CustomAnimator Toolbox/Speed

Take full control of the settings Android hides — no root required.

Custom Animator started as an animation speed tweaker and grew into a complete Android tuning toolbox. Adjust animation scales, change display density, flip developer options, automate app behavior, and boost performance — all from one clean interface.

🎬 Animation & Display

• Adjust Window, Transition and Animator scales — any value, not just the 0.5x / 1x / 1.5x steps

• Slider Mode for quick changes, Manual Input Mode for exact values

• Save presets and switch between profiles in one tap

• Built-in animation comparison view to preview the difference

• DPI Changer — adjust display density (with a Shizuku fallback for OEMs that block it)

• Smallest Width (dp) presets you can save and restore

🛠 Developer Tools

• Toggle ADB debugging (USB / wireless), "Don't Keep Activities" and "Limit Background Processes" without digging through Settings

• Extra tweaks: disable keyboard animations, show seconds in the status bar clock, force screen rotation

• Graphics API Override — run any app on ANGLE or the native driver

• Built-in terminal with saved command presets

⚡ Automation & Performance

• Auto Force-Stop — automatically force-stops selected apps the moment they go to the background

• Auto Permission Disabler — revokes permissions of selected apps in the background and restores them when you reopen them

• Compile Booster — runs AOT compilation across installed apps for faster launches, with live progress

🔐 Permission requirement

To change system settings, Android requires:

android.permission.WRITE_SECURE_SETTINGS

Grant it once, either way:

• Shizuku (recommended) — the app requests and grants it automatically

• ADB — a single command, shown inside the app

Background features ask for usage access and notification permissions only when you turn them on.

🧩 Perfect for

• Speeding up UI responsiveness on any device

• Testing apps at different animation scales and densities

• Building custom performance and daily-use profiles

• Power users, developers, testers, and tinkerers
