CustomAnimator Toolbox/Speed

Ahmet Can Arslan

About this app

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

Ratings and reviews

This app is superb. Seriously, it's convenient to use. I have a little one suggestion. Please add quick toggleable tile support for the ADB command presets. If you can do that, your app will be one of the best out there. Instead of just command presets inside the app, why don't you bring it to the control center? I have an aShell You so I know how convenient it is to trigger commands on a single click.

The app is straightforward and works instantly, no complex setup required and does exactly what it says it does. The same dev also made the shizuwall app that works phenomenal so it's not surprising that they made another great app. Thanks!
