About this app

A simple task manager for everyday use

In-app purchase can be made to remove ads and unlock features (see below).

This app uses Accessibility services to help you stop apps on non-rooted devices, but will never ever collect any information.

Highly Configurable UI allows you to transform the app into something you really like

Highly Configurable Widgets are all resizable, from a simple gauge to more complex data display and historical graphics.

★ Sort by CPU, memory or network usage.
★ Add home-screen launcher to apps features.
★ Configure UI the way you like it (dark/light, button themes, text size, etc...).
★ See detailed information about running tasks.
★ Pause display.
★ Show system data in widgets (1x1 text and gauge are freely customizable)
★ Kill any apps or kernel processes on rooted devices.
★ Force-stop apps on rooted devices or using Accessibility services.
★ Fill or stop specific apps when screen's turned on or off or under low memory condition.

If rooted or Android lower than Marshmallow (6.0), app can also:
★ View and sort by memory used
★ View kernel processes

3C Companion app (non-rooted users) available here.

If Xposed framework is installed, app can also:
★ Set permanently the Linux's niceness of any process

★ Exploring task's data directory requires root and 3C Explorer (free app).
★ Viewing task's logs requires root and 3C Logs (free app)

NB:
★ Killing doesn't prevent apps from restarting.
★ Some apps are immune to force-stop and will restart anyway. You need the crystallize feature of 3C Toolbox Pro to prevent them from running.

Use in-app purchases to unlock the following features:
★ Remove Ads
★ Advanced UI theming options
★ Automatic auto-kill/stop
★ Add shortcut to notification
★ Enable extra widgets (2x1 text and graphics) customization
★ Enable widget refresh rate configuration

Edit - all it needed was a phone reboot. All good! {I'm sure it will be fixed but latest version at time of writing on S24 android 15 not-rooted it goes thru the motions bringing each app info page up but doesn't stop them. It gets stuck on the last app info page too.}

I'm sorry I ever said anything negative or nagging about your app, I've just spent enormous amount of time to find that 99% of "similar" apps, the prettier they look, the less they do, and most are just pretty bubbles of info, lol, no action can be taken, nor do they give any specific details. This is the actual real-deal, where you can actually see what's running and do something about it. Trully appreciate your work! I was terribly wrong before.

It does what it's supposed to do, but in a very crude way: by calling up the app-management page of each listed process one by one and then force-stopping it, which takes a full few seconds per process. Stopping all can take a minute or more. No way of simply killing some apps without force-stop. Very aggressive with full-screen ads, which cant be closed with Back button. Nags about "helping out development" every third run or so. Could be really awesome, but right now, it's just mediocre.

No other way indeed since Android 6 or so, thanks to limitation imposed by Google. I've just added a screen that will make the whole process better should you let the app draw over other apps. Other than that you won't find any better way of doing it on Android. If you have a PC, try 3C Companion (https://3c71.com/3cc) to get a better experience.
