PancakeStore and WaffleStore are exploitless, jailed App Store app downgraders. Because they operate within native sandbox user privileges, they require an active baseline sideloading setup to deploy their respective tool installation utility packages (IPAs) onto your device.
To interface with Apple services, they require you to authenticate using the same active Apple ID configured on the host target hardware. ⚠️ Warning: These systems can occasionally experience functional breakages when Apple deploys sudden structural changes to their server-side mechanics.
Once a target app version has been successfully handled, the resulting downgraded apps do not require any sideloading platform signatures. They install seamlessly as native systems directly through Apple's production infrastructure, pulled straight from official, archived App Store servers. This ensures they are signed completely with Apple's official App Store distribution certificate and wrapped in custom FairPlay DRM tied explicitly to your personal Apple ID accounts.
The well known, community favorite for downgrading App Store apps. It is by a reputable dev and gets quick updates whenever Apple updates their servers.
A newer, less established fork of PancakeStore. It is very similar under the hood but adds more quality of life features.
