Freezer is an Android utility that genuinely disables installed applications at the operating system level without uninstalling them. By leveraging Shizuku for privileged access, it stops background processes and notifications to stop battery drain while keeping application data intact for instant restoration.
Technical Overview of Freezer
Consumer alternatives typically rely on temporary battery restrictions or force-stops that the operating system quickly reverses. Freezer utilizes Shizuku as a privilege bridge to execute Android's native pm disable-user API, applying the exact mechanism the OS uses to halt application execution states persistently.
Core Features of Freezer
- OS-level operation: Executes real system-level freeze and unfreeze commands via Shizuku integration.
- Safety filters: Actively blocks targeting of dangerous system components, Google services, WebViews, and authenticators.
- State persistence: Retains frozen application status across both application restarts and complete device reboots.
- Source-of-truth syncing: Automatically aligns the local user interface with the actual operating system state upon launch.
Compatibility & Quick Setup
Requires Android API 26 or newer — install the APK and grant Shizuku permissions to begin freezing applications.
Disclaimer: App icon positions will reset on your launcher after unfreezing, and Shizuku requires a manual restart after every device reboot.
