪ History Versions: Need an older version of an app? Asspp makes it easy to find and download previous releases.
• 📱 Cross-Platform: Native experience on both iOS and macOS.

• iOS: iOS 17.0 or later.
• macOS: macOS 15.0 or later.
• Apple ID: Required to communicate with App Store APIs.

Asspp utilizes the same underlying communication protocol as ipatool. According to community speculation (unverified), previous outages of this protocol were likely caused by:

1. Widespread usage triggering Apple’s risk control mechanisms.
2. Protocol modifications following the patching of an iCloud security vulnerability.
3. Adjustments to Apple’s front-end gateways, which now enforce stricter traffic allocation and request validation.

Given the increasingly strict management of these APIs, if the protocol becomes invalid again in the future, this project may not be able to provide further fixes.

⚠️ Important Security Warnings:

1. Protect your GUID: Please treat your device GUID as a highly sensitive password. Never share or leak it to anyone.
2. Do NOT use your primary Apple ID: We strongly advise using a secondary or burner account with this tool. If your account is banned by Apple, it could potentially result in an unremovable Activation Lock on your device (while there are no confirmed cases of this happening yet, we cannot make any guarantees).
