The fastest and the best iOS signer.
Automatic updates. Background signing. App Cloner. Zero effort.

SignOs is an iOS app that signs, installs and updates other apps on your device, the same way the App Store does it. Tap Get on any app from a repository and that's it — it downloads in the background, signs itself, installs, and shows up on your home screen.
It's built on top of the open source Feather project. SignOs is owned and developed by me, @ihateios — huge thanks to clARATION and the Feather contributors for their work, this wouldn't exist without them.

Download SignOs.ipa from Releases and sign it with SideStore,
Sideloadly, AltStore, TrollStore or SignOs itself. Every push to main builds a fresh IPA
automatically, and tagging a version publishes a release. The app can also update itself
from its own repository right on your device.
make iphoneos
That produces packages/SignOs.ipa. You need Xcode 26 or newer on macOS.
