Keep your sideloaded iOS apps from expiring.
ReSign is a macOS menu bar app that watches your Xcode projects and automatically rebuilds and installs them to your connected iPhone before their signatures expire.
- Scans a folder for Xcode projects
- Tracks when each app was last signed
- Rebuilds and reinstalls automatically when expiry is approaching
- Lives in your menu bar — green means all good, red means something needs attention
- macOS 14+
- Xcode with a valid Apple Developer account
- iPhone connected via USB
- Open ReSign from your Applications folder
- In the menu bar, click the gear icon → set your projects folder and select your device
- ReSign will handle the rest
To trigger a manual rebuild, click Rebuild next to any project.
./build.sh
cp -R build/ReSign.app /Applications/
