3C Task Manager is a free utility and tool app developed by 3c for Android devices. It is a simple yet powerful task manager designed for everyday use. The app provides a range of features to manage running tasks on your device efficiently. The UI is highly configurable, allowing you to customize it as per your preference. You can sort running tasks by CPU, memory, or network usage and see detailed information about them. Additionally, you can add a home-screen launcher to app features, configure UI the way you like it, and pause display.

One of the most useful features of the app is the ability to stop apps on non-rooted devices using Accessibility services. The app never collects any information, ensuring your privacy is protected. You can also kill any apps or kernel processes on rooted devices and force-stop apps on rooted devices or using Accessibility services. The app also allows you to fill or stop specific apps when the screen is turned on or off or under low memory condition.
