AppDowngrader

A macOS app for downgrading iOS apps to older versions. It provides a GUI for browsing installed apps on your iOS device, viewing available historical versions, and installing any previous version.

brew install rxliuli/tap/app-downgrader

Manual: Download the latest .dmg from Releases, open it, and drag AppDowngrader to Applications.

First Run: macOS Keychain Prompt

On first use, macOS may show a system dialog asking to allow ipatool to access your Keychain:

"ipatool wants to use your confidential information stored in your keychain. To allow this, enter the \"login\" keychain password."

This is normal and safe:

• The password it asks for is your Mac login (user account) password — not your Apple ID password.
• It is macOS asking permission for ipatool to securely read the Apple ID credentials stored in your Keychain, so you don't have to type them every time.
• Select Always Allow so you only see it once. If you pick Allow, macOS may ask again on the next operation — simply pick Always Allow.

Build from Source

# Run in development
swift run

Limitations

• Some apps may fail to list versions due to Apple API restrictions
• Paid apps require a prior purchase on the same Apple ID
• Apple may change or restrict the APIs this tool depends on
