Auto-Pause Android Bouncer That Freezes Apps the Second You Background Them, Without Root
Power users want a one-tap, no-root tool that immediately suspends every backgrounded app's network and CPU activity unless the user explicitly whitelists it, then auto-unfreezes when reopened. Existing freezers (Hail, Ice Box) require manual freezing and Shizuku reactivation on every reboot, and OEM 'aggressive battery saver' breaks legit apps without protecting from the bad ones. The market is asking for the freezer Greenify used to be, rebuilt for Android 14/15 reality.
The non-obvious insight: ship it with Dhizuku-based device-owner activation so users don't even need a PC for ADB once. Greenify's death and the dontkillmyapp.com mess have created a generation of Android users who blame Google for what is actually fixable at the package-suspend layer.

The freezer category exists but is stuck in 2018 patterns of one-time root or Shizuku setup followed by manual per-app actions. Nobody ships a 'freeze on background, thaw on foreground, allowlist explicit exceptions' default behavior even though it's now possible without root via Shizuku-via-Dhizuku.
