About this app

KillFlux is an app killer and background process manager for Android. It uses Shizuku to force-stop apps silently, without requiring root access.

DASHBOARD
See live RAM usage, battery level, and how many apps are running in the background. Tap Quick Boost to kill all background apps in one go.

APP KILLER
View all running apps and stop them one by one or in bulk. Filter by All Apps, User Apps, or System Apps. Search by name, sort by memory, name, or last used. Add apps to a whitelist to protect them from being killed.

SCHEDULER
Create rules that automatically kill selected apps when a trigger fires. Available triggers: screen off, charger connected, charger removed, low battery, app launch, or Wi-Fi connected. Each rule can be enabled or disabled independently.

SETTINGS
• Theme: Light, Dark, or Follow System
• Color Preset: choose an accent color (Blue, Green, Orange, and more)
• Dynamic Color: uses your wallpaper colors on Android 12+
• Start on Boot: keep the service running after a reboot
• Confirm Before Killing: shows a confirmation dialog before stopping apps
• Persistent Notification: shows a status bar notification while the service is active

SHIZUKU REQUIREMENT
KillFlux requires Shizuku to function. Shizuku is a free, open-source tool available on Google Play that grants apps access to Android system APIs using ADB-level permissions no root needed. A setup guide is included in the app.
Force stop background apps and schedule auto-kills with Shizuku.
