Installer Rex
11.7 MB - Initial Release:
August 2026
An offline installer app that works to allow non-rooted devices to install Phone Rex and Messages Rex as default apps.
Installer Rex is an offline, security-first Android package installer. Install APKs and split bundles, grant all requested permissions in one tap, and set apps as system defaults, all without telemetry, network access, or tracking. Powered by Shizuku for silent installs.
Tap to download the APK directly to your Android device and tap "Install" - you may need to allow unknown sources in your settings the first time.
This app is not available on Google Play
